11 kv metering is done in my factory.Meter show PF 1.000
but kvarh lag&lead show 24&94 respectively & Avg.PF
is .956 .? is what i do for inproove my PF to 1.000

Answer Posted / vinit patil

Your Meter reads Power factor at load center. In your case
load center might be far away from your tariff meter. Since
your APFC meter shows PF 1.00 but at your tariff meter on
11 KV side p.f still lagging. This happens because of
transformer inductance. Add 10 % KVAR of transformer
capacity directly in ON position. Your problem will go out.
