Protection CTs for Metering
Protection CTs for Metering
(OP)
Greetings
We plan to pull out the metering data from protection relays on one of our project. Protection class CTs will be used as we need them for different protection function.
Can any advise if it is OK to get energy data (kVA, kW, KVAR) through protection relays when the input to the relays is Protection class CTs.
Thanks

RE: Protection CTs for Metering
The protection functions of the relay are not impacted one way or the other by your use of this data.
FWIW, we do this all the time for substation automation and SCADA.
