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.

a)In a 3-phase 4-wire circuit, a circuit breaker is selected to protect the circuit whose highest fault level is 6.6 MVA. Determine the required minimum breaking capacity in kA. (Note: Covert 3-phase power in terms of kA to find answer.) b)Using the below, determine the required minimum making capacity in kA as a “peak value”. Rate breaking capacity (Icn) ka: Icn<= 1.5 Factor = 1.41 1.5
