6kV 6.3kV 12.5kV 15kV Three-Phase Smart recloser/reclosure Source Manufacturer

 Overview

The circuit breaker is controlled and monitored by either the COMPACT or ULTRA PowerLogic ADVC Controller (ADVC). Enclosed in a stainless steel or mildsteel enclosure coated with zinc rich epoxy and special powder paint system PowerLogic 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 PowerLogic ADVC can form a remotely controlled and monitored 

Function

• Magnetic Actuator Operation: The switchgear is driven by a magnetic actuator for opening and closing actions. Controlled pulses from storage capacitors are sent to the actuator to enable switching. When closed, the switch is magnetically latched in position.

• Integrated Sensing and Monitoring: The epoxy pole is molded with built-in Current Transformers (CTs) and dual Capacitive Voltage Transformers (CVTs), which are continuously monitored by the PowerLogic ADVC system for protection, remote monitoring, and status display.

• Flexible Power and Interface Configuration: The control unit requires a 115/230 V AC auxiliary power supply, with an optional voltage transformer available for power supply where needed. Terminal nemapad connectors or optional cable clamps are provided. Optional surge arrester mounting brackets and a clearly visible external pointer for contact position indication are available.

• Safe Manual Trip and Interlocking: Equipped with a manual trip lever operable from ground level, which simultaneously opens and locks out the switch. The lever position is communicated to the PowerLogic ADVC via a micro-switch and electronically interlocks both local and remote closing operations.

• Intelligent Interface and Safety Isolation: The PowerLogic ADVC connects to the switchgear via a control cable linked to the Switch Cable Entry Module (SCEM). The SCEM stores calibration data, ratings, and operation counts, and provides electrical isolation with shorting circuits to automatically short CTs and CVTs if the control cable is disconnected while the switchgear is energized.

Rated Short-Circuit Breaking Current includes 8kA, 12.5kA, 16kA, 20kA, 25kA, 31.5kA and customization is available.

ADVC Overview

Advanced protection, data logging, and communications capabilities are made possible by the technology housed inthe PowerLogic ADVC. 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.

ADVC Functions
With a cubicle designed to minimize temperature rise from solar heating, the stainless steel or mildsteel enclosure, or enclosed in a mild steel enclosure coated with zinc rich epoxy and special powder paint system is used to mount the Control and Protection Enclosure (CAPE), Power Supply Unit (PSU),customer accessories, and Operator Interface.The PowerLogic ADVC Series incorporates the functions of a multi-function protection relay, a circuit breaker controller, a metering unit, and a remote terminal unit.Batteries are carefully located underneath these modules to help avoid overheating so that a battery life of up to 5 years(1) can be achieved. A vandal resistant lockable stainless steel or mild steel door, sealed with a rubber gasket,provides access to the operator interface. Vents are screened against verminentry and the electronic parts are enclosed in a sealed die-cast enclosure which helps protect them from the entry of moisture and condensation for a long lifetime.
The COMPACT cubicle is suitable for temperatures from -10 to 50 °C, while the option of a battery heater in the ULTRA extends its operating temperature range from -40 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 programmable 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 the parts is high, allowing a lead-acid battery hold-up time of up to 46 hours(2). The LiFePO4 Battery of the controller can offer 43 hours of hold up time(3).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 will operate when attempted, and alarms are raised over the telemetry when auxiliary power is lost. Communications equipment can be mounted within the PowerLogic ADVC cubicle. RS-232 and Ethernet TCP/IP are provided asstandard to support your communications needs.

ADVC Specifications

The PowerLogic ADVC series is available in two models:
ULTRA
COMPACT
The following table outlines some of the differences between the two models:

(1) LiFePO4 battery option is available only in ultra version of PowerLogic ADVC.

(2) PowerLogic ADVC with LiFePO4 batteries are suitable for environment with ambient temperature in the range of -20 to 50 °C.
