Winding dc resistance measurement is one of the routine test of transformer, which is to check the connection and mechanical properties between winding, winding and the lead,and whether the resistance between each phase winding is in balance to ensure the safe operation of transformer.
Transformer dc resistance tester with 32ARM kernel, which is the core of the process can control the whole machine, doing automatically self-calibration and steady flow judgment, data processing, display, and other functions, can manage all kinds of Dc resistance measurement of transformer and mutual inductor. greatly convenient the use of the field staff.
