Fault current indicator e.g. short circuit indicator, for electrical switchgear in medium voltage region, has fault current acquisition device and fault current indicator device accommodated in equipment housing

摘要

The indicator (1) has an integrated voltage test system conforming to international electrotechnical commission (IEC) 61243-5 standards. A fault current acquisition device and a fault current indicator device are accommodated in an equipment housing (2). The equipment housing comprises voltage detector and voltage indicator (6) supplementary to the fault current acquisition device. The fault current indicator device, the voltage indicator and associated control elements (10) are arranged in a region of a surface of a front wall of the equipment housing.
