WINRES-20 BLUE, 20A Winding Resistance Tester with Bluetooth & Printer

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

The smart design of the WINRES-20 BLUE makes easier to determine the end of measurement automatically according to users’ decision. WINRES-20 BLUE 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 0.1 μΩ resistances, WINRES-20 BLUE can measure up to 100,000 Ω resistances. WINRES-20 BLUE discharges the measured circuit after each test. For inductive load, WINRES-20 BLUE can demagnetise the load. The temperature measurement input enables one to connect an optional sensor to WINRES-20 BLUE and perform temperature correction automatically. WINRES-20 BLUE’s intelligent software allows controlling the current flow if there is a failure in the current circuit. With this feature, WINRES-20 BLUE procures added safety to users.

A 7-inch TFT touch display allows WINRES-20 BLUE to show all measurement results on a single screen. WINRES-20 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.

With the HighTest Data Management Platform (DMP Software), users can control WINRES-20 BLUE, 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-20. WINRES-20 BLUE 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 BLUE, 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-20 BLUE can control tap changer (raise and lower) with its tap changer outputs.

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