TURA-03 SERIES 250V 3∅ TURNS RATIO TESTER
TURA-03 is designed to accurately measure the turns ratio of single-phase and three-phase transformers. TURA-03 performs fast and accurate turns ratio measurements on current, potential and power transformers via its user-friendly interface.
With market-leading accuracy, the TURA-03 has a very wide ratio measurement capability with a precision of 0.08 %. TURA-03 is able to measure the core excitation current, phase angle, polarity, ratio error and magnetic balance. TURA-03 can detect vector groups automatically. The instrument also contains a helpful list of connection diagrams for the various transformer configurations. The operator simply selects the one they need to be displayed. Therefore, there is no need for an additional manual or diagrams to understand the cable connections for each vector groups. Selecting the right vector group is enough and device shows how to connect the cables to the transformer.
The instrument has a wide operating range for use on equipment such as high excitation value current transformers and high voltage power transformers in substations. The instrument can generate 1V, 4V, 10V, 40V, 100V and 250V AC test voltages.
A 7-inch TFT touch display allows TURA-03 to show all measurement results on a single screen. USB, Bluetooth (Option), and Flash Memory features allow TURA-03 to control, record and store measurement results, (up to 100 Test Records). Using the HighTest Data Management Platform or a.k.a. (DMP Software), users can control TURA-03 and analyse measured results and records. If an immediate hard copy of the results is required the TURA-03 also allows for this via an embedded 2.28-inch printer.
Multi-language capability and user-friendly menus make it easy to control the TURA-03 instrument, even by less trained staff. TURA-03 can also control the tap changer, (i.e. raise and lower) via its tap changer outputs. TURA-03 is a light, compact and rugged device with an IP protection class of IP67, (case closed). In addition to ratio tests, TURA-03 can also be used to perform Magnetic Balance Test.
DEVICE HIGHLIGHTS
Single-phase & three-phase ratio measurement
With TURA-03’s three-phase cable configuration, users can measure turns ratio of both three-phase and single-phase transformers.
7-inch TFT Colour Touch Screen
TURA-03 is built-in with a 7-inch TFT Colour Touch Screen which is visible under both bright sunlight and dim lit environment.
Optional Rechargeable Li-Ion Smart Battery
TURA-03 comes with a 14.4V Li-Ion smart battery which enables you to make tests while on field. TURA-03 works on both main power and consuming battery power.
