TURA-01 BLUE Brochure EN

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


  • Turns ratio measurement (Single-phase and three-phase measurement)
  • Ranges from 0.8 to 33,000 ratio measurement
  • High Accuracy (0.08 %)
  • 1V, 4V, 10V, 40 V and 100 V AC test voltage
  • Ratio Error measurement
  • Excitation Current, Phase Angle, Polarity measurement
  • Built-in Bluetooth control and communication
  • Built-in printer
  • Internal memory, USB Flash Drive
  • PC control via USB cable
  • 4.3-inch large colour touch display
  • Optional expansion feature with Three-Phase Adapter (TPA-03).


Besides the ratio measurement, TURA-01 BLUE can also measure excitation current, phase angle, polarity and ratio error.

Even though it 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 depends on transformer configuration. Therefore, the operator doesn’t need to search for the connection diagram. It has a wide operations range from high excitation
current transformer to high powered power transformer at substation with the 1 V, 4 V, 10 V, 40 V and 100 V AC test voltage generation capability.

4.3-inch colour touch screen 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 Record). With the HighTest Data Management Platform (DMP Software), the user can control TURA-01 BLUE and analyse measurement results. Operators can easily print the measurement results with 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 staffs. By using the optional TPA-03 three-phase Adapter, user can make 3 phase connection and can test all phases simultaneously. TURA-01 BLUE is a light, compact and rugged device with the protection of IP67 (case closed).
