The paper describes capabilities of a topological model of three-phase, five-limb transformer to accurately represent its response when subjected to geomagnetically induced currents. The model is validated by close agreement of the predicted values a

Because traditional electric power distribution systems have been designed assuming the primary substation is the sole source of power and short-circuit capacity, DR interconnection results in operating situations that do not occur in a conventional

Transformer modeling for transient simulations has many challenges because of nonlinear and frequency-dependent behavior. Some of the model parameters are relatively easy to obtain from standard factory tests. Other parameters can only be obtained fr

The ability to predict or confirm ferroresonance depends primarily on the correctness of the transformer model used by the computer simulation. Ferroresonance is introduced and a general modeling approach is given. An overview of available literature

Core saturation instability is a condition resulting from excess low-order harmonic AC/DC system interactions, amplified by increasing transformer flux offset which, in turn, is driven by the interaction between the harmonics and the converter. A sma

Ferroresonant overvoltages have been recognized as a threat to arresters installed on underground distribution systems. Extensive tests have been performed to evaluate the thermal and electrical performance of MOV arresters exposed to this duty. Arre
