Megger Portable TTR Test Set

Megger Portable TTR Test Set

The Megger TTR20 is an automatic handheld 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.
The unique design of this instrument is well suited for use in a variety of harsh environmetns and is particulary suited for testing in substations, transformer-manufacturing environments and meter shops.
