According to IEEE, “a system or a portion of a system can be said to be effectively grounded when for all points on the system or specified portion thereof, the ratio of zero sequence reactance to positive sequence reactance (X0 / X1) and the ratio of zero sequence resistance to positive sequence resistance (R0 / R1) should be __________.”
A 11 kV, 10 MVA alternator has \(X_d^{''} = 15\% ,\;X_d' = 25\% ,\;{X_d} = 80\%\). It is connected to a load through a 2-cycle circuit breaker and a transformer.
