Megger TTR20-1 - Handheld TTR - Transformer Turns Ratio Tester
The Megger TTR20 is an automatic hand-held battery operated transformer turns ratio tester. It is used to measure the turns ratio, excitation current and polarity of windings in single-phase and three-phase distribution and power transformers (tested phase by phase), potential and current transformers, and tapped transformers.
The unique design of the TTR20 allows the user to operate the tester while holding it in one hand. It effectively eliminates the user from having to kneel or bend down to operate the instrument and speeds up testing time. And realizing the extreme environments in which the TTR20 must operate, special attention has been paid to making it extra rugged with a high impact, shock resistant case, yet incredibly lightweight at a mere 870g (1.9 lbs). This design makes the instrument well suited for use in a variety of harsh environments, including substations, transformer manufacturing environments, and meter shops.
The TTR20 is designed for simple, one button operation with the measured results displayed on the easy-to-read LCD screen or can be printed to the optional printer. It features a high-contrast, backlit LCD screen which can be seen in bright or ambient light and comes ready to use right out of the box with no additional software needed.
