This paper investigates the impact of load power factor on sympathetic inrush current. Sympathetic inrush current is caused by the voltage drop across the system resistance due to energizing current of the parallel adjacent transformer. It may cause the protection system to mal-trip and the transformer outage. The presented model is validated by simulation using DIgSILENT. The simulation results show that sympathetic inrush current’s magnitude depends on the load power factors. This dependency is illustrated and analyzed, which gives deeper insight into sympathetic inrush current and transformer protection.
