Handheld Transformer Turns Ratiometer (37.5V Max Induced Voltage)

Power through transformer electromechanical tests with the new TTRU1, the latest handheld transformer turns ratiometer from Megger. Perform routine polarity validation and turns ratio tests on power, distribution, and instrument transformers guided by colour-coded leads, clamps, and customisable on-screen vectors that match the transformer nameplate under test. In addition to turns ratio tests, the TTRU1 adds go/no-go short circuit, open circuit, and inductance test capabilities. The easy to follow setup ensures the right result the first time – just click start and perform over 1000 turns 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.

DETAILED DESCRIPTION
The TTRU1 is designed to test distribution, instrument (CTs and PT/VTs), and power transformers. With minimal input from the user, the TTRU1 delivers the required AC voltage and current to obtain accurate results.
Reduce training time with the intuitive full colour Hi-bright LCD user interface of the TTRU1. The configurable
vector list in the TTRU1-ADV model saves information for transformers routinely tested, simplifying selection
of common transformer configurations and results interpretation. When exported, results are grouped by file
name, producing an XLSX/PDF report that is easy to read, email, or import into PowerDB. If you need results on the
spot, use the optional USB printer! Perform up to 1000 TTR tests on a single charge with AA NiMH batteries installed from the factory. When it is time to charge the batteries, connect the provided USB-C cable to any wall charger or computer USB port.
