When a system has too many radial lines protection using time delay overcurrent relay becomes impractical. This problem can be solved to an extent by using distance relays. Distance relays uses voltage and current to calculate the. Distance relay protection has been defined as a part of relay protection in power systems that detects and isolates faults based on the distance between the relay and fault points. Unlike overcurrent relays, which only respond to the magnitude of current, a distance relay measures the impedance of. Such relays are called Distance Relays or Impedance Relays. In an impedance relay, the torque produced by a current element is opposed by the torque produced by a voltage element. The relay will operate when the ratio V/I is less than a predetermined value. The voltage transformer measures the voltage across the protected equipment, while the current transformer measures the current flowing through it.

This article describes the anti-pumping relay, its definition, function, and circuit diagram. In a circuit breaker it is desired that when close and trip operation is performed on the circuit breaker with the closing coil energized, the subsequent closing operation should be prevented. So let's. Anti-Pumping relay is nothing but a NO contact, which means when the circuit breaker in closed condition the relay will be as NO point and if the circuit breaker in open condition the relay will be as NC Condition. The anti-pumping relays is connected in series with the circuit. An anti pumping relay (also called antipumping relay or Y-relay and ANSI 94 Trip or Trip-Free Relay) is a protective device that prevents a circuit breaker from closing repeatedly when a continuous close command is present. In simple terms, it stops your circuit breaker from “pumping” – which means. Anti-pumping relays are used in circuit breakers to prevent the breaker from closing unexpectedly after tripping. If the TNC switch fails (Trip normal close) or there is any problem with the CB (circuit breakers) closing circuit, the continuous CB (circuit breakers) close command can be extended to. Why is the Anti-Pumping Relay Used? A circuit breaker is a very important equipment for a high-voltage power system. It protects the system from high current or voltage during a faulty condition.
