Functions, features:
It is used to test internal defects caused by the poor contact between the non-linear resistors of zero clearance metal arrester which is used by 10KV or under 10KV power system (replace the partial discharge detector within limits). It combines high-voltage DC power system, measurement system and control system together while it is of small size and light weight; it is very practical and can complete measurement of all the subjects at a time.
