Pama pami programmable features features active contact function for both phase sequences with two relays detects phase sequence phase failure phase regeneration and phase loss in three phase mains.

Can be accomplished by using the diagram below. If a phase failure occurs on l1 the control relay cr c ontacts change state. Cade simu technology channel 22 689 views 10 21. The output relay is energized when all three phase voltages are present and the phase conditions voltage and phase sequence are correct.

Paha pahi 4 wire. The k8ak ph1 output contacts are normally operative. Must watch this if you want to know how to wire phase failure relay phase monotoring relay and a direct on line starter. How to wire a xj3 d brand chint phase failure and phase sequence protective relay device duration.

How to wire a phase sequence. Wiring example timing charts phase sequence and phase loss operation diagram note. Note due to wrong connection done the above diagram is update in the above diagram i shown the complete method of wiring or connection of phase failure relay diagram with circuit breaker cont actor overload relay push button switches and electric motor however lets talk about this step by step. If a phase failure occurs on l2 or l3 the shunt trip coil will draw power from l1 through the control relay cr contacts and phase failure relay contacts which will c hange state upon detecting a phase failure.

Cade simu technology channel 28 286 views. The phase failure relay has a fixed time delay to prevent faulty energization and de energization caused by short interferences. The relay will not operate if the input voltage drops below 70 of the minimum input value because l1 and l2 are also used to provide power.
