Answer / s.ramesh babu

PT Name Plate details is 11kv/110/root3.
But Your EM name plate details is 415/110/root3.
and CT ratio is 30/5A.

Step:-1
Calculate voltage is 11000/415=26.50
Step:-2
Calculate CT is 50/5=10A.
Step:-3

Now EM multification factor is 26.50*10=265.06.

Answer / k.prakashchandra

Meter constant is 100x6 =600 if ct and pt ratios are not
incorporated (see name plate).160 imp/Kwh is not the meter
constant and it is like rev/Kwh in EM meters
