Answer Posted / madhu
Generally allThe CT operated meter is designed for a
capacity arround 5 A , the ct ratio 50/5, 100 / 5 means the
secondary current of the secondary winding will not exceed
more than 5A.Our kwh meter capacity max 5A so consumers more
requirement ex- 50A consumer load so our kwh meter not
measured the reading that cases using ct .ex 50/5 50a flows
in a line meter shows 5A its ratio 50/5 = 10 so ct ratio 10
ex our units 12/day multiply by 10 = 120 units/day
