Installation Precautions

We recommend that you follow the instructions given in this document for quick, correct installation of your Sepam unit: b

Equipment identification b Assembly b

Connection of inputs, current, voltage and sensors b Connection of power supply b Checking prior to commissioning

Transport, handing and storage

Sepam in its original packaging

Transport:

Sepam can be shipped to any destination by all usual means of transport without taking any additional precautions.

Handling:

Sepam can be handled without any particular care and can even withstand being dropped by a person standing at floor-level.

Storage:

Sepam can be stored in its original packaging, in an appropriate location for several years: b Temperature between -25°C and +70°C (between -13°F and +158°F) b Humidity y 90%.

Periodic, yearly checking of the environment and the packaging condition is recommended.

Energize the Sepam for 1 hour: b every 5 years for a storage temperature < 30 ° C (86 ° F) b every 3 years for a storage temperature u 30 ° C (86 ° F) b every 2 years for a storage temperature u 50 ° C (122 ° F)

Once Sepam has been unpacked, it should be energized as soon as possible.

Sepam installed in a cubicle

Transport:

Sepam can be transported by all usual means of transport in the customary conditions used for cubicles. Storage conditions should be taken into consideration for a long period of transport.

Handling:

Should the Sepam fall out of a cubicle, check its condition by visual inspection and energizing.

Storage:

Keep the cubicle protection packing for as long as possible. Sepam, like all electronic units, should not be stored in a damp environment for more than a month. Sepam should be energized as quickly as possible. If this is not possible, the cubicle reheating system should be activated.

Environment of the installed Sepam

Operation in a damp environment

The temperature/relative humidity factors must be compatible with the unit’s environmental withstand characteristics.

If the use conditions are outside the normal zone, special arrangements should be made before commissioning, such as air conditioning of the premises.

Operation in a polluted atmosphere

A contaminated industrial atmosphere (such as the presence of chlorine, hydrofluoric acid, sulfur, solvents, etc.) can cause corrosion of the electronic components, in which case environmental control arrangements should be made (such as pressurized premises with filtered air, etc.) before commissioning.

The effect of corrosion on Sepam has been tested according to the

IEC 60068-2-60 and EIA 364-65A (See "Environmental Characteristic", page 12).

Functions available according to connected voltage inputs

The availability of certain protection and metering functions depend on the phase and residual voltages measured by Sepam.

The table below gives the voltage input connection variants for which for each protection and metering function dependent on measured voltages is available.

Example:

The directional overcurrent protection function (ANSI 67N/67NC) uses residual voltage V0 as a polarization value.

It is therefore operational in the following cases: b measurement of the 3 phase-to-neutral voltages and calculation of

V0

Σ (3 V + V0Σ, variant 1) b measurement of residual voltage V0 (variant 5).

CCA630/CCA634 connector

Function

The current transformers (1 A or 5 A) are connected to the CCA630 or CCA634 connector on the rear panel of Sepam: b The CCA630 connector is used to connect three phase current transformers to

Sepam.

b The CCA634 connector is used to connect three phase current transformers and one residual current transformer to Sepam.

The CCA630 and CCA634 connectors contain interposing ring CTs with through primaries, which ensure impedance matching and isolation between the 1 A or

5 A circuits and Sepam when measuring phase and residual currents.

The connectors can be disconnected with the power on since disconnection does not open the CT secondary circuit.

DANGER

HAZARD OF ELECTRIC SHOCK, ELECTRIC ARC OR BURNS b Only qualified personnel should install this equipment. Such work should be performed only after reading this entire set of instructions and checking the technical characteristics of the device.




b To disconnect the Sepam unit current inputs, unplug the CCA630 or

CCA634 connector without disconnecting the wires from it. The CCA630 and

CCA634 connectors ensure continuity of the current transformer secondary circuits.

b Before disconnecting the wires connected to the CCA630 or CCA634 connector, short-circuit the current transformer secondary circuits.

Installation LPCT type current sensors

Function

Low Power Current Transducer (LPCT) type sensors are voltage-output sensors, which are compliant with the IEC 60044-8 standard.

The Schneider Electric range of LPCTs includes the following sensors: CLP1, CLP2,

CLP3, TLP130, TLP160 and TLP190.

CLP1 LPCT sensor

NOTICE

HAZARD OF NON-OPERATION b Set the microswitches for the CCA670/

CCA671 connector before commissioning the device.

b Check that only one microswitch is in position 1 for each block L1, L2, L3 and that no microswitch is in the center position.

b Check that the microswitch settings on all 3 blocks are identical.


CCA670/CCA671 connector

Function

The 3 LPCT sensors are connected to the CCA670 or CCA671 connector on the rear panel of Sepam.

The connection of only one or two LPCT sensors is not allowed and causes Sepam to go into fail-safe position.

The two CCA670 and CCA671 interface connectors serve the same purpose, the difference being the position of the LPCT sensor plugs: b CCA670: lateral plugs, for Sepam series 20 and Sepam series 40 b CCA671: radial plugs, for Sepam series 60 and Sepam series 80.

Description

1 3 RJ45 plugs to connect the LPCT sensors.

2 3 blocks of microswitches to set the CCA670/CCA671 to the rated phase current value.

3 Microswitch setting/selected rated current equivalency table (2 In values per position).

4 9-pin sub-D connector to connect test equipment (ACE917 for direct connector or via CCA613).

Rating of CCA670/CCA671 connectors

The CCA670/CCA671 connector must be rated according to the rated primary current In measured by the LPCT sensors. In is the current value that corresponds to the rated secondary current of 22.5 mV. The possible settings for In are (in A): 25,

50, 100, 125, 133, 200, 250, 320, 400, 500, 630, 666, 1000, 1600, 2000, 3150.

The selected In value should be: b entered as a Sepam general setting b configured by microswitch on the CCA670/CCA671 connector.

Operating mode:

1. Use a screwdriver to remove the shield located in the "LPCT settings" zone; the shield protects 3 blocks of 8 microswitches marked L1, L2, L3.

2. On the L1 block, set the microswitch for the selected rated current to "1" (2 In values per microswitch).

b The table of equivalencies between the microswitch settings and the selected rated current In is printed on the connector b Leave the 7 other microswitches set to "0".

3. Set the other 2 blocks of switches L2 and L3 to the same position as the L1 block and close the shield.

Function

The ACE990 is used to adapt measurements between an MV core balance CT with a ratio of 1/n (50 y n y 1500), and the Sepam residual current input.

Note: You must use an interface ACE990 with a core balance CT other than a CSH120, a

CSH200 or a CSH280, even if this core balance CT has the same transformation ratio than a

CSH120, CSH200 or CSH280.

Installation ACE990 Core balance CT interface

Connection

Connection of core balance CT

Only one core balance CT can be connected to the ACE990 interface.

The secondary circuit of the MV core balance CT is connected to 2 of the 5 ACE990 interface input terminals. To define the 2 input terminals, it is necessary to know the following: b Core balance CT ratio (1/n) b Core balance CT power b Close approximation of rated current In0

(In0 is a general setting in Sepam and defines the earth fault protection setting range between 0.1 In0 and 15 In0).

The table below can be used to determine: b The 2 ACE990 input terminals to be connected to the MV core balance CT secondary b The type of residual current sensor to set b The exact value of the rated residual current In0 setting, given by the following formula: In0 = k x number of core balance CT turns with k the factor defined in the table below.

The core balance CT must be connected to the interface in the right direction for correct operation: the MV core balance CT secondary output terminal S1 must be connected to the terminal with the lowest index (Ex).

K value

Example:

Given a core balance CT with a ratio of 1/400 2 VA, used within a measurement range of 0.5 A to 60 A.

How should it be connected to Sepam via the ACE990?

1. Choose a close approximation of the rated current In0,

i.e. 5 A.

2. Calculate the ratio:

approx. In0/number of turns = 5/400 = 0.0125.

3. Find the closest value of k in the table opposite to

k = 0.01136.

4. Check the mininum power required for the core balance CT:

2 VA core balance CT > 0.1 VA V OK.

5. Connect the core balance CT secondary to ACE990 input

terminals E2 and E4.

6. Set Sepam up with:

In0 = 0.0136 x 400 = 4.5 A.

This value of In0 can be used to monitor current between

0.45 A and 67.5 A.

Installation MCS025

Synchro-check module

Function

The MCS025 module is used with Sepam series 60 and Sepam series 80.

The MCS025 module checks the voltages upstream and downstream of a circuit breaker to ensure safe closing (ANSI 25).

It checks the differences in amplitude, frequency and phase between the two measured voltages, taking into account voltage abscence.

Three relay outputs may be used to send the close enable to several Sepam units.

The circuit-breaker control function of each Sepam unit will take this close enable into account.

ACE850TP communication interface.

ACE850FO communication interface.

ACE850TP and ACE850FO


Function

The ACE850 multi-protocol communication interfaces are for Sepam series 40,

Sepam series 60 and Sepam series 80.

ACE850 interfaces have two Ethernet communication ports to connect a Sepam to a single Ethernet network depending on the topology (star or ring): b For a star topology, only one communication port is used.

b For a ring topology, both Ethernet communication ports are used to provide redundancy. This redundancy conforms to the RSTP 802.1d 2004 standard.

Either port can be used for connection: b To the S-LAN (Supervisory Local Area Network) port to connect Sepam to an

Ethernet communication network dedicated to supervision, using one of the two following protocols: v IEC 61850 v Modbus TCP/IP TR A15 b To the E-LAN (Engineering Local Area Network) port, reserved for Sepam remote parameter setting and operation using the SFT2841 software

There are two versions of the ACE850 interfaces, which are identical except for the type of port featured: b ACE850TP (Twisted Pair), for connection to an Ethernet network (S-LAN or E-

LAN) using a copper RJ45 10/100 Base TX Ethernet link b ACE850FO (Fiber Optic), for connection to an Ethernet network (S-LAN or E-LAN) using a 100Base FX fiber-optic connection (star or ring)


The ACE850TP and ACE850FO multi-protocol communication interfaces are compatible with: b Sepam series 40 version u V7.00

b Sepam series 60 all versions b Sepam series 80 base version and application version u V6.00

The ACE850 multi-protocol communication interfaces will only work if TCP/IP firmware option (ref. 59754) has been ordered with Sepam series 40,

Sepam series 60 or Sepam series 80.

Performance

Redundancy performance tests have been conducted using RuggedCom switches

(RS900xx, RSG2xxx family), compatible with RSTP 802.1d 2004.

To ensure optimum performance of the protection system during communication between Sepam units via GOOSE messages, we strongly recommend setting up a fault-tolerant fiber-optic ring structure as shown in the connection examples.

Note: Protection performance during communication between Sepam units via GOOSE message is only ensured by using:

b Fiber-optic connections

b IEC 61850-compatible managed Ethernet switches

ROOT Ethernet switch

The ROOT Ethernet switch is the master switch of the RSTP reconfiguration function: b A single ROOT Ethernet switch per Ethernet network, in the main loop of the network b A Sepam unit must not be the ROOT Ethernet switch of the network

Recommendations for connecting Sepam units in ring configuration

When connecting Sepam units in the same ring configuration, the ACE850 interfaces must be of the same type (either ACE850TP or ACE850FO).

In the worst-case scenario, each Sepam unit must not be separated by more than 30 communicating devices connected to the network (other Sepam units or Ethernet switches) from the ROOT Ethernet switch.

A worst-case analysis must be performed for all the Sepam units in each network topology.

Example: b In the best-case scenario, Sepam 2 of ring 1 is separated from the ROOT Ethernet switch by 2 devices: switch 2 and Sepam 1.

b In the worst-case scenario, i.e. if the connections between switches 1 and 2 and between Sepam units 1 and 2 of ring 1 are broken, Sepam 2 of ring 1 will be separated from the ROOT Ethernet switch by 4 devices: switch 3, switch 2, Sepam

4 and Sepam 3.

Installation ACE909-2

RS 232/RS 485 converter

Function

The ACE909-2 converter is used to connect a master/central computer equipped with a V24/RS 232 type serial port as a standard feature to stations connected to a 2-wire RS 485 network.

Without requiring any flow control signals, after the parameters are set, the

ACE909-2 converter performs conversion, network polarization and automatic dispatching of frames between the master and the stations by two-way simplex

(half-duplex, single-pair) transmission.

The ACE909-2 converter also provides a 12 V DC or 24 V DC supply for the distributed power supply of the Sepam ACE949-2, ACE959 or ACE969-2 interfaces.

The communication settings should be the same as the Sepam and supervisor communication settings.

Data entry principles

The principles behind the entry of parameter and protection settings are identical.

There are four steps in modifying parameter or protection settings using the Sepam

UMI:

1. Enter the suitable password for either the protection or the parameter settings

(see "Entry of passwords", page 94).

2. Display the screen with the value to be modified (see "Display of operating

information", page 95).

3. Modify the values using one of the three entry methods offered, depending on the type of parameter or protection settings: b entry of Boolean values b selection of a value among a number of options b entry of numerical values

4. Final confirmation of all the new parameter or protection settings for use by

Sepam.

Entry of Boolean values

Boolean parameters and protection settings are shown on the Sepam display as two buttons, representing the two status conditions of Boolean data.

For example, the language used for the operating texts on the Sepam UMI is a

Boolean parameter that can have one of two states: b English b a local language (e.g. French).

To modify the value of a Boolean parameter or protection setting, proceed as follows:

1. Position the cursor using the

2. Confirm the selection using the and key.

keys.

Selection of a value among a number of options

Certain parameters and protection settings must be selected from a finite number of possibilities.

For example, the type of tripping curve for the "phase overcurrent" protection function is selected from among 16 predefined curves (DT, SIT, VIT, EIT, etc.).

To select the desired parameter or protection setting, proceed as follows:

1. Position the cursor on the value to be modified using the and keys.

2. Confirm using the key.

3. Scroll the possibilities using the and

Logic-equation editing

Presentation

Logic-equation editing consists of: b entry and checks on logic equations b setting the delays used in the logic equations b loading the logic equations in Sepam.

The logic-equation editor of the SFT2841 software is accessed via the icon. It is authorized only when the Logipam program linked to the Sepam configuration is not installed.

The logic-equation editor includes:

1 a zone to enter and display the logic equations

2 an editing assistance tool

3 a tool for setting time delays.

2

Entry of logic equations

The syntax required for logic equations is presented in the manual on Sepam series

80 functions, in the "Control and monitoring functions" section.

Logic equations are entered in text: b directly in the equation entry zone b or using the editing assistance tool.

The editing assistance tool offers guided access to variables, operators and functions. Via the tab sheets and tree structures, the user can select program elements and then click the "Add" button. The selected element is placed in the entry zone.

Check on the logic equations

The syntax of logic equations can be checked by clicking: b the "Equation check" button during entry of logic equations b the "Apply" button during final confirmation of the logic equations entered.

An error message is displayed if the check detects an error. The message indicates the type of error and the line containing the error.

Setting time delays

Time delays can be entered directly in a logic equation.

Example: V1= TON(VL1, 100), "On" time delay, set to delay the shift to 1 of variable

VL1 by 100 ms.

To improve equation legibility and facilitate time delay settings, it is preferable to use the time delay editor to: b create a time delay, indicating its duration and name (used in writing the logic equation) b delete a time delay b adjust a time delay by modifying its duration without having to make changes in the equation entry zone b display the list of delays used in the logic equations, with their names and durations.

Example:

Create SwitchOnDelay with a duration of 100 ms.

In the entry zone, use the time delay: V1=TON(VL1, SwitchOnDelay).

Load the logic equations in Sepam

Logic equations are transferred to Sepam in connected mode: b directly by clicking the "Apply" button b when a configuration file containing logic equations entered in disconnected mode is loaded.

In both cases, loading results in a short interruption in Sepam operation and automatic restart at the end of loading.

Presentation

The Logipam screen in the SFT2841 software is used to: b link a Logipam program to the configuration of a Sepam b set program parameters b view the internal program variables to assist in program set-up.

The Logipam program must first be entered and confirmed using the SFT2885 software.

The Logipam screen of the SFT2841 software is accessed via the icon.

The Logipam screen can be accessed in connected mode with a Sepam if the latter has the Logipam SFT080 option. In disconnected mode, the Logipam screen is still accessible, but the configuration files containing a Logipam program can be loaded exclusively to Sepam units with the SFT080 option.

The Logipam screen has five tabs: b Logipam: selection of the program and its operating mode b Internal bits: view the internal bits and set the configuration bits b Counters: view the current value and set the counters b Delays: view the state and set the timers b Clocks: set the clocks.

Link a Logipam program to the configuration of a Sepam

A Logipam program is linked to the configuration of a Sepam by selecting the program file using the "Select" button on the Logipam tab sheet.

The programs are stored in the Logipam subdirectory of the SFT2841 installation directory (by default C:\Program Files\Schneider\SFT2841\Logipam). They have the extension .bin.

Once the program has been selected, the program properties are indicated (name, version, author, installation characteristics, etc.).

The "Apply" button is used as indicated below: b In disconnected mode, it stores the name of the Logipam program in the Sepam configuration file.

The program is then loaded in Sepam at the same time as the configuration file.

b In connected mode, it stores the name of the Logipam program in the Sepam configuration file and loads the program in Sepam.

The "Delete" button eliminates the link between the Logipam program and the configuration file.

In connected mode, the name of the Logipam program is deleted in the Sepam memory cartridge when the "Apply" button is clicked.

The operating mode of the Logipam must be selected: b On: the program runs immediately after it is loaded b Off: the program does not run and program outputs remain set to 0.

Processing by the Logipam program can thus be temporarily postponed, e.g. if the program has not yet been fully set up.

Connection window

The SFT2841 software connection window is used: b To select an existing Sepam network or configure a new one b To set up the connection to the selected Sepam network b To select one Sepam unit from the network and access its parameters, settings, and operation and maintenance information.

Configuration of a Sepam network

Several configurations can be defined for the various Sepam installations.

A Sepam network configuration is identified by a name. It is saved on the SFT2841

PC in a file in the SFT2841 installation directory (default: C:\Program

Files\Schneider\SFT2841\Net).

Configuration of a Sepam network is in 2 parts: b Configuration of the communication network b Configuration of the Sepam units.

Configuration of the communication network

To configure the communication network, first define: b The type of link between the PC and the Sepam network b The communication parameters, according to the type of link selected: v direct serial link v link via Ethernet TCP/IP v link via telephone modem.

Configuration windows for the communication network, according to the type of link: serial link, modem link (STN) or Ethernet link (TCP).

116 SEPED303003EN - 01/2013



Direct serial link

The Sepam units are connected to an RS 485 (or fiber-optic) multidrop network.

Depending on the serial link interfaces available on the PC, the PC itself will be connected either directly to the RS 485 network (or fiber-optic HUB), or via an

RS 232/RS 485 converter (or fiber-optic converter).

The communication parameters to be defined are: b port: communication port used on the PC b speed: 4800, 9600, 19200 or 38400 bauds b parity: None, Even or Odd b handshake: None, RTS or RTS-CTS b time-out: from 100 to 3000 ms b number of retries: from 1 to 6.

Configuration window for the serial link communication network.

Configuration window for the Ethernet TCP/IP communication network.

Link via Ethernet TCP/IP

The ACE850 communication interface can be used to connect a Sepam series 40 or series 80 unit directly to an Ethernet network.

The Sepam series 20, series 40 and series 80 units can also be connected to an

RS 485 multidrop network over one or more Ethernet Modbus TCP/IP gateways (for example: EGX gateways or ECI850 servers that act as Modbus TCP/IP gateways for the link with the SFT2841 software).

Use on an IEC 61850 network

SFT2841 can be used on an IEC 61850 network. In this case, it can be used to define the IEC 61850 configuration of Sepams connected to this network. See the Sepam

IEC 61850 Communication user's manual (reference SEPED306024EN) for more information.

Configuration of the Modbus TCP/IP gateway

See the setup manual for the gateway used.

In general, the gateway should be assigned an IP address.

The configuration parameters for the gateway’s RS 485 interface must be defined in accordance with the Sepam communication interface configuration: b speed: 4800, 9600, 19200 or 38400 bauds b character format: 8 data bits + 1 stop bit + parity (none, even, odd).

Configuration of communication on SFT2841

When configuring a Sepam network on SFT2841, the following communication parameters must be defined: b type of device: Modbus gateway, ECI850 or Sepam b IP address: IP address for the connected remote equipment b time-out: from 100 to 3000 ms.

A time-out of between 800 ms and 1000 ms is sufficient in most installations.

Communication via the TCP/IP gateway may, however, be slowed down if other applications want Modbus TCP/IP or IEC 61850 access at the same time.

The time-out value should then be increased (2 to 3 seconds).

b number of retries: from 1 to 6.

Note 1: SFT2841 uses the Modbus TCP/IP communication protocol.

Although communication is IP-based, use of SFT2841 is restricted to a local installation network based on an Ethernet network (LAN – Local Area Network).

The operation of SFT2841 over a WAN (Wide Area Network) cannot be guaranteed because of the presence of some routers or firewalls that may reject the Modbus protocol, causing communication times that would be incompatible with Sepam.

Note 2: SFT2841 allows Sepam protection settings to be modified, and direct activation of the outputs. These operations, which could involve the operation of electrical switchgear (opening and closing), and thus risk the safety of people and installations, are protected by the Sepam password. In addition to this protection, the E-LANs and S-LANs must be designed as private networks, protected from external actions by all suitable methods.

Use

Configuration window for the communication network via telephone modem.



Link via telephone modem

The Sepam units are connected to an RS 485 multidrop network using an industrial

STN modem.

This modem is the called modem. It must first be configured, either via AT commands from a PC using HyperTerminal or the configuration tool that may have been supplied with the modem, or by setting switches (see the modem manufacturer’s manual).

The PC may use an internal or an external modem. This modem on the PC side is always the calling modem. It must be installed and configured in accordance with the

Windows modem installation procedure.

Configuration of the calling modem in SFT2841

When configuring a Sepam network, SFT2841 displays the list of all the modems installed on the PC.

The communication parameters to be defined are: b modem: select one of the modems listed by SFT2841 b telephone no.: no. of the remote modem to be called b speed: 4800, 9600, 19200 or 38400 bauds b parity: none (not adjustable) b handshake: none, RTS or RTS-CTS b time-out: from 100 to 3000 ms.

Communication via modem and telephone network is slowed considerably because of the transit time through the modems. A time-out of between 800 ms and 1000 ms is sufficient in most 38400 baud installations. In some cases, the poor quality of the telephone network may require a slower speed (9600 or 4800 bauds). The time-out value should then be increased (2 to 3 seconds).

b number of retries: from 1 to 6.

Note: the speed and parity of the calling modem must be configured under Windows with the same values as for SFT2841.

Configuration of called modem

The modem on the Sepam side is the called modem. It must first be configured, either via AT commands from a PC using HyperTerminal or the configuration tool that may have been supplied with the modem, or by setting switches (see the modem manufacturer’s manual).

Modem RS 485 interface

In general, the configuration parameters for the modem’s RS 485 interface must be defined in accordance with the Sepam communication interface configuration: b speed: 4800, 9600, 19200 or 38400 bauds b character format: 8 data bits + 1 stop bit + parity (none, even, odd).

Telephone network interface

Modern modems offer sophisticated features such as checking the quality of the telephone line, error correction and data compression. These options are not appropriate for communication between SFT2841 and Sepam, which is based on the

Modbus RTU protocol. Their effect on communication performance may be the opposite of the expected result.

It is therefore highly advisable to: b Invalidate the error correction, data compression and telephone line quality monitoring options b Use the same end-to-end communication speed between: v the Sepam network and the called modem v the called modem (Sepam side) and the calling modem (PC side) v the PC and the calling modem (see recommended configurations table).

Industrial configuration profile

The following table shows the main characteristics of the modem on the Sepam side.

These characteristics match a configuration profile commonly known as an

"industrial profile", as opposed to the configuration of modems used in offices.

Presentation

Description

SFT2841 Sepam setting and operating software includes a mimic-diagram editor that can be used to personalize the mimic diagram for local control on the mimicbased UMI of Sepam series 80 units.

A mimic-diagram or single-line diagram is a simplified diagram of an electrical installation. It is made up of a fixed background on which symbols and measurements are placed.

The mimic-diagram editor can be used to: b create a fixed, bitmap background (128 x 240 pixels) using standard drawing software b create animated symbols or use predefined animated symbols to represent the electrotechnical devices or other objects b assign the logic inputs or internal status conditions that modify the animated symbols. For example, the logic inputs for the circuit-breaker position must be assigned to the circuit-breaker symbol to enable the display of the open and closed conditions b assign the logic outputs or internal status conditions that are activated when an opening or closing order are issued for the symbol b display the current, voltage and power measurements on the mimic diagram.

Mimic-diagram and symbols

The symbols making up the mimic-diagram constitute the interface between the mimic-based UMI and the other Sepam control functions.

There are three types of symbols: b Fixed symbol: represents the electrotechnical devices that are neither animated or controlled, e.g. a transformer b Animated symbol with one or two inputs: represents the electrotechnical devices that change on the mimic diagram, depending on the symbol inputs, but cannot be controlled via the Sepam mimic-based UMI.

This type of symbol is used for switch-disconnectors without remote control, for example.

b Controlled symbol with one or two inputs/outputs: represents the electrotechnical devices that change on the mimic diagram, depending on the symbol inputs, and can be controlled via the Sepam mimic-based UMI.

This type of symbol is used for circuit breakers, for example.

The symbol outputs are used to control the electrotechnical device: v directly via the Sepam logic outputs v by the switchgear control function v by logic equations or the Logipam program.

Local control using a symbol

"Controlled - 1 input/output" and "Controlled - 2 inputs/outputs" symbols are used to control the switchgear corresponding to the symbol via the Sepam mimic-based UMI.

Control symbols with two outputs

"Controlled - 2 inputs/outputs" symbols have two control outputs for opening and closing of the symbolized device.

An order on the mimic-based UMI sends a 300 ms pulse on the controlled output.

Control symbols with one output

"Controlled - 1 input/output" symbols have one control output. The output remains in the last state to which it was ordered.

A new order results in a change in the output state.

Inhibition of orders

"Controlled - 1 input/output" and "Controlled - 2 inputs/outputs" symbols have two inhibition inputs that, when set to 1, block opening and closing orders. This makes it possible to create interlocking systems or other order-disabling systems that are taken into account by the UMI.

Symbol animation

Depending on the value of their inputs, symbols change. A graphic representation corresponds to each state. Animation is carried out automatically by changing the symbol each time the state changes.

The symbol inputs must be assigned directly to the Sepam inputs indicating the position of the symbolized switchgear.

Animated symbols with two inputs

"Animated - 2 inputs" and "Controlled - 2 inputs/outputs" symbols are animated symbols with two inputs, one open and the other closed.

This is the most common situation in representing switchgear positions.

The symbol has three states, i.e. three graphic representations: open, closed and unknown.

The latter is obtained when the inputs are not matched, in which case it is impossible to determine the position of the switchgear.

Symbol inputs Symbol state Graphic representation

(example)

Input 1 (open) = 1

Input 2 (closed) = 0

Open

Input 1 (open) = 0


Closed

Input 1 (open) = 0


Input 1 (open) = 1


Unknown

Animated symbols with one input

"Animated -1 input" and "Controlled -1 input/output" symbols are animated symbols with one input. The value of the input determines the state of the symbol: b input set to 0 = inactive b input set to 1 = active

This type of symbol is used for simple presentation of information, for example the racked out position of a circuit breaker.

Commissioning Principles

DANGER


ARC OR BURNS b Only qualified personnel should commission this equipment. Such work should be performed only after reading this entire set of instructions.

b NEVER work alone.

b Obey all existing safety instructions when commissioning and maintaining high-voltage equipment.

b Beware of potential hazards and wear personal protective equipment.


Protection relay testing

Protection relays are tested prior to commissioning, with the dual aim of maximizing availability and minimizing the risk of malfunctioning of the assembly being commissioned. The problem consists of defining the consistency of the appropriate tests, keeping in mind that the relay is always involved as the main link in the protection chain.

Therefore, protection relays based on electromechanical and static technologies, the performances of which are not totally reproducible, must be systematically submitted to detailed testing, not only to qualify relay commissioning, but also to check that they actually are in good operating order and maintain the required level of performance.

The Sepam concept makes it possible to do away with such testing, since: b the use of digital technology guarantees the reproducibility of the performances announced b each of the Sepam functions has undergone full factory-qualification b an internal self-testing system provides continuous information on the state of the electronic components and the integrity of the functions (e.g. automatic tests diagnose the level of component polarization voltages, the continuity of the analog value acquisition chain, non-alteration of RAM memory, absence of settings outside the tolerance range) and thereby guarantees a high level of availability

Sepam is therefore ready to operate without requiring any additional qualification testing that concerns it directly.

Sepam commissioning tests

The preliminary Sepam commissioning tests may be limited to a commissioning check, i.e.: b checking of compliance with BOMs and hardware installation diagrams and rules during a preliminary general check b checking of the compliance of the general settings and protection settings entered with the setting sheets b checking of current or voltage input connections by secondary injection tests b checking of logic input and output connections by simulation of input data and forcing of output status b validation of the complete protection chain (possible customized logical functions included) b checking of the connection of the optional MET148-2, MSA141 and MSC025 modules.

The various checks are described on the next page.

132 SEPED303003EN - 01/2013

Commissioning Methods

General principles

b All the tests should be carried out with the MV cubicle completely isolated and the MV circuit breaker racked out (disconnected and open) b All the tests are to be performed in the operating situation. We strongly recommend that you do not modify, even temporarily, the wiring or the settings to facilitate testing.

The SFT2841 parameter setting and operating software is the basic tool for all

Sepam users. It is especially useful during Sepam commissioning tests. The tests described in this document are systematically based on the use of that tool.

For each Sepam: b only carry out the checks suited to the hardware configuration and the functions activated

(A comprehensive description of all the tests is given further on) b use the test sheet provided to record the results of the commissioning tests.

Checking of current and voltage input connections

The secondary injection tests to be carried out to check the connection of the current and voltage inputs are described according to: b the type of current and voltage sensors connected to Sepam, in particular for residual current and voltage measurement b the type of injection generator used for the tests: three-phase or single-phase generator b the type of Sepam.

The different possible tests are described further on by: b a detailed test procedure b the connection diagram of the associated test generator.

Determination of checks to be carried out

The table below indicates the page on which the following are described: b general tests to be performed according to the type of measurement sensors and type of generator used b additional tests to be performed for certain types of Sepam, with a single or threephase generator

Commissioning General examination and preliminary actions

Checking to be done prior to energizing

Apart from the mechanical state of the equipment, use the diagrams and BOMs provided by the contractor to check: b identification of Sepam and accessories determined by the contractor b correct earthing of Sepam (via terminal 13 of the 20pin connector E and the functional earthing terminal located on the back of the Sepam unit) b correct connection of auxiliary voltage (terminal 1: positive polarity; terminal 2: negative polarity) b presence of the DPC (detection of plugged connectors) bridge on terminals 19-20 of the 20-pin connector E .

b presence of a residual current measurement core balance CT and/or additional modules connected to

Sepam, when applicable b presence of test terminal boxes upstream from the current inputs and voltage inputs b conformity of connections between Sepam terminals and the test terminal boxes.

Connections

Check that the connections are tightened (with equipment non-energized).

The Sepam connectors must be correctly plugged in and locked.

Energizing

Switch on the auxiliary power supply.

Check that Sepam performs the following initialization sequence, which lasts approximately 6 seconds: b green ON and red indicators on b red indicator off b pick-up of "watchdog" contact.

The first screen displayed is the phase current measurement screen.

Implementation of the SFT2841 software for PC

1. Start up the PC.

2. Connect the PC RS 232 serial or USB port to the communication port on the front panel of Sepam using the CCA783 or CCA784 cord.

3. Start up the SFT2841 software, by clicking on the related icon.

4. Choose to connect to the Sepam to be checked.

Identification of Sepam

1. Note the Sepam serial number given on the label stuck to the right side plate of the base unit.

2. Note the references defining the type of application indicated on the adhesive label on the Sepam cartridge.

3. Note the Sepam type and software version using the

SFT2841 software, "Sepam Diagnosis" screen.

4. Enter them in the test sheet.

Determination of parameter and protection settings

All of the Sepam parameter and protection settings are determined ahead of time by the design department in charge of the application, and should be approved by the customer.

It is presumed that the study has been carried out with all the attention necessary, or even consolidated by a network coordination study.

All of the Sepam parameter and protection settings should be available at the time of commissioning: b in paper file format (with the SFT2841 software, the parameter and protection setting file for a Sepam may be printed directly) b and, when applicable, in the format of a file to be downloaded into Sepam using the SFT2841 software.

Checking of parameters and protection settings

Check to be made when the Sepam parameter and protection settings have not been entered or downloaded during commissioning testing, to confirm the conformity of the parameter and protection settings entered with the values determined during the study.

The aim of this check is not to confirm the relevance of the parameter and protection settings.

1. Go through all the parameter and protection setting screens in the SFT2841 software, in the order proposed in guided mode.

2. For each screen, compare the values entered in the Sepam with the values recorded in the parameter and protection setting file.

3. Correct any parameter and protection settings that have not been entered correctly, proceeding as indicated in the SFT2841 section of the Use chapter of this manual.

Conclusion

Once the checking has been done and proven to be conclusive, as of that phase, the parameter and protection settings should not be changed any further and are considered to be final.

In order to be conclusive, the tests which follow must be performed with these parameter and protection settings. We strongly recommend that you do not modify, even temporarily, any of the existing values to facilitate testing.

Commissioning Checking of phase current input connections

For differential applications

Description

Check to be carried out for differential applications

(machine, transformer or transformer-machine unit).

This test is carried out along with checking of the phase current and phase voltage input wiring. The purpose is to check the wiring of the second Sepam current input.

Procedure

1. Connect the generator current terminals to the corresponding current test terminal boxes using the plugs provided, according to the block diagram below.

Block diagram

Should the secondary circuits of the CTs connected to each of the Sepam current inputs not have the same ratings (1 and 5 A or 5 and 1 A), set the injection to the lowest secondary rating. The value indicated for the phase currents (I1, I2, I3) or (I’1, I’2, I’3), as the case may be, is then equal to the CT rated primary current divided by 5 (In/5).


3. Inject, in series, into the phase 1 current input terminals of each Sepam connector B1 , B2 connected in opposition (via the test boxes, according to the diagram above), current I from the generator, set to match the CT rated secondary current (1 A or 5 A).

4.

LPCT type current sensors

Phase current measurement by LPCT sensors

b The 3 LPCT current sensors are connected via an

RJ45 plug to the CCA671 connector which is to be mounted on the rear panel of Sepam, identified as B1 and/or B2 .

b The connection of only one or two LPCT sensors is not allowed and causes Sepam to go into the fail-safe position.

b The rated primary current In measured by the LPCT sensors is to be entered as a Sepam general setting and configured by microswitches on the CCA671 connector.

Restrictions on the use of LPCT type current sensors

LPCT type current sensors may not be used for the following measurements: b phase current measurements for Sepam T87, M88 and G88 units with ANSI 87T transformer differential protection ( B1 and B2 connectors) b phase current measurement for Sepam B83 (

B1 connector) b unbalance current measurement for Sepam C86

( B2 connector).

Procedure

The tests to be carried out to check phase current input connections are the same whether the phase currents are measured by CTs or LPCT sensors. Only the Sepam current input connection procedure and current injection values change.

To test current inputs connected to LPCT sensors with a standard injection box, the

ACE917 injection adapter is required.

The ACE917 adapter is inserted between: b the standard injection box b the LPCT test plug: v integrated in the Sepam CCA671 connector v or transferred by means of the CCA613 accessory.

The ACE917 injection adapter should be set according to the currents selected on the CCA671 connector: the ACE917 setting should be equal to the number of the microswitch that is set to 1 on the CCA671.

The injection value depends on the rated primary current selected on the CCA671 connector and entered in the Sepam general settings, i.e.: b 1 A for the following values (in Amps): 25, 50, 100, 133, 200, 320, 400, 630 b 5 A for the following values (in Amps): 125, 250, 500, 666, 1000, 1600, 2000, 3150.

In some cases, reading of the ϕ0 or ϕ’0 angle is impossible due to the position of the core balance CT (e.g.: transformer tank earthing cable or neutral point) or because only one of the two I0 or V0 measurements is necessary or possible. When this is the case, simply check the measured residual current value

I0 or I’0.


3. Apply a V-N voltage set to the rated secondary voltage of the VTs connected in an open delta arrangement (i.e. Uns/3 or Uns/3)

4. inject an I current set to 5 A, and in phase with the voltage applied (i.e. generator phase displacement

α(V-N, I) = 0°).

5. Use the SFT2841 software to check the following: b the value indicated for the measured I0 residual current is approximately equal to

5 A b the value indicated for the measured V0 residual voltage is approximately equal to the rated primary phase-to-neutral voltage of the VTs (i.e. Vnp = Unp/3) b the value indicated for the phase displacement ϕ0(V0, I0) between the I0 current and V0 voltage is approximately equal to 0°

6. Use the same procedure if the I’0 input is connected. When this is the case, the phase displacement angle to be checked is ϕ’0(V0, I’0), between the I’0 current and

V0 voltage.

Description

Check to be carried out when the residual current is measured by a specific sensor such as: b CSH120 or CSH200 core balance CT b CSH30 interposing ring CT (whether it is installed on the secondary circuit of a single 1 A or 5 A CT which encompasses the 3 phases, or on the neutral connection of the three 1 A or 5 A phase CTs) b other core balance CT connected to an ACE990 interface, b and when the residual voltage is calculated in Sepam or cannot be calculated (e.g.: assembly with 2 VTs connected via their primary circuits) and is therefore not available for the protection function.

Procedure

1. Connect according to the diagram below: b a wire between the generator current terminals to inject current into the primary circuit of the core balance CT or CT, with the wire passing through the core balance

CT or CT in the P1-P2 direction, with P1 the busbar end and P2 the cable end b when applicable, the generator voltage terminals to the voltage test terminal box, so as to only supply Sepam’s phase 1 voltage input and therefore obtain a residual voltage V0 = V1.

Sepam series 80 is equipped with 2 independent residual current inputs which may be connected to a core balance CT installed on the cables, tank earthing cable or neutral point of a transformer, or on the earthing cable of a motor or generator. In some cases, reading of the ϕ0 or ϕ’0 angle is impossible due to the position of the core balance CT (e.g. transformer neutral point or tank earthing cable) or because only one of the two I0 or V0 measurements is necessary or possible. When this is the case, simply check the measured residual current value I0 or I’0.


3. When applicable, apply a V-N voltage set to the rated secondary phase-to-neutral voltage of the VT (i.e. Vns = Uns/3).

4. Inject an I current set to 5 A, and when applicable in phase with the V-N voltage applied (i.e. generator phase displacement

α(V-N, I) = 0°).

5. Use the SFT2841 software to check the following: b the value indicated for the measured I0 residual current is approximately equal to

5 A b when applicable, the value indicated for calculated V0 residual voltage is approximately equal to the rated primary phase-to-neutral voltage of the VTs

(i.e. Vnp = Unp/3) b when applicable, the value indicated for the phase displacement ϕ0 (V0, I0) between the I0 current and V0 voltage is approximately equal to 0°

6. Use the same procedure if the I’0 input is connected. When this is the case, the phase displacement angle to be checked is ϕ’0(V0, I’0), between the I’0 current and

V0 voltage.

SFT2841: GOOSE logic input test

Checking of GOOSE logic input connections

Procedure

This check is carried out using the "GOOSE test" screen accessed from the "Input, output and LED status" tab in the SFT2841 software.

This screen can be used to perform 2 types of test on GOOSE logic inputs: b A test by controlling a GOOSE test variable b A test by forcing remote indications (TS)

Test by controlling a GOOSE test variable

The test by controlling a GOOSE test variable is used to check that IEC 61850 communication is fully operational with all the Sepam units included in the IEC 61850 configuration.

This test allows to activate 4 GOOSE logic input test variables

(LD0.GSE_GGIO1_Test1 to LD0.GSE_GGIO1_Test4).

These 4 GOOSE logic input test variables use 4 test data items defined in the

IEC 61850 model of the Sepam units.

Using the SFT850 software, the user configures the test logic to be used with these

4 test variables.

Clicking on the [Test] button sets the selected GOOSE test variables to 1 for the duration specified.

Test by forcing remote indications (TS)

The test by forcing remote indications is used to check the configuration of the relays subscribed to the GOOSE inputs to be used and the control logic associated with the

GOOSE inputs to which the Sepam is subscribed.

The screen initially displays the actual state of the Sepam remote indications

For each remote indication to be enforced, the test consists of:

1. Select the number of the remote indication to be forced by placing the pointer on the corresponding numbered box. If it exists, the description of the IEC 61850 variable corresponding to the remote indication appears in a pop-up.

2. Check that the remote indication selected matches the IEC 61850 variable displayed in the pop-up.

3. Click on the remote indication(s) to be forced: b Click once to force to 0 b Click twice to force to 1

4. Set the test duration by entering the desired value.

5. Click the [Test] button: All the selected remote indications are forced for the set duration.

This function is available whether the SFT2841 software is connected on the front panel of the Sepam or to a Sepam network.

Maintenance Maintenance tests

DANGER


ARC OR BURNS b Only qualified personnel should maintain this equipment. Such work should be performed only after reading this entire set of instructions.

b NEVER work alone.

b Obey all existing safety instructions when commissioning and maintaining high-voltage equipment.

b Beware of potential hazards and wear personal protective equipment.


General

The logic inputs and outputs and the analog inputs are the parts of Sepam least covered by the self-tests. (The list of Sepam self-tests can be found in the Control and monitoring functions section of the Sepam series 80 function user's manual, reference SEPED303001EN).

They should be tested during a maintenance operation.

The recommended interval between preventive maintenance operations is 5 years.


To perform maintenance on Sepam, see Section 3, page 132. Carry out all the

recommended commissioning tests according to the type of Sepam to be tested, except for the test specific to the differential function which is not necessary. If the

MCS025 Synchro-check module is present, test its voltage inputs as well.

First test all the logic inputs and outputs involved in tripping the circuit breaker.

A test of the complete chain including the circuit breaker is also recommended.
