An LED readout provides an instant display of the number of turns when testing toroidal transformers or the turns ratio when testing E/I laminated transformers. Transformers up to 15 lbs can be placed ...

The Megger TTR25 is an automatic hand-held battery operated transformer turns ratio test set. It is used to measure the turns ratio, excitation current and polarity of windings in single- and ...

Weighing just 3.3 lbs., the Megger TTR100 handheld test set measures the turns ratio, excitation current, phase displacement, DC resistance, and polarity of windings in single-phase and three-phase ...

With the new MCT1605 test set from Megger, comprehensive testing of current transformers – including multi-ratio types – can be carried out quickly and easily.

A close collaboration with major transformer manufacturers has lead to the new Tettex 2796 Transformer Turns Ratio Meter. It combines mobility and user friendly handling with unmatched accuracy of ...

Finally, winding resistance tests are invaluable when fault finding transformers, as many transformer faults or problems will cause a change in the DC resistance measured from the bushings.
