Answer / pravin kumar

The minimum Insulation Resistance value for the power cables
2mega-ohm/kv this is both applicable for LT& HT side
for ex:
11 kv power cable need IR value is 22 mega-ohm

Answer / pgr ram

for HT cables (6.6 KV to 33KV) above 500 megohms is
required. For LT cables (1100 volts) minimum 100 meg ohms
is required

Answer / ibrahim

(cable voltage rating/1000+1M ohm)x10

Answer / deepak marya
