greater than SLV and in metering its viceversa?

Answer / khaleel
the main protection core especially ps class and backup
cores have higher saturation point that metering
core.....becoz they hav to handle large fault current..that
occur in faults..so its knee point will be about 600v..

knee point voltage should higher than required Vkp by relay to avoid CT saturated when fault happen
