TTRU1 - ADV

TTRU1 - ADV is a handheld transformer turns ratiometer. Power through transformer electromechanical tests with the new TTRU1, the latest handheld transformer turns ratiometer from Megger. Perform routine polarity validation and turn ratio tests on power, distribution, and instrument transformers guided by color-coded leads, clamps, and customizable on-screen vectors that match the transformer nameplate under test. In addition to turns ratio tests, it adds go/no-go short circuits, open circuits, and inductance test capabilities. The easy-to-follow setup ensures the right result the first time - just click start and perform over 1000 turn ratio tests on a single NiMH AA battery charge! When it’s time to recharge the batteries, connect to any standard USB wall charger or connect to your PC. It is designed to test distribution, instruments (CTs and PT/VTs), and power transformers. With minimal input from the user, it delivers the required AC voltage and current to obtain accurate results.
