Turns Ratio Meters

 

Transformer turns ratio can help to detect 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 portable units from HAEFELY are ideal for acceptance testing and on-site maintenance testing of transformers according to IEEE, IEC, and ANSI standards.


Transformer Turns Ratio Models:

Excitation voltage up to 100 V:     TTR 2795

Excitation voltage up to 250 V:     TTR 2796
