Three-phase transformer ratio meter TTRU3

Megger's NEW TTRU3 Three-Phase Transformer Ratio Meter uses a revolutionary technique that allows a range of measurements to be made on the transformer, including three-phase turn ratio change (patent pending).

Three-phase output voltage saves valuable time during testing. The advantages of the device include: • Checking and recognition of the phase shift of a group of connections by rotating the vector on the screen and automatic recognition of a group of connections • Accurate measurement of the phase shift (on phase-shift transformers and windings assembled in a "zigzag") • Fast measurements - simultaneous measurement of all three phases • Even more reliable - eliminates the need for internal switching, a common cause of equipment failure

TTRU3 is an important tool for determining the technical condition of transformers. It only takes one single instrument to carry out all measurements of the transformation ratio, to which only one three-phase set of connecting wires needs to be connected. The TTRU3 uses the latest 7" color touchscreen (180mm) display and optional printer to keep your test results at hand. Also, the device can be controlled remotely from your PC, and the measurement results can be saved to a USB flash drive.
