RVUNL EE POWER SYSTEM QUIZ 4

If Z₁, Z₂, Z₀ are positive, negative and zero sequence impedances of a fully transposed transmission line, then

The zero-sequence current of a generator for line to ground fault is j4 pu. Then the current through the neutral during the fault is

When the sinusoidal steady state current is called the symmetrical short circuit current, then the unidirectional transient component is called

Series reactors are used to

An alternate has 20%, 25% and 5% positive, negative and zero sequence reactance’s. What is the value of neutral grounding reactance so that the fault current for single line to ground fault is equal to rated line current?
