Abstract : The effectiveness of energy-diverter protection can be reduced by the presence of inductance between the energy diverter and the 'protected system'. Two primary effects caused by inductance have been noted. The first effect occurs when the fault-sensing circuit triggers the energy-diverter during a high-impedance fault. In this case a large voltage oscillation about the zero reference level appears at the 'protected system'. If the inductance is large, the oscillation will be maintained for a long period and will prevent quick removal of voltage. The second effect occurs when the faultsensing circuit triggers the energy diverter during a low-impedance arc. In this case the large inductance retards arc quenching. As the arc attempts to quench, the voltage oscillation reappears because of the energy stored in the inductor, and arc quenching is prevented. Observations on a system and an analysis of the circuit are discussed. (Author)
