It is the ratio of voltage across the whole string to the
product of number of discs and the voltage across the
nearest disc to the conductor.

Multimeter show phase to neutral volt 230 the per phase but phase to phase 415 not show 460 why.

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
