Product Description

Product Description

ZZC-10A Built-in Battery Single Phase Transformer dc Winding Resistance Tester

This winding resistance tester is applied to the test for all kind of sensibility on-load DC resistance and low-voltage switcher touched resistance, cable or weld resistance of transformer, large generator, CTPT, etc. The instrument is characterized by fast test speed, high precision, intuitive display, strong anti-interference ability, small size, low power consumption, stable and reliable test data.

 

DC resistance measurement of transformer winding is an essential test project during transformer transfer, repair and changing tapping switch. Measuring DC resistance of transformer winding, you can check out weld or connection quality of down-lead, the winding inter-turn short circuit or open circuit, and whether tap-changer is well contacted. In the previous it is generally to use QJ44 double bridge to measure DC resistance, but the measuring current for this type of bridge is mA level current. So, measurement will take a long time, and accuracy is lower. In order to change the above situation, our company has developed ZZC-10A DC Resistance Rapid Tester.

This instrument is a high-precision regeneration product used to replace DC single/double bridge. Equipped with advanced switch power supply technology, the measurement speed of the instrument is faster a hundred times than that of the bridge. Using four and half bits LCD to display the measurement results and three and half bits LCD to display ambient temperature or test current value, it overcomes the shortcoming of other similar products that it is difficult to read value from the LED display in the sun and possesses automatic arc suppression function. The instrument is characterized by fast test speed, high precision, intuitive display, strong anti-interference ability, small size, low power consumption, stable and reliable test data. Built-in rechargeable battery pack (12V) and AC/DC dual-use, the instrument is very convenient for on-site and field test.

Transformer DC Resistance Tester adopts new power supply technology and has the characteristics of small size, light weight, large output current and can be automatically adjusted according to the load size. The whole machine is sampled by dual chips with higher accuracy. It can automatically complete self-test, data processing, display, printing and other functions, and has automatic discharge and discharge indication functions. The instrument has high testing accuracy and is easy to operate, and can quickly measure the direct resistance of the transformer.
