DC Resistance Tester (WIFI efficient version)

DC Resistance Tester (WIFI efficient version)

Type: ZC-205CW
ZC-205CW DC resistance tester is optimized designed to test  three-phase winding DC resistance of large-capacity transformer, is the latest generation of transformer DC resistance tester. ZC-205CW can test the three-phase winding DC resistance of the transformer at the same time, adjust the tap-changer directly, no discharging is required for the on-load tap-changing transformer. The test speed is much faster than the similar products in the market. And it can complete the test in 5~8 seconds. It also has the functions of unlimited code scanning and automatic data uploading. The server side can analyze and manage the data centrally, and export the data file in Excel format, which greatly improves the detection efficiency and saves labor and time.
