Product Description

20 A Winding Resistance Tester with Built-in Bluetooth & Printer

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

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

The smart design of WINRES-20 BLUE makes more apparent to determine the conclusion of measurements automatically according to users’ decision. WINRES-20 BLUE 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 μΩ resistances, WINRES-20 BLUE can measure up to 100,000 Ω resistance. WINRES-20 BLUE discharges the measured circuit after each test. For inductive load WINRES-20

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

WINRES-20 BLUE 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 Software), users can control WINRES-20 BLUE and analyse measurement results. Operators can easily print the measurement results with the 2.28-inch built-in Printer of WINRES-20 BLUE. 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 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 BLUE can control tap changer (raise and lower) via its tap changer outputs.

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