Why voltge arev transformed in to 132KV/66/KV/33KV like
that
Answer Posted / ankur
Vrms=Vpeak/sqrt(2)
Vavg=(2/pi)*Vpeak
Vpeak=(pi/2)*Vavg
so,
Vrms=(pi/(2*1.414))*Vavg
to get a average of 100Volt
the rms comes to be a multiple of 111V
so all voltages are multiple of 1.11
@Sonal: even 132 is 12*11

Explain about how is it working Earth fault'relay and wahts the resistance value of earth bed
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
