TRIORES-20, 20A Fully Automatic Three-phase Winding Resistance Tester with Built-in Printer

TRIORES-20 Series is designed using advanced engineering technology to measure the winding resistance of transformers.
TRIORES-20 Series can measure current, voltage, power transformer windings and shunt resistors.
Applying up to 20A Direct Current allows TRIORES-20 Series to measure the resistance of the transformers fast and accurate.
The smart design of the TRIORES-20 Series makes it easier to determine the end of measurement automatically according to users’ decisions.
TRIORES-20’s measurement channels are designed in such a way that it can measure both three-phase and single-phase transformers’ winding resistance. Users need to connect the test cables just one time to measure all three phases while testing three-phase transformers.
Beginning from 0.1 μΩ resistances, TRIORES-20 Series can measure up to 100,000 Ω resistance. TRIORES-20 Series discharges the measured circuit after each test.
Dynamic resistance (OLTC) control of on-load tap changers, which can be performed simultaneously on all three phases, or a single phase.
For inductive load, TRIORES-20 Series can demagnetise the load. The temperature measurement input enables one to connect an optional sensor to TRIORES-20 Series and perform temperature correction automatically.

TRIORES-20 Series’s intelligent software allows controlling the current flow if there is a failure in the current circuit. With this feature, TRIORES-20 Series procures added safety to users.

A 7-inch TFT touch display allows TRIORES-20 Series to show all measurement results on a single screen. TRIORES-20 Series can be controlled by USB and optional Bluetooth interface and users can record/store measurement results. In case setting up a 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 TRIORES-20 Series, analyse and manage measurement results using a PC. Operators can easily print the measurement results with the 2.28-inch built-in Printer of the TRIORES-20 Series.

TRIORES-20 Series has 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 TRIORES-20 Series, even by less trained staff.

TRIORES-20 Series can control tap changer (raise and lower) with its tap changer outputs. TRIORES-20 Series is a light, compact and rugged device with the protection class IP67 (case closed).
