how to calculate the multiplying factor for energy meter
with CT ratio given
Answer Posted / avinash pawar
MF = Main PT ratio × Main CT ratio / Meter PT ratio
Main PT ratio = 22kv / 110v
Main CT ratio = 400 / 5
Meter PT ratio = 11kv / 110v
So, MF = { 22000/110×400×5 } /11000/110
MF = 160

at work we have a 3 phase motor but on testing one phase isnt getting a reading. it runs 24 hours a day all week. stops and starts well no noise or heating. the phase isnt down to earth.is it just a bad meter reading or not? phases one and three came up with a resistance reading of 0.4 but phase 2 couldnt get anything shows up as open circuit.
