The TURA-01 100V Turns Ratio Tester is a specialized tool designed for precise measurement of the turns ratio in single-phase and three-phase transformers. It is particularly suited for use in various transformer configurations, thanks to its user-friendly interface and accompanying connection diagrams. The device offers exceptional measurement accuracy with a variance of just 0.08%, and accommodates a wide range of test voltages from 1V to 100V AC. Its versatility extends to measuring core excitation current, phase angle, polarity, and ratio error. The TURA-01 is also equipped to handle connections for three-phase transformer tests despite its single-phase cable setup. It features a 4.3-inch color touch screen that clearly displays parameters and results, and is rugged with an IP67 protection rating when closed. Additionally, its built-in rechargeable Li-Ion battery and thermal printer make it ideal for field applications, providing immediate printed results and supporting data storage for up to 100 tests via USB, Bluetooth, and flash memory. HighTest Data Management Platform allows for further control and analysis on a PC.

The TURA-03 Series is engineered to measure the turns ratio of both single-phase and three-phase transformers with precision and efficiency. The device supports a wide ratio measurement range with an accuracy of 0.08% and is capable of assessing core excitation current, phase angle, polarity, and magnetic balance. It automatically detects vector groups, simplifying connections without the need for a manual. Designed to operate on high excitation current transformers and high voltage power transformers in substations, it provides selectable test voltages from 1V to 250V AC. Its 7-inch TFT touch display ensures all measurements are visible on one screen, while its USB and optional Bluetooth functionalities allow for seamless data management. Embedded with a printer, users can generate immediate hard copies of results. The device is protected with an IP67 rating and can also control tap changers. It's a compact, rugged testing solution beneficial for a wide range of transformer testing applications.

The TRIORES-20 Series is specifically engineered to measure the winding resistance of both three-phase and single-phase transformers. It operates with up to 20A Direct Current, ensuring precise and rapid resistance measurements. This advanced system can measure resistances as low as 0.1 μΩ and as high as 100,000 Ω. The embedded intelligent design allows users to automate the end of measurements and supports both dynamic resistance control of on-load tap changers and demagnetization of inductive loads. Enhanced with temperature measurement input, it auto-corrects measurements considering temperature variations. The system integrates a 7-inch TFT touch display for real-time monitoring, and supports USB and optional Bluetooth interfaces for data management. Additionally, measurements can be stored directly on the device, on external USB drives, or managed through the HighTest Data Management Platform on a PC. The system features a built-in printer, optional battery for testing without power availability, and a user-friendly interface that includes multi-language support.
