GIS Conductive Circuit Measurement SystemBy using wireless communication between the main measuring device and the auxiliary measuring device, it is easy to measure the resistance value of the conductive circuit of various large switchgear in single-phase or three-phase simultaneously. Especially for GIS equipment with a large interval between conductive circuits and extremely long conductive circuits, the three-phase conductive circuit resistance can be measured at once, avoiding segmented measurement of resistance values and causing measurement errors in the total resistance of the conductive circuit. The measurement is accurate, easy to operate, and saves time.
