Product Details

The automatic handheld Megger® TTR™20-1 TTR test set helps verify proper operation of a transformer as indicated by its windings' electrical properties. It measures turns ratio, excitation current, and polarity of windings in 1- and 3-phase distribution and power transformers (phase by phase), potential and current transformers, and voltage regulators.
Built to stand up to harsh environments, the TTR20-1 transformer turns ratio tester has rugged metal connectors and a high-impact, shock-resistant case. The instrument is well-suited for use in substations, meter shops, and transformer manufacturing locations.
Testing is 1-handed and easy: 1-button operation with results displayed on the high-contrast backlit LCD, or use the RS-232 port to send to a printer (sold separately). No additional software is needed.
