WINRES-20, 20 A Winding Resistance Tester

WINRES-20 is designed by advanced engineering technology to measure the winding resistance of transformers.

WINRES-20 can measure current, voltage, power transformer winding and shunt resistors. Applying up to 20 A DC allows WINRES-20 to measure the winding resistance of transformers quick and precise.

The smart design of WINRES-20 makes more apparent to determine the conclusion of measurements automatically according to users? decision. WINRES-20 can measure two resistance values concurrently by 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 transformer configuration.

Beginning from 0.01 ?? resistances, WINRES-20 can measure up to 100,000 ? resistance. 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.

WINRES-20?s intelligent software allows controlling the current flow if there is a failure on the current circuit. With this feature, WINRES-20 procures added safety to users. A 7-inch colour touch display allows WINRES-20 to show all measurement results on a single screen.

WINRES-20 can be controlled by USB-Bluetooth interface and users can record/store measurement results. In case setting up Laptop or PC for the on-field test is difficult; users can record data to the device?s internal memory (up to 100 Test Records) or external USB flash memory.

With the HighTest Data Management Platform (DMP), users can control WINRES-20 and analyse measurement results. Operators can easily print the measurement results with the 2.28-inch built-in Printer of WINRES-20. WINRES-20 has an optional battery power feature which allows users to make tests even when there is no electricity.

Multi-language capability and user-friendly operation menu make it easy to control WINRES-20, even by less trained staff.

Three-Phase Adapter TPA-03 (Optional) 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) via its tap changer outputs.

WINRES-20 is a light, compact and rugged device with the protection of IP67.
