Winding Resistance tester

WINRES-20 is designed using advanced engineering technology to measure the winding resistance of transformers. WINRES-20 can measure current, voltage, power transformer windings and shunt resistors. Applying up to 20A Direct Current allows WINRES-20 to measure the resistance of the transformers fast and accurate. The smart design of the WINRES-20 makes easier to determine the end of measurement automatically according to users’ decision.

WINRES-20 can measure two resistance values simultaneously with its two voltage measurement channels. Users can prefer to test two primary or two secondary or one primary and one secondary winding according to the configuration of transformers. Beginning from 0.01 μΩ resistances, WINRES-20 can measure up to 100,000 Ω resistances. WINRES-20 discharges the measured circuit after each test. For inductive load, WINRES-20 can demagnetise the load. The temperature measurement input enables one to connect an optional sensor to WINRES-20 and perform temperature correction automatically.

Three-Phase Adaptor TPA-03 (optional accessory) allows connecting all primary and secondary sides concurrently, whereby users can select either to test the resistance of all phases or selective phases. With the TPA-03 option, WINRES-20 can control tap changer (raise and lower) with its tap changer outputs.

WINRES-20 is a light, compact and rugged device with the protection class IP67 (case closed).

Winres - 20B BLUE contains all the features of the other models scuh as battery, bluetooth and printer.    

A 7-inch TFT touch display allows WINRES-20B BLUE to show all measurement results on a single screen. WINRES-20B BLUE can be controlled by USB and built-in Bluetooth interface and users can record/store measurement results. In case setting up Laptop or PC for the field test is difficult; users can record data to the device’s internal memory (up to 100 Test Records) or to an external USB flash memory.
