DC resistance measurement of transformer winding is an essential test during transformer delivery, repair and changing tapping switch. Usually, it is a time consuming task to use traditional methods (bridge method and voltage step down method) to measure transformer winding and DC resistance of high-power inductive device. In order to change this situation: shorten measurement time and reduce the staff’s workflow, our company has developed ZDC Transformer DC Resistance Tester.
1. Large output current, wide measuring range, small size, light weight, simple operation;
2. Fast test speed, high measurement accuracy, good retest capacity, strong anti-interference capability;
3. With perfect function of protection circuit and discharge alarm, reduce the wrong operation, good reliability;
4. Adopting high speed micro-controller to automatically complete the judgment of steady flow, data acquisition and processing and display resistance;
5. Using 192 * 64 large-screen LCD display, outdoor display is clearly visible;
6. Built-in high-capacity a non-volatile memory, can store 500 sets of measurement data;
7. Built-in high-precision real-time clock function, date and time can be calibrated;
8. With high speed micro thermal printer: can print measurement and historical data.
