Weba gapped iron-core reactor experiencing less severe inrush compared with a transformer. Gapped iron-core reactors can be used as three single-phase units or three-phase units with a three- or five-legged core construction. The five core legs result in a zero-sequence impedance that is equal to the positive-sequence impedance. WebJun 8, 2024 · Zb = Base impedance (This is part of the per-unit system used to analyze power systems) A symmetrical synchronous generator operated at no load (i.e., with the main circuit breaker open), and rated 500 MVA, 22kV, is wye connected and solidly grounded. Generator constants: X d ’’= X 1 = X 2 = 15% ; X 0 = 5% 1.
