Chapter 1: AC Power

Measurement

AC Power Measurement

The economics of electric power distribution networking dictate several configurations of

AC power transmission. The number of phases and voltage levels characterize these configurations.

1.1

Single Phase System

A single phase system is a basic two-wire system used in low power distribution applications, such as residential communities or offices. Typically, the voltage is 120V AC.

For higher power requirements, such as small commercial facilities, the typical power configuration is two lines of 120V AC opposite in phase (see Figure 1.1 B, below).

This system produces 120 volts from line to neutral for lighting and small appliance use.

The line-to-line voltage is 240V AC, used for higher loads such as water heaters, electric dryers, ranges and machinery.

EPM 5300 SERIES ADVANCED POWER METERS – INSTRUCTION MANUAL 1–1

SINGLE PHASE SYSTEM CHAPTER 1: AC POWER MEASUREMENT

The power (W) in a single phase system is:

W = E • I • cos

Θ

E = potential, I = current, and cos Θ = phase difference between the potential and the current.

Power in a 120/240V AC system is:

W = (E

Line 1

• I

Line 1

• cos

Θ

) + (E

Line 2

• I

Line 2

• cos

Θ

)

Phase differential between the potential and the current results from a non-resistive load, either reactive or capacitive.

Reactive power (VAR): The additional power consumed that does not produce any work but must be delivered to the load: .

VAR = E

I

⋅ s

in

Θ

This is a measure of the inefficiency of the electrical system.

Apparent power (VA): The total power delivered to the load, and the vector sum of real power and reactive power.

Power Factor (PF): The ratio between real power and apparent power:

Apparent Power (VA)

Reactive

Power

(VAR)

Real Power (W)

FIGURE 1–2: Relationship between apparent, real and reactive power

Ideal power distribution should have a PF of 1. This condition can be met only if no reactive power loads exist. In real life applications, many loads are inductive loads. Often, corrective capacitors are installed to correct Poor Power Factor (see Section 1.3).

1–2 EPM 5300 SERIES ADVANCED POWER METERS – INSTRUCTION MANUAL

CHAPTER 1: AC POWER MEASUREMENT THREE-PHASE SYSTEM

1.2

Three-Phase System

A three-phase system delivers higher levels of power for industrial and commercial applications; the three phases correspond to three potential lines. A 120° phase shift exists between the three potential lines.

A typical configuration has either a Delta connection or a Wye connection (see Figure 1.3, below).

In a three-phase system, the voltage levels between the phases and the neutral are uniform and defined by:

FIGURE 1–3: Three-Phase System: (1) Delta, (2) Wye

Voltages between the phases vary depending on loading factors and the quality of distribution transformers. The three-phase system is distributed in different voltage levels:

208V AC, 480V AC, 2400V AC, 4160V AC, 6900V AC, 13800V AC, and so on.

Power measurement in a poly phase system is governed by Blondel's Theorem. Blondel’s

Theorem states that in a power distribution network which has N conductors, the number of measurement elements required to determine power is N-1. A typical configuration of poly phase system has either a Delta connection or a Wye connection (see Figure 1.4, below).

CHAPTER 1: AC POWER MEASUREMENT CONSUMPTION, DEMAND AND POOR POWER FACTOR

1.3

Consumption, Demand and Poor Power Factor

CONSUMPTION:

WH = W

×

T

W = instantaneous power T = time in hours

The total electric energy usage over a time period is the consumption of WH.

Typically, the unit in which consumption is specified is the kilowatt-hour (KWH): one thousand watts consumed over one hour. Utilities use the WH equation to determine the overall consumption in a billing period.

DEMAND: Average energy consumed over a specified time interval. The utility determines the interval, typically 15 or 30 minutes. The utility measures the maximum demand over a billing period. This measurement exhibits a deviation from average consumption, causing the utility to provide generating capacity to satisfy a high maximum consumption demand.

The highest average demand is retained in the metering system until the demand level is reset.

POOR POWER FACTOR: Results in reactive power consumption. Transferring reactive power over a distribution network causes energy loss. To force consumers to correct their

Power Factor, utilities monitor reactive power consumption and penalize the user for Poor

Power Factor.

EPM 5300 SERIES ADVANCED POWER METERS – INSTRUCTION MANUAL 1–5

WAVEFORM AND HARMONICS CHAPTER 1: AC POWER MEASUREMENT

1.4

Waveform and Harmonics

Ideal power distribution has sinusoidal waveforms on voltages and currents. In real-life applications, where inverters, computers, and motor controls are used, distorted waveforms are generated. These distortions consist of harmonics of the fundamental frequency.

HARMONIC DISTORTION: A destructive force in power distribution systems. It creates safety problems, shortens the life span of distribution transformers, and interferes with the operation of electronic devices. The Futura+ monitors the harmonic distortion to the 31st harmonic. A waveform capture of distorted waveform is also available.

Electrical Installation

3.1

Connecting the Current Circuit

Install the wiring for the current at 600V AC insulation as a minimum. The cable connector should be rated for 6 Amps or greater and have a cross-sectional area of 16 AWG minimum.

Mount the current transformers (CTs) as close as possible to the meter for best accuracy.

The following table illustrates the maximum recommended distances for various CT sizes, assuming the connection is via 16 AWG cable.

DO NOT leave secondary of the CT open when primary current is flowing. This causes high voltage that will overheat the secondary of the CT. Use a shorting block on the secondary of the CT.

EPM 5300 SERIES ADVANCED POWER METERS – INSTRUCTION MANUAL 3–5

CT CONNECTION CHAPTER 3: ELECTRICAL INSTALLATION

Note

3.2

CT Connection

If the meter is connected directly to the current (up to 10 Amps max.), maintain the exact connection to avoid incorrect polarity.

When the meter is connected using the CTs, you must maintain the correct CT polarities. CT polarities are dependent upon correct connections of CT leads, and upon the direction the

CTs are facing when clamped around conductors. The dot on the CT must face the line side; the corresponding secondary connection must connect to the appropriate input on the meter. Failure to connect CTs properly results in inaccurate power readings. If your meter is not reading power properly, it is more than likely the CT is incorrectly wired.

CTs are shorted if connected to the terminal block model DSP2 or 3 even if it is detached from the meter.

3.2.1

Helpful Debugging Tools

Option 1: Isolating a CT Connection Reversal power reading

If your meter does not read the correct watts after installation, it almost always means that the CT’s have been wired in the wrong polarity. To check the polarity of the CT after the monitor has been installed, look at the single phase WATT readings to see that each of the readings are positive (assuming you are consuming power). If one of the WATT readings is negative, that particular phase CT is reversed.

To check the single phase WATT reading, press the Power button twice while the annunciator is positioned to WATTS. Then press the Phase/Next button to cycle through the phases. After connecting the polarity of the CTs, the WATT and VAR readings should be correct.

Option 2: Isolating a CT Connection Reversal using Voltage Readings

Z KW reading. It should be positive.

Z If negative, reverse the CT wires on terminals 8 and 9.

Z Connect terminal number 6 potential. If KW decreases to about zero, reverse CT wires on terminals 10 and 11.

Z Connect terminal number 7 potential. If KW is one-third of expected reading, reverse CT wires to terminals 12 and 13.

3–6 EPM 5300 SERIES ADVANCED POWER METERS – INSTRUCTION MANUAL

CHAPTER 3: ELECTRICAL INSTALLATION CONNECTING THE VOLTAGE CIRCUIT

3.3

Connecting the Voltage Circuit

For proper meter operation, the voltage connection must be maintained. The voltage must correspond to the correct terminal.

The cable required to terminate the voltage sense circuit should have an insulation rating greater than 600V AC and a current rating greater than 0.1 A.

EPM 5300 SERIES ADVANCED POWER METERS – INSTRUCTION MANUAL 3–7

SELECTING THE VOLTAGE FUSES CHAPTER 3: ELECTRICAL INSTALLATION

3.4

Selecting the Voltage Fuses

We strongly recommend using fuses on each of the sense voltages and the control power, although connection diagrams do not show them. Use a 1 Amp fuse on each voltage input.

The meter can handle a maximum voltage of 150V phase to neutral. PTs are required for higher voltages. Suffix -G extends the maximum direct voltage to 300V phase to neutral,

600 volt phase to phase.

For DC-powered units, polarity should be observed. Connect the negative terminal to L and positive terminal to L1. An earth ground connection to chassis is mandatory for normal operation (terminal three). Do not ground the unit through the negative of the DC supply.

Externally fuse power supply with a slow-blow 3 Amp fuse.

ELECTRICAL CONNECTION INSTALLATION CHAPTER 3: ELECTRICAL INSTALLATION

Note

3.6

Electrical Connection Installation

Choose the diagram that best suits your application and maintain the CT polarity. Follow the outlined procedure to verify correct connection.

IMPORTANT: For PT connections only, short terminals 3 and 4.

Note

Note

Connect local ground to terminal 3. This protects the unit from spikes and transients.

• The meter and terminal module DSP3 are factory calibrated together; the serial numbers are matched on both. The DSP3 input module and the meter base MUST

MATCH!

• Mismatching of the meter and DSP3 input module will cause inaccurate readings because calibration ratios are stored in the meter’s memory, not in the DSP3 input module.

RELAY, PROTECTION AND PULSE OUTPUT CHAPTER 3: ELECTRICAL INSTALLATION

Relay, Protection and Pulse Output

(This section applies only to the -NL or -NL2 Relay Option.)

3.8.1

EPM 5300P Relay Overview

The EPM 5300P offers dry contact relay output capability. The EPM 5200P only offers KYZ pulse outputs and cannot be configured to trip contacts on events.

FAIL-SAFE MODE: The EPM 5300P -NL option gives the user an adjustable tripping bandwidth. The user specifies a range over which functions, such as frequency, phase relation and voltage, are acceptable. The relay releases during times of normal operation, and engages when functions are outside specified normal levels. The relay can be programmed to engage during normal operating conditions, and release outside specified normal range (particularly when power is lost). This is the fail-safe mode.

HYSTERISIS: The EPM 5300P -NL option also includes adjustable hysterisis. In addition to a time delay on activating any contact, the user may specify a lower level to release the relay, rather than releasing after the initial alarm point. This is ideal during load shedding when an alarm activates at a certain level and the user does not want to turn off the alarm until a much lower, safer level.

SETABLE DELAYS: After reaching the alarm point, a change in relay status may be delayed for 255 seconds. The user also has the option of allowing the device to change relay status without any delay. After the alarm condition passes, the relay can be stopped from returning to a normal condition for a programmable time. Each delay time is independent of one another.

AND/OR LOGIC: If several parameters are assigned to one relay, the user can trip the relay if all functions are out of limit (and programming), or if one function is out of limit (or programming). For example, if limits on Voltage, Kilowatts, and Phase Imbalance are programmed and tied to Relay 1, the user can either trip the relay if one function is out of limit, or if all functions are out of limit.

3.8.2

2 Relays & 1 KYZ Pulse Output -NL OPTION

The EPM 5300P's flexibility accesses a variety of relay options through the Programming

Mode (see programming sections). The relay option package consists of three relays: two can be dedicated to alarm or controlled through communication (or both) and one for KYZ pulse output.

If the relays are controlled through communication, there are two different modes:

• Lock ON: Relay will not be affected by any alarm condition.

• Lock OFF: Relay will not be affected by any alarm condition.

If the relays are used for communication and alarm, there are four different modes:

• Lock ON: Relay stays on regardless of any alarm condition.

• Lock OFF: Relay stays off regardless of any alarm condition.

• Free ON: Relay turns on unless other conditions force it off.

• Free OFF: Relay turns off unless other conditions force it on.

CHAPTER 5: OVERVIEW ACCESSING MAX/MIN VALUES

5.5

Accessing Max/Min Values

Max/min values represent the highest and lowest average demand over a user programmable time period known as the Integration Interval. The readings are calculated using a rolling average technique. Each second, a new reading is used to calculate the max/min; the last reading of the interval is dropped off. The highest max during an averaging period is stored until the user resets the max/min. This is similar to amp demand meters. It is commonly referred to as Thermal Demand.

To access a max/min value while displaying a desired measurement, press MAX/MIN/

VOLTAGE PHASE REVERSAL AND IMBALANCE CHAPTER 5: OVERVIEW

5.9

Voltage Phase Reversal and Imbalance

In a three-phase power distribution system, normal phase shift between each line is 120 °.

If the EPM 5300P detects an abnormality, it displays a message of PH. The EPM 5200P does not have this feature.

VOLTAGE PHASE REVERSAL: If there is an incorrect connection, such as mistaking line A for line B, a PH message appears. The correct sequence is a-b-c.

VOLTAGE PHASE IMBALANCE LIMIT: This is detected using the phase imbalance limit in the Programming Mode. The phase imbalance is expressed as a percentage, with 0% indicating a 120

° phase shift between each line. A PH message appears if the limit is exceeded.

Open Delta System Installation Programming

A special switch is used to indicate that the electrical system being monitored is a Threephase WYE or Three-Wire Open Delta System using the connection installation (see

Chapter 3). The switch is located in GROUP 0, FUNCTION 3, Pack 1, Switch D.

This switch should be set to UP only if the electrical system is a Three-Wire Delta or

Open Delta, using 2 PTs. Otherwise, the switch should be set to DOWN. Failure to select this switch results in Phase-to-Neutral readings, as well as incorrect power readings, with the 2PT connection.

Special Open Delta Connection Installation should be followed in the Installation and

Operation section (Chapter 3).

To print, access Mode 1 and Mode 2 (see Part I: Installation and Operation). Printing serial options should be disabled when using a multimeter communications connection RS485.

DISABLING PREVENTS:

1.

Printing through the keypad.

2.

Corrupting data at a computer terminal while multiple meters poll.

3.

Corrupting printing commands through communications.

This option connects a serial printer to the RS232 port and prints the data. Disable this feature when the meter is not using an RS232 port (i.e., when RS485 or DC outputs are being used).

Group 0, Functions 4–5—Time Delay for Relays 1 & 2 (Option – NL)

GROUP 0, FUNCTIONS 4–5 sets the time delay for Relays 1 and 2 between 0 and 255 seconds. This allows conditions (example below) to exist for a userspecified time period before the relay or alarm activates. If a time greater than 255 seconds is entered, the meter defaults to the maximum value of 255 seconds.

Example: If Relay 1 is set for 300 amps and the amps increase to 301, the Relay trips only after a programmed delay period. If the meter then measures 299 Amps, the Relay returns to its original position, after the programmed delay.

Scale Settings

Programming Group 1 – Voltage, Amp And Watt Scale Settings

The EPM 5300P and 5200P full scales will already be programmed if the order specified current and voltage transformer ratios. The meter label indicates any full scale setup.

Programming Group 1 contains voltage, amperage and full scale power selection, along with scale factor selection and decimal point placement.

The user can re-scale without removing the EPM 5300P for calibration. The 5300P has been calibrated at standard levels in GROUP 2. Mathematically convert any full scale ratios to those calibrated levels. If a different current or voltage transformer is used, program the primary value of its ratio. If necessary, convert the ratio to a secondary value of five amps standard current (1 amp is a special order) and 120V or 75V nominal voltage (options L only).

Formulas:

Primary

Secondary

x 120

V

Primary

Secondary x 75V

Primary

Secondary x 5A

It may be necessary to convert the full scale to a larger unit. There is a resolution limitation for all full scales of 2000. If a display reading exceeds 2000, it may be unstable and subject to zeroing problems.

Example: The full scale for a CT ratio of 3000/5 should be 03.00 kA.

When changing a PT or CT full scale, calculate the new watts full scale and make any necessary changes. The watts full scale will not auto range.

10.3 Group 1, Function 2

- SCALE SELECTION AND DECIMAL PLACEMENT FOR WATTS -

Programming GROUP 1 also provides decimal positioning for maximum resolution. The following examples assist in selecting the best decimal position for FUNCTION 2.

Shift the decimal left to increase resolution. Wattage should not exceed a numeral value of 2500. Shift the decimal one position right to decrease resolution.

Full Scale Wattage (FSW) is the product of FSV and FSA. For FSW for three phases multiply the FSW per phase by 3.

Example 1: Full Scale Voltage (FSV)=120 V

Full Scale Amperage (FSA)=5.00 A

FSW (one phase) =120 Vx5.00 A

FSW (one phase)=600 W

FSW (three phase)=600 Wx3 = 1,800 W

Here the FSW is too small a value for a Megawatt meter. FSW in the Kilowatt meter equals

1.800 KW. In FUNCTION 2, four 9s appear. Place the decimal point after the first digit. The user cannot change the four digits. The user can only move the decimal point placement.

Example 2: 480/120 PT, 1000/5 CT

FSV=480 V

FSA=1000 A

FSW (one phase)=480 V ⋅ 1000 A

FSW (one phase)=480,000 W

FSW (three phase)=480,000 W

3 = 1,440,000 W

FSW for a Kilowatt meter equals 1440. KW. FSW for a Megawatt meter equals 1.440 MW. In

FUNCTION 2 place the decimal point after the last digit for a Kilowatt meter and after the first digit for a Megawatt meter. It is important to note which type of bezel labeling you have when making this decision.

Example 3: 14.4 KV/120, 1000/5 CT

FSV=14.40 KV

FSA=1000 A

FSW (one phase)=14,400 Vx1000 A

FSW (one phase)=14,400,000 W

FSW (three phase)=14,440, 000 Wx3 = 43,200,000 W

FSW for a Kilowatt meter equals 43,200 KW. Here the FSW is too large a value for a

Kilowatt meter (the range is 000–2500). FSW for a Megawatt meter equals 043.2 MW. In

FUNCTION 2, place the decimal after the third digit.

In some applications where the load is normally very low, the watts resolution can be increased by moving the decimal point one position left.

WARNING—READ THIS SECTION CAREFULLY BEFORE PROCEEDING:

• Any rescaling, such as a change in a transformer ratio, can be accomplished in

GROUP 1. Calibration is not necessary.

• Meter calibration cannot be performed if the meter is installed for service. The sensing inputs must be connected to a power supply with variable voltage and separate current outputs.

• The calibration procedure requires highly accurate and stable input signals.

Incorrect readings result from improper calibration procedures. If unsure, return unit to the factory for calibration.

• BEFORE calibrating any channel, make a note of its Full Scale Setting (see Chapter

10). Set the Full Scale in accordance with Table 10-2 for calibration. Restore original Full Scale Setting when calibration is completed.

Groups 4, 5 and 6—Set Limits and Relays

The EPM 5300P -NL offers a comprehensive limit and set point functionality. The user can program above or below limits for every reading, including %THD. When a voltage or current measurement exceeds a particular value, the set limit is triggered and alerts the user. Each limit can trigger two internal Form C dry contact relays for alarm or secondary protection.

The EPM 5300P offers two set limit points available for each measured function: LM1 and

LM2. Each limit can be set at any desired level. Note: The EPM 5200P does not have limit setting capability.

CHAPTER 16: ETHERNET OPTION ETHERNET OPTION SETUP

Note

16.2 Ethernet Option Setup

This chapter covers the required steps to get the Ethernet Interface on-line and working.

There is only one method used to log into the Ethernet Server and set up the IP address:

• Network Port Login: make a Telnet connection to the network port (9999).

It is important to consider the following points before logging into and configuring the

Ethernet Interface:

• The Ethernet Interface’s IP address must be configured before a network connection is available.

• Only one person at a time may be logged into the network port. This eliminates the possibility of several people trying to configure the Ethernet Interface simultaneously.

16.2.1

Default IP Address

The Ethernet Interface ships with a default IP address set to 0.0.0.0, whish automatically enables DHCP within the Ethernet Interface.

Provided a DHCP server exists on the network, it will supply the Ethernet Interface with an

IP address, gateway address and subnet mask when the Ethernet Interface boots up. If not DHCP server exists, the Ethernet Interface will respond with a diagnostic error: the RED

Diagnostic LED blinks continuously and the GREEN Status LED blinks five times.

16.2.2 AutoIP

Auto IP allows an Ethernet Interface to obtain an address in a network that does not have a DHCP server. (Windows 98 and 2000 also support AutoIP.)

AutoIP assigns a random valid address to the Ethernet Interface in the range of 169.254.x.1 to 169.254.x.1 (x can be between 0 and 255). This range of IP addresses is not to be used over the Internet. If the Ethernet Interface has not been configured manually and cannot find a DHCP server, it automatically chooses an address from the reserved range. The

Ethernet Interface then uses the Address Resolution Protocol (ARP) to send out a request asking if any node is using that address. If another node is using the same address, the

Ethernet Interface assigns another IP address, reboots and repeats the sequence.

AutoIP-enabled Ethernet Interfaces are constantly looking for DHCP servers. If a DHCP server becomes available on the network, the AutoIP-enabled Ethernet Interface switches to the DHCP server-provided address and the unit reboots. If the DHCP server exists but denies the Ethernet Interface an IP address, the Ethernet Interface does not attach to the network, but waits and retries.

AutoIP allows a small network of AutoIP-enabled devices to be set up without any need for a DHCP server or static IP addresses.

AutoIP can be disabled be setting the IP address to 0.0.1.0. The 1 in the third octet is the disabling factor.

Note

ETHERNET OPTION SETUP CHAPTER 16: ETHERNET OPTION

16.2.3

Setting the IP Address

The Ethernet Interface’s IP address must be configured before a network connection is available. If the IP address was not set automatically via DHCP, set it now using a network and the setup (configuration) menu.

Network Port Login

The ARP method is available under UNIX and Windows-based systems. The Ethernet

Interface will set its address from the first directed TCP/IP packet it receives.

ARP on UNIX

On a Unix host, create an entry in the host’s ARP table using the intended IP address and the hardware address of the Ethernet Interface, which is found on the product label.

arp –s 191.12.3.77 00:20:4a:xx:xx:xx

ARP ON WINDOWS

In order for the ARP command to work on Windows, the RP table on the PC must have at least one IP address defined other than its own. If the ARP table is empty, the command will return an error message. Type ARP –A at the DOS command prompt to verify that there is at least one entry in the ARP table.

If the local machine is the only entry, ping another IP address on your network to build a new entry in the ARP table; the IP address must be a host other than the machine on which you are working. Once there is at least one additional entry in the ARP table, use the following command to ARP the IP address to the Ethernet Interface: arp –s 191.12.3.77 00-20-4a-xx-xx-xx

Telnet to Port 1

Now open a Telnet connection to Port 1. The connection will fail quickly (3 seconds). But the Ethernet Interface will temporarily change its IP address to the one designated in this step. telnet 191.12.3.77 1

Telnet to Port 9999

Finally, open a Telnet connection to port 9999 and set all required parameters.

telnet 191.12.3.77 9999

This IP address is temporary and will revert to the default value when the Ethernet

Interface’s power is reset, unless you log into the Ethernet Interface and store the changes permanently.

16.2.4 Network Configuration

Certain parameters must be configured before the Ethernet Interface can function on a network. The Ethernet Interface can be locally or remotely configured using the following procedures:

16–120 EPM 5300 SERIES ADVANCED POWER METERS – INSTRUCTION MANUAL

CHAPTER 16: ETHERNET OPTION

Note

ETHERNET OPTION SETUP

Use a Telnet connection to configure the unit over the network. The Ethernet Interface’s configuration is stored in nonvolatile memory (NVRam) and is retained without power. The configuration can be changed at any time. The Ethernet Interface performs a reset after the configuration has been changed and stored.

As mentioned above, to configure the Ethernet Interface over the network, establish a

Telnet connection to port 9999. From the Windows Start menu, click Run and type the following command, where x.x.x.x is the IP address and 9999 is the Ethernet Interface’s fixed network configuration port number.

telnet x.x.x.x 9999

Be sure to include a space between the IP address and 9999.

16.2.5

Configuration Parameters

After entering Setup Mode (confirm by pressing Enter), you an configure the parameters by entering one of the numbers on the Change Setup Menu, or you can confirm default values by pressing Enter. Be sure to store new configurations when you are finished. The

Ethernet Interface will then perform a power reset.
