A 3-phase generator rated at 110 MVA, 11 kV is connected through circuit breaker to a transformer. The generator having direct axis sub transient reactance 19%, transient reactance X’ = 26% and synchronous reactance 130%. The generator is operating at no load and rate voltage when 3 phase short circuit occurs between the breakers and the transformer. The magnitude of initial symmetrical RMS current in the breakers will be
