Phase Sequence Relay Working Principle

It works on the principle of an electromagnetic attraction. 51 2 negative sequence time overcurrent relay acted. The phase sequence indicator or phase sequence checker for a three phase supply is a device used for testing the three phase sequence of a supply in an electrical circuit or at the input of the electrical motors such as a three phase induction motor a three phase energy meter etc.

Generally negative sequence relays are having two stage of tripping.

Phase sequence relay working principle.

Ansi code for negative sequence relay. Working principle of relay. Working principle of relay. Negative sequence relay definition.

Phase sequence indicators can be classified into two types. Induction relay torque equation. The negative sequence relay protects the generator and motor from the unbalanced load which mainly occurs because of the phase to phase faults. Types of phase sequence indicators.

When the circuit of the relay senses the fault current it energises the electromagnetic field which produces the temporary magnetic field. This magnetic field moves the relay armature for opening or closing the connections. In induction relay torque equation two magnetic fluxes φ1 and φ2 differing in time phase penetrate through a disc. The small power relay has only.

These alternating fluxes induce emfs e1 and e2 in the disc which lag their respective fluxes by 90. The phase sequence meter is used for the detection of phase sequence in three phase circuits and there are different types of phase sequence indicators that are as follows. What is a phase sequence meter or indicator and its working principle. The first stage tripping is given to the grid circuit breaker as the grid is infinite loads the second stage of tripping will be given to the generator circuit breaker.

A relay which protects the electrical system from negative sequence component is called a negative sequence relay or unbalance phase relay.
