Description

TTRU1 BASIC, ADV, PRO, EXP
Handheld transformer turns ratiometer

 Single phase source and measurement for single phase, three-phase, and instrument transformer testing:
• Turns ratio, excitation current, and polarity
Up to 250 V induced, ±0.05 % accuracy
Accuracy guaranteed from -20 °C to 50 °C
Easily manage data with custom transformer entry,
auto saving, USB export, and PowerDB import
AA battery operated
• NiMH USB-C rechargeable batteries included

DESCRIPTION
Power through transformer electromechanical tests with
the new TTRU1, the latest handheld transformer turns
ratiometer from Megger. In addition to routine polarity
validation and turns ratio tests for power, distribution,
and instrument transformers, the TTRU1 can measure
short circuit impedance (leakage reactance) with the same
one time connection. Guided by colour-coded leads,
clamps, and customisable on-screen vectors that match
the transformer nameplate under test, the easy to follow
setup ensures the right result the first time - just click start
and let the patent pending internal shorting and lead
compensation do the work! 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. When connected to
the PC, TTRU1-EXP results can be directly downloaded.
