Project Description

TURA-03B BLUE is designed by advanced engineering technology to measure the turns ratio of single and three-phase transformers. TURA-03B BLUE has a fast, easy and accurate TTR measurement features for current, voltage and power transformers by its user-friendly software. TURA-03B BLUE is a battery-powered device, which allows the user to take measurements even without power supply during on-field tests. 

By using ANSI/IEEE C57.12.90 measurement method TURA-03B BLUE can make precise results. TURA-03B BLUE 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-03B BLUE can also measure excitation current, phase angle, polarity and ratio error. Even though TURA-03B BLUE has a three-phase cable configuration; the user can make single-phase transformer tests as well.

TURA-03B BLUE can detect vector group automatically. TURA -03B BLUE 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 and 250 V AC test voltage generation capability. 7-inch colour touch display allows TURA-03B  BLUE to show all measurement results on a single screen. USB, Built-in Bluetooth and Flash Memory features allow TURA-03B BLUE to control, record and store measurement results (up to 100 Test Record).

With the HighTest Data Management Platform (DMP), User can control TURA-03B BLUE and analyse measurement results Operators can easily print the measurement results with the 2.28-inch built-in Printer of TURA-03B BLUE. Multi-language capability and user-friendly operation menu make it easy to control TURA-03B BLUE, even by less trained staff. TURA-03B BLUE can control tap changer (raise and lower) via its tap changer outputs. TURA-03B BLUE is a light, compact and rugged device with the protection of IP67 (case closed).

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