Object-oriented sequence-domain representation of transformers for network analysis.

Object-oriented sequence-domain representation of transformers for network analysis.

An object-oriented admittance matrix representation of transformers with any number of circuits is developed for direct use in modern network analysis programs. An analysis of manually adjusted and load-tap-changing taps shows that the effective impedance can vary by 2:1 over the full range of taps...
