Title:
BRANCHING UNIT FOR BUS DUCT
Document Type and Number:
WIPO Patent Application WO/2018/158942
Kind Code:
A1
Abstract:
The present invention addresses the problem of a wiring system which is for a bus duct and is provided with current detectors for detecting ground faults in respective branched branching electrical circuits, wherein wiring becomes complicated when detecting ground faults by means of arithmetic processing. This branching unit for a bus duct is provided with: a cable that connects an input terminal connected to a conductor of the bus duct and an output terminal connected to a load; a current sensor that detects the value of the current flowing in the cable; and a measurement device that compares the detected value from the current sensor to a predetermined reference value and detects a ground fault, whereby ground faults can be detected in each branching unit for the bus duct.
