The DTR 8510 Dogital Transformer Ratiometer is fully automatic and uses the IEEE C57.12-90™-2006 test method. The DTR 8510 is a portable digital transformer ratiometer designed for on-site testing of power, potential and current transformers.When connected to a non-energized transformer, the DTR 8510 accurately measures the primary-to-secondary turns ratio, while simultaneouslydisplaying the polarity and excitation current.

Automatic calibration and balancing
No adjustments required
Low-voltage test
Measures power transformers, VT/PTs and current transformer turns ratios
Displays turns ratio, excitation current, winding polarity and % deviation from the nameplate values
Large dual display with adjustable contrast ensures clearer visibility in any lighting environment, day or night
Up to 10,000 tests can be stored
USB port to simplify instrument configuration and downloading of test results
NiMH battery life of up to 10 hours
