GOZ-ZDC-3A DC resistance quick tester
GOZ-ZDC-3A DC resistance quick tester is suitable for all types of power transformers, transformer windings and other inductive low-value resistor, however in the transformer transfer, overhaul, minor repairs, changing tap position, troubleshooting and pre-test conditions, it must measure the DC resistance of the transformer windings and charge current 3A. GOZ Technology can meet requirements like China State Grid Electricity Power Research Institute and other relevant authorities’ inspection, and issue a test report accordingly.
Also called: DC resistance tester, Transformer DC resistance tester, Transformer DC resistance meter, Inductive load DC resistance meter
1． DC resistance tester interface uses computer control with large screen backlit character LCD screen display, easy to operate.
2． Show a clear and friendly man-machine interface, the measurement process and instrument status prompt clear without excessive memory procedures for operator.
3． Linear compensation technology, test stable, high accuracy, fast speed, improving measurement efficiency, reducing the work intensity of the operator.
4． Technically using "four-terminal" measurement, eliminating measurement errors caused by lead resistance and contact.
5． Overvoltage protection function, can prevent the impact of counter electromotive force.
6． AC-DC dual-use, small size, light weight, easy to carry.
