Megger TTR20-1 Transformer Turns Ratio Tester

The Megger TTR20-1 is a portable, battery-operated, automatic transformer turns ratio test set. Designed for handheld use, it measures the turns ratio, excitation current, and winding polarity in single- and three-phase distribution and power transformers (tested phase by phase), as well as potential, current, and tapped transformers.

The TTR20-1 features a unique design that allows users to operate the test set with just one hand, eliminating the need to kneel or bend down, thereby speeding up testing time. Understanding the harsh environments where the TTR20-1 is used, it has been crafted to be exceptionally rugged with a high-impact, shock-resistant case, yet it remains incredibly lightweight at only 870 grams (1.9 pounds).

Megger TTR20-1 Key Features

  • Simple, one-button operation
  • Lightweight, handheld
  • Battery powered (AA or LR-6)
  • Tests turns ratio, excitation current, and polarity
  • Ability to record via optional printer
