WINRES-20B, 20A Winding Resistance Tester with Battery & Printer

WINRES-20B is designed using advanced engineering technology to measure the winding resistance of transformers. WINRES-20B can measure current, voltage, power transformer windings and shunt resistors. Applying up to 20A Direct Current allows WINRES-20B to measure the resistance of the transformers fast and accurate.

The smart design of the WINRES-20B makes easier to determine the end of measurement automatically according to users’ decision. WINRES-20B 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-20B can measure up to 100,000 Ω resistances. WINRES-20B discharges the measured circuit after each test. For inductive load, WINRES-20B can demagnetise the load. The temperature measurement input enables one to connect an optional sensor to WINRES-20B and perform temperature correction automatically. WINRES-20B’s intelligent software allows controlling the current flow if there is a failure in the current circuit. With this feature, WINRES-20B procures added safety to users.

A 7-inch TFT touch display allows WINRES-20B to show all measurement results on a single screen. WINRES-20B can be controlled by USB and optional 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.

With the HighTest Data Management Platform (DMP Software), users can control WINRES-20B, analyse and manage measurement results using a PC. Operators can easily print the measurement results with the 2.28-inch built-in Printer of WINRES-20B. WINRES-20B has a built-in 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-20B, even by less trained staffs.

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-20B 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).
