if i conncet ct with ct ratio of 600/5 to an energy meter
having ct ratio of 100/5, the reading show by the meter
will correct, if wrong is there any method to calculate
correct value with shown value, if yes please state
it.....

Answer Posted / wareagle

If the meter is designed to use a 100/5 ct, it will receive
5 amps when the load is 100 amps. If the ct were a 600/5,
the meter would receive only 1/6 x 5 amps or 0.83 amps
which would be a low reading. You would need to multiply
the reading by 6 to get the correct value. You would likely
not get the the exact reading with the 600/5.
