Multiplying factor=connected CT ratio/meter CT ratio*connected PT ratio/meter pt ratio*scale factor
Scale factor=1(for kwh meter)
Scale factor=1000(for mwh meter)

Answer / 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

A 500 V shunt motor runs at its normal speed of 250rpm when the armature current is 200A. The resistance of the armature is 0.12 Ω. Calculate the speed when a resistance is inserted in the field reducing the shunt field to 80% of normal value and the armature current is 100A.
