A Novel Transducer for Monitoring Surge Currents in AC Mains: Expectations and Reality

Abstract

The proliferation of surge-protective devices and switch-mode power supplies has radically changed the surge environment in low-voltage AC mains. Monitoring surge voltages has lost significance and can be misleading. Instead, surge currents should be monitored. The paper describes the performance of a silicon-based surge-protective device acting as a magnet for impinging surges in the presence of multiple metal-oxide varistors. This magnet is the first step toward the development of a transducer producing a voltage signal reflecting the surge current that can be delivered by the power system. That signal can then be applied to the voltage input of existing commercial power quality monitors.
