We want to know the order or sequence of voltages being produced by the generator and to make sure that the system has the same phase sequence before connecting the two.
Phase sequence relay connection diagram.
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.
Therefore you should banish clockwise and counter clockwise from your terminology if you want to effectively communicate phase sequence information with someone else.
If a phase failure occurs on l1 the control relay cr c ontacts change state.
How to wire a phase failure relay device phase sequence.
It reveals the components of the circuit as simplified shapes and also the power and signal connections in between the tools.
Can be accomplished by using the diagram below.
Connections terminal diagram note.
The relay will not operate if the input voltage drops below 70 of the minimum input value because l2 and l3 are.
The k8ak ph1 output contacts are normally operative.
Use the recommended ferrules if you use twisted wires.
The k8ds ph1 output contacts are normally operative.
Use the recommended ferrules if you use twisted wires.
Wiring example timing charts phase sequence and phase loss operation diagram note.
A wiring diagram is a simplified traditional pictorial depiction of an electrical circuit.

How to wire a phase sequence.
Wiring example timing charts phase sequence and phase loss operation diagram note.
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.
The relay will not operate if the input voltage drops below 70 of the minimum input value because l1 and l2 are.
