Megger TTR25 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.
- Single and three-phase transformer testing
- Fully automatic; fast; easy-to-use; robust; lightweight
- Battery powered
- Tests turns ratio, excitation current, and polarity
- Simple, one-button operation
- Quick-start guide on front panel
- Operator-selectable languages
The unique design of the TTR25 allows the user to operate the test set while holding it in one hand.
The test set effectively eliminates the user from having to kneel or bend down to operate the instrument and speeds up testing time.
Realising the intense environments in which the TTR25 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 (1.9lbs).
The test set’s design makes this instrument well suited for use in a variety of harsh environments.
The TTR25 is particularly suited for testing in substations, transformer-manufacturing environments and meter shops.
It features a high-contrast, backlit LCD screen which can be seen in bright or ambient light.
