Digital Transformer Turns Ratiometers

Why Choose AEMC^®  Instruments Digital Transformer Turns Ratiometers?

Operator Safety

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.

• Injects into primary, read the secondary – Safer for the operator
• Stores your 10 most common transformer nameplate values – saves time and eliminates errors in testing
• Adjustable display contrast and backlighting - provides clear reading in all lighting conditions
• Polarized H and X input cable connectors – eliminates errors in set up
• Intelligent battery charging – prevents over charging, extends battery life

Quick and Accurate Measurements

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.

Easy to Operate - Automatic Measurements

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.

Key Features (DTR^® model 8510)

• Ratio test results in less than 7 seconds
• Smart/fast battery charger with universal input voltage (100-240V, 50-60Hz) charges batteries in less than 4 hours
• Display warns of incorrect lead connection, reverse polarity, open and short circuits
• Easy connection and test setup; no calibration or balancing required
