HM5002S Transformer DC Winding Resistance Tester

Profile

Dc resistance measurement of winding is one of the routine tests for transformers. The main purpose is to check whether the connection between winding and lead wire is good or not, and whether the resistance between each phase winding is balanced, etc., in order to ensure the safe operation of transformers.

Features

This transformer DC resistance tester USES 32-bit ARM as the core of the processing control , with automatic completion of self-calibration, steady flow judgment, data processing, resistance value display and other functions, can measure the dc resistance of various types of transformers and CT/P. The instrument can work directly with internal batteries, which greatly facilitates the use of field workers.
