Power Systems The power level of nuclear reactor can be increase by ( K = multiplication factor ) raising the value of K above 1, but later bringing it back to K = 1. lowering the value of K below 1 but later bringing it back to K = 1. raising the value of K above 1 and keeping it at raised value. lowering the value of K below and keeping at that lowered value. raising the value of K above 1, but later bringing it back to K = 1. lowering the value of K below 1 but later bringing it back to K = 1. raising the value of K above 1 and keeping it at raised value. lowering the value of K below and keeping at that lowered value.

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 = 5 kV and V2 = 6 kV V1 = 6 kV and V2 = 5 kV V1 = 3.46 kV and V2 = 2.89 kV V1 = 2.89 kV and V2 = 3.46 kV V1 = 5 kV and V2 = 6 kV V1 = 6 kV and V2 = 5 kV V1 = 3.46 kV and V2 = 2.89 kV V1 = 2.89 kV and V2 = 3.46 kV ANSWER DOWNLOAD EXAMIANS APP
