The Megger TTRU3 ratio meter test set is a fully automatic, self-checking, menu-driven turns ratiometer. The test set measures the turns ratio, vector relationship, excitation current as well as transformer diagnostic health indicators of power, distribution, and instrument transformers. The design of this instrument is such that it operates properly, independent of line voltage quality and frequency. This allows use of any generator driven power source of 500W or higher.
The TTRU3 is designed to test ALL power, instrument, and distribution transformers without the need of traditional high voltage excitation. With our patent pending step up technique, you are no longer required to know the “proper” test voltage to apply to obtain a “good” result - the test set decides for you - all in a box that is up to 35% smaller and lighter than other turns ratio meters.
With 3Ø excitation, testing is up to five times faster than previous phase-by-phase switching single instruments, and errors due to loading of delta secondary and tertiaries are problems of the past.
The test set can be used to test single-phase and three-phase transformers, both with and without taps in accordance with the requirements of the IEEE C57.12.90 – 2013 and IEC 60076-1 standards. For three-phase measurements, the test set is connected to all three phases of the transformer to be tested. The TTRU3 applies all three phases simultaneously which permits automatic measurement of all phases without changing connections.
The TTRU3 is also designed to operate single phase on three phase transformers to help isolate transformer phase related issues. The TTRU3 measures turns ratio, phase deviation and excitation current readings which are displayed on the built in 7 inch color display or customer PC.
Unlike other transformer ratiometers, the TTRU3 operates in both step up and step down ratio mode. Step down ratio excites the primary and measures the induced voltage on the secondary, while step up excites the secondary and measures the induced voltage on the primary.
