AEMC®'s portable digital transformer ratiometers (DTR®) are designed with safety in mind for on-site testing of power transformers, VT/PTs, and current transformers CT turn ratios with easy setup. No calibration or balancing required.
When connected to a non-energized transformer, AEMC Transformer Turns Ratiometers accurately measure primary to secondary turns ratio, while simultaneously displaying polarity, excitation current and % nameplate deviation.
No user calibration, range selection, hand cranking, or tedious balancing is required.
At each measurement, our transformer ratiometers automatically self-calibrate and check for open windings/connections/circuit breakers, short circuits (excess excitation current), incorrect test lead placement, and reverse polarity.

Primary to secondary turns ratio, Polarity, Excitation current, Automatic self-calibration
Digital transformer turns ratiometer for on-site testing of power, potential, and current transformers. Measures primary to secondary turns ratio, polarity, and excitation current. Automatically self-calibrates and checks for open windings/connections/circuit breakers, short circuits (excess excitation current), incorrect test lead placement, and reverse polarity.
Quick integrity tests on transformers/capacitors, Audible and visible indication
Hand-held instrument for performing quick, basic integrity tests on transformers and capacitors. Verifies transformer winding continuity without requiring full transformer ratio test. Simple, single-button operation with built-in fuse protection.
