If a phase failure occurs on l1 the control relay cr c ontacts change state.
Can be accomplished by using the diagram below.
Connection diagram 3 phase sequence control phase monitoring relay 3 wire.
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.
Phase loss cannot be detected on the load side because.
The output relay is energized when all three phase voltages are present and the phase conditions voltage and phase sequence are correct.
The phase failure relay monitors phase sequence phase break and undervoltage.
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.
