AS PER THE PRACTICAL ASPECTS CONSIDERING PF
PRACTICALLY ....FOR 50 HP MOTOR WE HAVE TO TAKE 37.5 KW
(I.E. FOR 100 HP WE ARE TAKING 75 KW)......

Why in 6 KV XLPE cable termination kit used and why not in 380 V xlpe cable same is not used

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
