Abstract

The universal device for anti-biphasic protection of triphase electromotors consists of three voltage transducers. Each transducer has a magnetic core inside an insulated cage that lodges a current winding comprising one spire in series with the phases, which powers the electromotor, and a voltage winding, which powers intermediate relays whose NO contacts are in series with the self-control diagram of a contactor which controls the triphase electromotor feeding.
