Overview of ABB TCS Auxiliary Relay:

The ABB TCS Auxiliary Relay is a specialized component designed to enhance the effectiveness of trip circuit supervision in electrical systems. It acts as a pivotal element in the supervision process, providing advanced monitoring capabilities to ensure the reliability and proper functioning of protective circuits. ABB’s TCS relay is engineered with advanced features and technology, meeting industry standards and offering a comprehensive solution to efficiently supervise trip circuits, contributing significantly to the safety and efficiency of electrical infrastructure.

 Features Of ABB Tcs Trip Circuit Supervision

• Delaying the operation to prevent false signals, such as during circuit breaker operations.
• Complete range of rated voltages either AC or DC
• Utilizing low-level measuring currents allows for application in circuits that are sensitive or possess high resistance.
• It’s feasible to achieve galvanic isolation between the auxiliary power source and the monitored circuit.
• Operation indication by a single dual-colour LED
• Very low burden on the auxiliary source
• Continuously supervising the entire trip circuit without being reliant on the circuit breaker’s position.
• Identifies issues within the monitored circuits, such as voltage loss, circuit interruptions, deterioration of contacts, and increased resistance in wires, contacts, and coils.

Application Of ABB TCS Trip Circuit Supervision Relay 

In a protection system, the proper functioning of a circuit breaker’s tripping mechanism holds significant importance. If there’s an interruption in the trip circuit, it could lead to a situation where a potential network fault remains connected, requiring other protection mechanisms further up in the power system to clear the fault. The supervision function becomes especially crucial when there’s reliance on a single tripping coil, and the circuit breaker’s tripping action is essential. This scenario commonly occurs in critical settings such as generator circuit breakers or other pivotal circuit breakers within distribution networks.

Supervision Relay

The TCS supervision relay is designed for continuous monitoring of a circuit breaker’s trip circuit. It provides an alarm for various issues including loss of auxiliary supply, faults in the trip coil or its wiring, irrespective of the breaker’s position, faults in the breaker’s auxiliary contacts, and faults within the supervision relay itself. Trip circuit supervision is critical as its failure might lead to the persistence of a network fault, necessitating intervention from upstream protection mechanisms.

Under normal circumstances, the LED indicator shines green, and the output relays remain engaged. However, in the event of a fault, the supervision relay triggers (disengages) after a 0.6-second delay, turning the indicator LED red.
