A Metal-Oxide Surge Arrester model with active V-I characteristics
Generally a model of Metal Oxide Surge Arrester (MOSA) for numerical analysis uses a nonlinear resistance. But actual Voltage-Current (V-I) characteristics of MOSA have a hysteresis loop in the time domain like the i-Φ characteristic of a transformer and frequency dependency.
