Project Description

TURA-X Brochure EN

TURA-X is designed by advanced engineering technology to measure the turns ratio of single-phase and three-phase transformers. Turns ratio measurement of phase-shifting transformers can be done by using TURA-X. It has a fast, easy and accurate TTR measurement features for current, voltage and power transformers by its user-friendly software.

By using ANSI/IEEE C57.12.90 measurement method TURA-X can make precise results. TURA-X is one of the most accurate devices with its wide range ratio (0.8 to 50,000) measurement capability and high precision (0.08 %). Besides the ratio measurement, TURA-X can also measure excitation current, phase angle, polarity and ratio error. Even though TURA-X has three-phase cable configuration; the user can make single-phase transformer tests.

TURA-X can detect vector group automatically. TURA-X has a wide operations range from high excitation value current transformer to high powered power transformer at substation with the 1V, 4V, 10V,  40 V, 100 V, 250 V & 430 V AC test voltage generation capability. 7-inch colour touch display allows TURA-X to show all measurement results on a single screen. USB, Bluetooth (Option) and Flash Memory features allow TURA-X to control, record and store measurement results (up to 100 Test Record).

With the HighTest Data Management Platform (DMP), User can control TURA-X and analyse measurement results Operators can easily print the measurement results with the 2.28-inch built-in Printer of TURA-X. Multi-language capability and user-friendly operation menu make it easy to control TURA-X, even by less trained staff. TURA-X can control tap changer (raise and lower) via its tap changer outputs. TURA-X is a light, compact and rugged device with the protection of IP67 (case closed).

In addition to ratio tests, TURA-X can be used to perform Magnetic Balance Test as well.
