Product Description

DC Winding Resistance Tester 10A for transformer

Transformer DC resistance is a must-test item in transformer manufacturing for semi-finished products, finished products factory test, installation, overhaul, after changing the tap changer, handover test and preventive test of the power department. It can check the welding quality of the winding joints and whether the windings have short-circuited between turns, also whether the contact of each position of the voltage tap switch is good, whether the actual position of the tap changer matches the indicated position, and whether the lead wire is broken, whether there is stock breakage, etc.

GDZRC-10U DC Winding Resistance Measuring Device is designed to measure DC resistance of inductive devices, such as transformers and power inductors.


Features
 

1. Adopts two power supply modes: internal lithium battery and AC220V.
2. Wide resistance measurement range, high resolution, and multiple current gear options.
3. With automatic test (blind test) function.
4. With perfect back EMF protection function.
5. With temperature conversion function, which is automatically converted to the resistance value at the standard temperature.
6. The longitudinal test of the DC resistance of the on-load tap changer can be completed at one time.
7. High measurement accuracy, and has the characteristics of anti-interference, shock-proof, and easy to carry.
8. 5.0-inch 65K color touch screen, easy to operate.
9. Built-in large-capacity non-volatile memory, can store 500 sets of data.
10. Built-in high-speed micro thermal printer, which can print measurement data.
11. Built-in high-precision clock, real-time display time.
12. With U disk storage function.
