Power Systems Consider a three phase, 50 Hz, 11 kV distribution system. Each of the conductors is suspended by an insulator string having two identical porcelain insulators. The self capacitance of the insulators is 5 times the shunt capacitance between the link and ground. Find the voltage across the two insulators V1 and V2? (V1 = Voltage of disc nearest to the conductor) V1 = 6 kV and V2 = 5 kV V1 = 2.89 kV and V2 = 3.46 kV V1 = 5 kV and V2 = 6 kV V1 = 3.46 kV and V2 = 2.89 kV V1 = 6 kV and V2 = 5 kV V1 = 2.89 kV and V2 = 3.46 kV V1 = 5 kV and V2 = 6 kV V1 = 3.46 kV and V2 = 2.89 kV ANSWER DOWNLOAD EXAMIANS APP
