The Megger TTR300 test set measures the turn ratio, phase shift, and excitation current of power, distribution, and instrument transformers. The test set is a portable instrument housed in a sturdy plastic case with removable lid and carrying strap. The inside lining of case is metal shielded.

The TTR300 test set can be used to test single-phase and three-phase transformers, both with and without taps in accordance with the requirements of the IEEE C57.12.90 – 1997 standards. Test results are saved to an external personal computer (PC) via an RS232 serial port.
