Thank you, bosss

[@srinivasvivek5145]

Sir, please explain, that shall i inject in only one phase at a time or shall we can inject 3 phase, if inject one phase remaining both phases current and angle should be zero, but operating current in one phase only, then how we would know if any current angle change in 3 phases at a time..

[@baranitech1026]

IF INJECT ON PHASE IN TWO CT REMAIN ALL CT WILL BE ZERO. SO THE DIFFERENTICAL VALUE WILL PICKUP FOR ONLY ONE PHASE AND IT WILL SEE FOR THAT PARITICULER PHASE TWO CT. THANK YOU.

[@vijayvana2346]

Whether same procedure should be followed for every phase of each bay. Kindly clear.

I have a question regarding pcm600
How do we add logic for scada command
And if the breaker , disconnector command is given through hmi button does one has to build logic for it or is it internal
If it's internal.. Does it check the conditions for close enable (CBXCBR1) automatically before executing the command

[@baranitech1026]

it has internal and CBXCBR1 block will check internal for close enable.
