CURRENT-LIMITING DEVICE Russian patent published in 1998 - IPC

Abstract RU 2115206 C1

FIELD: electrical engineering; alarm control systems. SUBSTANCE: device has resistor installation connected to transformer neutral, resistor installation monitoring unit connected in series with resistor installation built up of first and second stages. First stage functions to close ground switch which shorts out resistor installation and monitoring unit under phase-failure conditions; second stage functions to open transformer circuit breaker in response to short circuit in supply mains. EFFECT: improved design. 3 dwg
