An overview,

The measurement of transformer DC resistance is a necessary item in the transformer factory inspection, handover test and preventive test of power equipment manufacturers and power generation and power supply departments. Development of the new company three loop dc resistance tester can realize three loop at the same time, three-phase automatic measurement, automatic three wire measurement, single phase measurement function, for YN, Y, and delta all kinds coupling transformer can realize automatic measurement, greatly improving the work efficiency, is the current domestic advanced dc resistance tester, resistance measuring instrument is ever updated products.
