Need PF (power factor) meter for 11 KV

Need PF (power factor) meter for 11 KV

(OP)
Can someone please recommend a PF meter that will work on 11 KV delta feeders (about 6400 v per phase)?
Some of our generators are reading a low power factor (80-85%). But because the generators are switched around to feed different feeders, it would make sense to correct our PF at the feeders. So my goal is to measure PF at the feeders, peak and off peak, and then I can size a capacitor bank that can be manually switched in and out by day-part. This is a small system 25 MW, about 25 Caterpillar 3500 series generators. Currently our feeders only have CTs to measure their current, but no PF measurement. Thanks for your advice :)

RE: Need PF (power factor) meter for 11 KV

I'd kill two birds with one stone and update the feeder protection with something modern that can provide your metering as well as better feeder protection and more complete event information.

RE: Need PF (power factor) meter for 11 KV

Look for a PF meter that will accept PT and CT inputs.
But David's answer may be the more professional approach.
