Distribution Capacitor Bank
Distribution Capacitor Bank
(OP)
I retrieved some recloser data yesterday for one of the feeders. The data was showing
Phase A: PF=0.95, kW=258, kvar=85, KVA=269
Phase B: PF=0.56, kW=237, kvar=-346, KVA=421
Phase C: PF=0.51, kW=213, kvar=-356, KVA=416
The power factor on b and c phases were of some concern, and was considering a cap bank. What size cap bank would be ideal for this case. I was thinking of a 300 KVAR bank. I have never dealt with capacitor banks on the distribution feeder level, so any of your input is appreciated.

I agree with David Beach that you should verify the connections are correct and the controller is properly configured.
If the pf is truly leading, adding caps is only going to make it worse.

A blown fuse on an existing cap bank really does sound like a reasonable problem. Could it be a blown fuse on one of the metering PT's?
In any case, the imbalance of the system measured by the meter would indicate the metering is wrong.
