A Simulation Model to Predict EM Radiated Interference with Control Equipment in Electric Power Distribution Substations during Switching Operations

In electric power MV/LV substations, circuit-breakers have to be taken into account as EMI sources during switching operations. This paper deals with a simulation numerical model to predict electromagnetic interference with control equipment and electronic circuitry. A simulation example by applying the proposed model is carried out in order to show the flexibility of the computational tool. Transient electric and magnetic fields during switching operations are computed.
