HZ-2102 Zinc Oxide Lightning Arrester Test Equipment

1 Lightning arrester test equipment Overview
HZ-2102 Lightning Arrester Test Equipment for detecting the zinc oxide arrester (MOA) of each phase electrical performance. The instrument is suitable for on-site live detection of zinc oxide surge arresters of various voltage levels and factory tests and acceptance tests performed by laboratories in the event of a power failure. By measuring the full current and resistive current and other parameters, you can find the zinc oxide arrester internal insulation damp and valve flaws and other dangerous defects aging.

2 Lightning arrester test equipment features and features
