Project Description

TURA-01 BLUE Brochure EN

TURA-01 BLUE is designed using advanced engineering technology to measure the turns ratio of single-phase and three-phase transformers. TURA-01 BLUE has fast, easy and accurate TTR measurement features for current, voltage and power transformers using its user-friendly software. TURA-01 BLUE is one of the most accurate devices with its wide range (0.8 to 33,000) ratio measurement capability and high precision (0.08 %).

Besides the ratio measurement, TURA-01 BLUE can also measure excitation current, phase angle, polarity, and ratio error. Even though TURA-01 BLUE has a single-phase cable configuration, the user can make three-phase transformer tests. TURA-01 BLUE can show all kinds of connection diagrams on display which can change depending on transformer configuration. The operator doesn’t need to search for a connection diagram. TURA-01 BLUE has a wide operation range from high excitation current transformer to high powered power transformer at substations with the 1V, 4V, 10V, 40 V and 100 V AC test voltage generation capability.

A 4.3-inch touch display allows TURA-01 BLUE to show all measurement results on a single screen. USB, built-in Bluetooth and Flash Memory features allow TURA-01 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-01 BLUE and analyse measurement results. Operators can easily print the measurement results with the 2.25-inch built-in Printer of TURA-01 BLUE. Multi-language capability and user-friendly operation menu make it easy to control TURA-01 BLUE, even by less trained staff.

By using the optional TPA-03 Three Phase Adapter, users can make 3-phase connections and can test all phases simultaneously.

TURA-01 BLUE is a light, compact and rugged device with the protection of IP67 (case closed).
