The Megger TTR20-1 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 three-phase distribution and power transformers (tested phase by phase), potential and current transformers, and tapped transformers.
