New Transformer Turns Ratio Measuring Instrument

Friday, Aug 27, 2010

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 up to 0.03%.

The higher test voltage of 250 V together with the high precision assures authentic results especially on large power transformers. Advanced analysis features like trending allow the user to detect problems in an early stage. The automatic winding connection identification feature aids to find the correct transformer configuration. With the optional arbitrary phase shift software also special transformers with irregular vector groups can be measured.

During production and in the field the TTR 2796 is a highly valued diagnostic instrument. Within half a minute after connecting the measurement cables to the terminals of the transformer, the voltage ratio, turns ratio, ratio deviation, excitation current and phase deviation are displayed.
