WINRES-20

WINRES-20

• Resistance Measurement 0.01 μΩ - 100,000 Ω
• Current Output 0.001 A - 20 A DC
• High Accuracy 0.1 %

WINRES-20 are designed by 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 20 A Direct Current WINRES-20 to measure the resistance of the transformers fast and accurately.

The smart design of the WINRES-20 makes easier to determine the end of measurement automatically according to operators’ 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 resistance.

WINRES-20 discharge 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 intelligent software allows controlling the current flow if there is a failure in the current circuit. With this feature, WINRES-20 procure added safety to operators.

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

WINRES-20 can be controlled by USB and an optional Bluetooth interface and users can record/store measurement results.

In case setting up a 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 to an external USB flash memory.

With the Data Management Platform (DMP Software), users can control WINRES-20, 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 have an optional battery power feature that 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 experienced staff.

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 the tap changer (raise and lower) with its tap changer outputs.

WINRES-20 devices are light, compact and rugged with the protection class IP67 (case closed).
