It is the voltage at which supply source changes over to
another.In generator excitation ,intially the excitation is
with outside dc supply in flashes, as gen voltage rises to
70% ,the excitation changes over to gen output.

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
