How to conduct a Hipot test on a 11KV cable?..

Answer / rajen thakkar

Hipot test is used to test the cable for Its more than
rated voltage level for which it is designed.so, for 11KV
cable 19KV DC is applied for 1 Minute to R&Y,Y&B,B&R lead
of cable one by one & armoring is connected to earth. 11KV
Cable should withstand this voltage.If cable insulation is
weak so it will breakdown at this higher votage
level.Before & After the Hipot test cable meggering should
be done By 5Kv Megger.
