Applications
SMART GRID READY
With the increasing push for advanced monitoring, reduction
of outages and the need to facilitate two-way communications
between supply and the distribution network, the U-Series
solid dielectric recloser is ready to be integrated into your
Smart Grid solution.
LOOP AUTOMATION
Restoring supply to your customers in the shortest possible
time is the focus of Recloser Solutions’ Loop Automation
Scheme.
The Loop Automation Scheme reconfigures protection
settings, sectionalises faults, minimises affected areas, and
restores network supply without the need for communications
or operator intervention, using standard recloser features.
A network affected by an outage is automatically reconfigured
to provide power to the unaffected area when an additional
supply is available. Using a combination of Feeder, Mid-Point
and Tie Reclosers to protect, sectionalise faults and minimise
affected areas, Loop Automation is a Distribution System
Automation Scheme designed to restore supply to customers
in the shortest possible time.
AUTOMATIC CHANGEOVER (ACO)
The Automatic Changeover (ACO) system uses primary &
alternative supplies, master & slave reclosers and fast
communications to ensure that supply is always available for
a critical load in the event of a power failure.
Using a number of different set-ups, including Break-BeforeMake and Make-Before-Break, allows the system to be
configured to the exact specifications required for the critical
load. The system can even be set up for one-way or two-way
switching to ensure power is always available to your critical
systems.
OPERATION AS A SECTIONALISER
Reclosers and sectionalisers work together to further improve
feeder reliability. Using a separate RL-Series LBS/
Sectionaliser, as part of a feeder automation network, detects
fault passage and automatically isolates faulty sections of a
network in conjunction with upstream recloser operation. To
accomplish this it senses the three-phase current and voltage
to count the number of recloser trip operations. When the
pre-programmed number of recloser operations is reached,
the controller opens the sectionaliser during the recloser
dead time to isolate the downstream fault.

Introduction & Benefits
The U-Series & W-Series solid dielectric
Automatic Circuit Recloser (ACR)
represents Schneider Electric’s commitment
to improved products and ongoing product
development. Providing the features of a
traditional recloser, plus the benefits of
up-to-date design optimised for automation,
remote control and monitoring, now or in the
future.
REDUCED PURCHASE COST
¢ Fully Intergrated: No requirement for additional RTU, power supplies, batteries
or enclosures. The Remote Terminal Unit (RTU) and a range of communication
ports are included in the standard equipment.
REDUCED INSTALLATION COSTS
¢ Simple Commissioning: Configuration of the unit is from the WSOS Software or
the Operator Interface (O.I.).
¢ All key components required for installation are included
The U-Series & W-Series development was
driven by customer demand for improved
return on capital investment in the
distribution network. After careful evaluation
of customers’ needs, the U-Series was
developed to achieve optimum performance
and reliability, making use of the latest
available technology in solid dielectrics,
vacuum interruption and microelectronics.
The result is a world-class product of which
we are justly proud.
In the past, distribution equipment such as
reclosers have been purchased only to
support load growth. Today, your
customers, the electricity consumers, are
demanding reduced outages and lower
tariffs. At Schneider Electric we are
continually working to provide the advanced
equipment needed for tomorrow’s
competitive electricity distribution system.
By using our technologically advanced
equipment, operating costs will be reduced
and capital works can be deferred through
better management of existing plant. In
addition, outages causing lost revenue will
be reduced.
In addition to automatic circuit reclosers, the
Schneider Electric family of switchgear
includes remotely controlled and monitored
pole-mounted load break switches and
sectionalisers, as well as remote control and
monitoring software.
¢ Pole mounting brackets are provided in the standard package. An optional
Voltage Transformer (VT) for auxiliary supply is available.
¢ Schneider Electric ACRs are ideally suited as low-cost feeder circuit breakers in
outdoor primary substations. In this application, connection into the substation
control system is simple and low cost.
REDUCED OPERATING COSTS
¢ Reduce Equipment Damage: The integral protection relay provides fast isolation
of faults.
¢ The recloser constantly monitors line current and voltage without the need for
additional measurement devices. This data can then be used for forward
planning and optimisation of existing feeders.
¢ Long lifetime, low maintenance equipment reduces lifetime cost.
DSA/SCADA COMPATIBILITY
When used with a compatible Distribution System Automation (DSA) or SCADA
system, Schneider Electric ACRs support remote control and monitoring to provide
the following advantages:
¢ Reduced Travel Time for Line Crews: Information on fault current and recloser
status values transmitted to system control allows fast location of the faulted line
section.
¢ This same information allows informed remote switching, reducing the affected
area and quickly restoring supply.
¢ ACRs can be configured and settings managed from system control, without
technicians having to visit each individual recloser in the field, with a consequent
reduction in travelling time and improved system integrity.
INCREASED CUSTOMER SATISFACTION
¢ Reduced Customer Minutes Lost: Supply can be quickly restored to fault-free
areas.
DEFERRED CAPITAL WORKS
¢ Remotely controlled and monitored reclosers give an improved knowledge of a
system and provide better system control. Feeder and substation load can then
be remotely managed, improving utilisation of existing plant. Purchase of new
plant can then most likely be deferred for a considerable period of time.
The Schneider Electric Switchgear and
Controller product family is a complete
solution for Distribution System Automation.

U-Series ACR Overview
The U-Series ACR uses vacuum
interrupters, contained in epoxy bushings,
eliminating the need for insulants like oil and
gas.
The mechanism is enclosed in a 316
stainless steel tank with a stainless steel lid.
The U-Series circuit breaker is controlled and monitored by either the COMPACT or
ULTRA ADVC Controller (ADVC).
Enclosed in a 304 (COMPACT) or 316 (ULTRA) grade stainless steel enclosure the
ADVC provides an electronic controller with Operator Interface (O.I.) that monitors
the circuit breaker and provides protection, measurement, control and
communication functions. Connected via a control cable, the Switchgear and ADVC
can form a remotely controlled and monitored ACR.
1
The switchgear is operated by a magnetic actuator which produces an opening and
closing action. Switching occurs when a controlled pulse is sent through the open/
close actuator from storage capacitors in the ADVC. When closed, the switch is
latched magnetically. Spring loaded pushrods provide contact loading on the
interrupters.
2
A Current Transformer (CT) and a Capacitive Voltage Transformer (CVT) are
moulded into the CT-housing. These are monitored by the ADVC for protection,
remote monitoring and display.
9
10
3
An auxiliary voltage supply of 115/230 volts AC is required to power the control unit.
Where this is inconvenient, an additional voltage transformer can be provided.
The recloser is supplied with copper stems or optional cable clamp connectors.
Mounting brackets for lightning arresters are optionally available.
The switchgear contact position is shown by a large, clearly visible external pointer. A
hookstick can be used to engage the manual trip ring to trip and lockout the recloser
from the ground. The mechanical trip ring has two positions: UP position allows for
normal operation, and in the DOWN position the recloser is tripped and both
mechanically and electronically locked open.

The ADVC interfaces to the switchgear via the control cable and connects to the
Switch Cable Entry Module (SCEM) in the base of the tank via a covered plug/socket
sealing arrangement on both the ADVC and the Switchgear. The SCEM uses
non-volatile memory to store all relevant calibration data, ratings and number of
operations. The SCEM also provides the first stage of electrical isolation and
shorting electronics to short the CTs and CVTs in the event the control cable is
disconnected while current is flowing through the switchgear.

ADVC Controller Series
Advanced protection, data logging &
communications capabilities are made
possible by the technology housed in the
ADVC Controller.
With a cubicle designed to minimise temperature rise from solar heating, the 304
(COMPACT) or 316 (ULTRA) grade stainless steel enclosure is used to mount the
Control And Protection Enclosure (CAPE), Power Supply Unit (PSU), customer
accessories and Operator Interface.
It has been designed especially for outdoor
pole mounted operation and is typically
mounted low on the pole for ease of access
by operation personnel.
Batteries are carefully located underneath these modules to help avoid overheating
so that a battery life of up to 5 years1 can be achieved. A vandal resistant lockable
stainless steel door, sealed with a rubber gasket, provides access to the Operator
Interface. Vents are screened against vermin entry and all electronic parts are
enclosed in a sealed die-cast enclosure which protects them from entry of moisture
and condensation ensuring a long lifetime.
The ADVC Controller Series incorporates the functions of a multi-function protection
relay, a circuit breaker controller, a metering unit and a remote terminal unit.
The COMPACT Cubicle is suitable for temperatures from -10°C to 50°C , while the
option of a battery heater in the ULTRA Cubicle extends its operating temperature
range from -40°C to 50°C.
A built-in microprocessor controlled power supply provides uninterrupted operation
of not only the circuit breaker and controller, but also the communications radio or
modem. These accessories are connected to a built-in user progammable radio
power supply. Therefore no other power supplies are required for connection into
your SCADA or Distribution Automation System.
Due to careful design the efficiency of all parts is extremely high, allowing a battery
hold up time of up to 44 hours2. The architecture used has the advantage that the
circuit breaker operation is independent of the high voltage supply, relying on a set of
capacitors charged by the auxiliary supply.
Due to sophisticated power supply management techniques, a circuit breaker
operation is always guaranteed when attempted and alarms are raised over the
telemetry when auxiliary power is lost.
Communications equipment can be mounted within the ADVC Controller cubicle. A
V23 FSK modem, RS232, RS485 and Ethernet TCP/IP are provided as standard to
support all of your communications needs.
The ADVC Controller Series is available in two models:

TELEMETRY INTERFACE
The Schneider Electric ACR can be interfaced to your SCADA system either through
its built-in V23 modem and a radio, or its RS232 ports and a modem of your choice.
RS485 and Ethernet TCP/IP are also available. A variable voltage uninterruptable
power supply is included for the radio or modem, which can be mounted inside the
communications cubicle. Many telemetry protocols can be supported such as DNP3
and IEC 60870-5-101.

flexVUE Operator Interface
Customising the operator interface to suit
your unique applications has never been
easier.
The flexVUE Operator Interface uses Light Emitting Diodes (Lamps) and an LCD
display to communicate the system status to a local operator. Operator actions that
are performed on a regular basis can be mapped to 12 dedicated buttons on the
interface.
Each of these buttons also have a lamp to indicate the ON/OFF state of each action.
Together with the 20 status lamps the panel provides no less than 32 three-colour
LEDs that display the state of the controller and overhead system. On the interface,
the action buttons are grouped together and referred to as Quick Action Keys. The
status LEDs are also grouped together and referred to as Status Lamps.
Every controller is programmed with a standard configuration of Status Lamps and
Quick Action Keys: text labels are used to mark the function of each. These labels
are inserted into special pockets within the flexVUE Operator Interface and can be
changed in the field if required.
A graphical panel configuration tool is provided as part of the WSOS 5 software
package that will allow full customisaiton of the flexVUE Operator Interface, if
required. With the the tool you can create your own logic functions driving the Status
Lamps, as well as change the actions linked to each Quick Action Key. New labels
can be printed from the WSOS template using standard office stationery, cut to size
and inserted into the controller.

WSOS offers a quick, easy way to configure the protection groups.
Automatic Protection Group Selection is used to change the protection group
depending on the direction of power flow. This allows the recloser to be correctly
graded with devices downstream regardless of the power flow direction.
LOSS OF PHASE
Loss of phase protection trips the recloser if phase-earth voltage on one or two
phases falls below a set voltage threshold for a set length of time.
¢ Threshold voltage range:
2 - 15kV
¢ Voltage resolution:
1V
¢ Time range:
0.1 - 100 sec
¢ Time resolution:
0.1 sec
LIVE LOAD BLOCKING
Live load blocking prevents a recloser from closing if any of the load side terminals
are live.
¢ Live Load Threshold Voltage range:
2 - 15kV
DEAD LOCKOUT
Dead lockout prevents a reclose unless one or more of the source side or load side
terminals are live. If all terminals are dead then the controller goes to lockout.

Advanced Protection Features
DIRECTIONAL BLOCKING
Directional blocking is a protection feature that restricts tripping on faults to a
designated side of the recloser. It prevents nuisance tripping if particular network
conditions are causing “false” earth faults. In radial systems, Directional Blocking
prevents nuisance tripping by blocking faults in the source direction and only
responding to faults in the load direction.
DIRECTIONAL PROTECTION
Distinct protection for faults in the forward and reverse direction. A forward fault may
use a different time-current curve and settings to a reverse fault (i.e. these are
individually selectable). Both the forward protection and reverse protection are
operating at the same time. This is an additional protection feature.
SEQUENCE COMPONENTS
Negative, positive and zero phase sequence currents and voltages can be
monitored and logged.
In addition, the negative phase sequence current protection can be used for
detection of low-level phase-to-phase faults in the presence of high level threephase loads. Inverse Time, Definite Time and Instantaneous operation is available.
¢ Setting current range: 10 - 1260 A
SEQUENCE COORDINATION
Sequence coordination allows a recloser to coordinate its trip sequence with
another recloser downstream.
UNDER / OVER FREQUENCY PROTECTION
This feature trips the recloser when the system frequency exceeds the under and
over frequency trip threshold values. Frequency tripping range: 45 - 65 Hz
¢ Frequency calculation:
Once / cycle over a 2 cycle period
2 - 1000

Measurement Features
VOLTAGE & CURRRENT
True RMS voltage is measured on the three I-Side terminals. A user configured
threshold indicates live terminal. RMS current is measured on three phases (reading
2 - 630A).
Optional external Capacitive Voltage Transformers (CVTs) can be fitted to measure
the voltage on the other three (X-Side) terminals. External CVTs can be purchased at
the time of your order or can be added to an existing installation when required. The
external CVTs are mounted onto a cross-arm adjacent to the recloser and the
secondaries are connected to the SCEM card located in the base of the recloser.
REAL POWER (SIGNED OR UNSIGNED)
Real power is determined by multiplying the line voltage and line current in real time
and averaging over 2 seconds (accuracy ±5% of reading, within limits of V and I
above).
POWER & POWER FACTOR
The ADVC Controller measures kW, kVA, kVAr and powerfactor on a per-phase
basis.
The power factor of the line is determined from the line voltage and the line current
phase relationship and the previously calculated real power (accuracy ±5% of
reading, within limits of V and I above).
DEFAULT HISTORICAL MEASUREMENTS
Power flow is integrated over 5, 15, 30, or 60 minute intervals (kWh) and recorded for
two months at the default setting. This can be viewed on the operator control panel,
computer, or compatible SCADA system. Additionally, data can be uploaded into a
portable computer or a compatible SCADA system.
CONFIGURABLE HISTORICAL MEASUREMENTS
Average demand profiles may be configured using WSOS. Customised
configuration enables the user to specify only the parameters that are required,
negating unnecessary information capture. Parameters such as line voltages and
currents, power, kWh, battery voltage and cubicle temperature can be recorded in
intervals selectable between 1 and 1,440 min.
EVENT HISTORY

Harmonic analysis
£
The Supply Outage Measurement feature utilises built-in recloser features to
record the number and duration of outages. These statistics are recorded in
the controller and are available to the Utility to help calculate system outage
customer minutes.
The controller records:
- cumulative total number of outages,
- cumulative total outage duration, and
- the time and duration of each outage event in the Event Log.
These records are accessible to the user and can be retrieved using the
operator control panel, WSOS or a SCADA System.
¢ Harmonic analysis:
£
Harmonics 2 to 16 and the Total Harmonic Distortion (THD) are calculated over
a 80 ms period for four currents, six line-line voltages and six line-earth
voltages. These harmonics are available via WSOS.
¢ Waveform capture:
£
£
£
Waveform capture
16
Based on an user defined trigger, the ADVC captures and stores in non-volatile
memory scaled raw data (10 x 3200 samples per second) of the six line-earth
voltages and four currents for a predefined time window either side of a
user-defined trigger.
The user can configure a pre and post trigger time ratio for data to be stored.
This defaults to 50% pre-trigger and 50% post-trigger.
The captured data can be uploaded at anytime in COMTRADE (IEEE Std
C37.111-1999) format via WSOS.
