PARASITIC-GROUND CURRENT INDICATOR FOR ELECTRICAL SYSTEM

摘要

An electrical system contains two current-fed components having respective grounded housings. Each of these components is connected via a respective conductor to a common ground point. A signal-transmitting connection galvanically connects the housings two components to each other. A parasitic-current indicator is permanently installed in the system and detects parasitic currents (IS) flowing between the grounded housings and generates a warning at a predetermined signal level.
