TURA-03 SERIES Brochure EN

TURA-03 BLUE is designed using advanced engineering technology to measure the turns ratio of single-phase and three-phase transformers. TURA-03 BLUE has a fast, easy and accurate TTR measurement features for current, voltage and power transformers using its user-friendly software. By using ANSI/IEEE C57.12.90 measurement method TURA-03 BLUE can produce precise results. TURA-03 BLUE is one of the most accurate devices with its wide range (0.8 to 50,000) ratio measurement capability and high precision (0.08 %).

Besides the ratio measurement, TURA-03 BLUE can also measure excitation current, phase angle, polarity, and ratio error. Even though TURA-03 BLUE has three-phase cable configuration, users can also make single-phase transformer tests. TURA-03 BLUE can detect vector groups automatically. TURA-03 BLUE has a wide operation range from high excitation value current transformer to high powered power transformer at substations with the 1V, 4V, 10V, 40V, 100V and 250V AC test voltage generation capability.

A 7-inch colour touch display allows TURA-03 BLUE to show all measurement results on a single screen. USB, Built-in Bluetooth and Flash Memory features allow TURA-03 BLUE to control, record and store measurement results (up to 100 Test Records). With the HighTest Data Management Platform (DMP Software), users can control TURA-03 BLUE and analyse measurement results. Operators can easily print the measurement results with the 2.28-inch built-in Printer of TURA-03 BLUE. Multi-language capability and user-friendly operation menu make it easy to control TURA-03 BLUE, even by less trained staffs.

TURA-03 BLUE can control tap changer (raise and lower) via its tap changer outputs. TURA-03 BLUE is a light, compact and rugged device with the protection of IP67 (case closed).

In addition to ratio tests, TURA-03 BLUE can be used to perform Magnetic Balance Test as well.
