Haefely TTR 2796 measures transformer turns ratio with the greatest accuracy across the widest ranges of ratios in the industry.

Measuring turns or voltage ratio can help in detecting faulty transformer windings and defective tap changer positions. The excitation current and phase angle between the primary and secondary windings also provides additional information regarding the winding condition.

The Haefely TTR is supplied with application software that guides the user through the measurements and generating test reports quickly and easily. The accuracy, easy to use and additional features makes the TTR ideal for acceptance testing and on-site maintenance testing according to IEEE, IEC, and ANSI standards.
