Nke PMSet U-Series circuit breaker na-enye ihe nrite na-eji ya COMPACT ma ọ bụ ULTRA PowerLogic ADVC Controller (ADVC). Nke a na-ekwu anya n'ụzọ stainless steel ma ọ bụ mildsteel coated with zinc rich epoxy and special powder paint system. PowerLogic ADVC na-enye electronic controller with Operator Interface (O.I.) nke na-enye ihe nrite nke circuit breaker na-enye protection, measurement, control, and communication functions. Na-enyere ha site na control cable, switchgear and PowerLogic ADVC nwere ike ịbụ ACR nke na-enye ihe nrite n'ụzọ.

Switchgear na-egosi n'ụzọ magnetic actuator nke na-enye opening and closing action. Egosi na-eme ka ọ bụla ịchọpụta controlled pulse na-enwe open/close actuator from storage capacitors in the PowerLogic ADVC. Ka ọ bụla ịchọpụta, switch na-enye latched magnetically. Spring loaded push-rods na-enye contact loading on the interrupters. A Current Transformer (CT) and two Capacitive Voltage Transformer (CVT) na-enwe na epoxy pole. Ha na-enye ihe nrite nke PowerLogic ADVC for protection, remote monitoring, and display. Auxiliary voltage supply of 115/230 V AC nwere ike ịbụ ihe nrite nke control unit. Ebe ọ bụghị dị mma, an additional voltage transformer nwere ike ịbụ. Recloser na-enye terminal nemapad connectors ma ọ bụ optional cable clamp. Mounting brackets for surge arresters na-enye optionally available. Switchgear contact position na-enwe na large, clearly visible external pointer. 
Main tank na-enye manual trip lever nke na-enye ihe nrite nke ground level by a hook stick which performs open and lockout simultaneously. Mechanical lever electronically inhibits both local and remote closing. Position of the lever na-enye ihe nrite nke PowerLogic ADVC by an associated micro-switch. Manual trip ring remains in the down position until physically returned to the normal position by the operator. PowerLogic 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 PowerLogic ADVC and the switchgear. SCEM uses non-volatile memory to store the relevant calibration data, ratings, and number of operations. SCEM also provides the first stage of electrical isolation and shorting electronics too short the CTs and CVTs in the event the control cable is disconnected while current is flowing through the switchgear.

Advanced protection, data logging, and communications capabilities na-enye ihe nrite nke technology housed inthe PowerLogic ADVC. Onye na-enye ihe nrite na-enye ihe nrite nke outdoor pole mounted operation and is typically mounted low on the pole for ease of access by operation personnel.

ADVC Fankshi
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.
