For a single line to ground fault the zero sequence current is given by j3 pu. The current carried by the neutral during the fault is

When a fault occurs in a power system the zero sequence component of current becomes zero. The type of fault is

The following sequence currents were recorded in a power system under a fault condition I_positive = j1.923 pu, I_negative = – j0.8 pu, I_zero = – j1.246 pu.The fault is

Which of the network gets affected by the method of neutral grounding?

Zero sequence current flows in a transmission line when there is

Zero sequence fault currents are absent when the fault is

When a line to ground fault occurs, the current in faulted phase is 100 A.  Zero sequence current in this case will be

Star connected, 3 phase, 11kV, 25 MVA alternator with its neutral grounded through 0.033 pu reactance has positive, negative and zero sequence reactance of 0.2 pu, 0.1 pu and 0.1 pu respectively. A single line to ground fault on one of its terminal would result in a fault MVA

The severity of line to ground and three phase fault at the terminal of an unloaded synchronous generator is to be the same. If terminal voltage is 1 pu and Z₁= Z₂=j0.1 pu, Z₀= j0.05 pu for the alternator, then the required inductive reactance for neutral grounding is

When a 50 MVA, 11 kV, 3-phase generator is subjected to a three phase fault, the fault current is -j5 pu. When it is subjected to a line to line fault, positive sequence current is -j4 pu. Positive sequence and negative sequence reactances are respectively
