The Three-Phase Megger TTR330 Test Set is fully automatic, self-checking, menu-driven unit. The test set measures the turn ratio, phase shift, and excitation current of power, distribution, and instrument transformers. A “-47” suffix added to the catalog number denotes a 230-V input power supply, rather than the standard 120-V supply. 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 TTR330 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. For three-phase measurements, the test set is connected to all three phases of the transformer to be tested. The TTR lead selection circuitry permits automatic measurement of all phases without changing connections.
