The AEMC DTR 8510 Digital Transformer is a portable digital ratio meter for testing power, voltage and current transformers.

When connected to an uncoupled transformer, the AEMC DTR 8510 Digital Transformer accurately measures the primary-to-secondary transformation ratio, while also indicating the polarity and excitation current.

The DTR 8510 is completely automatic and uses a test method which complies with the ANSI/IEEE standard. Users are not required to perform any calibration or balancing.

During each measurement, the DTR 8510 self-calibrates automatically and checks:

• Open circuits, windings, connections and cut-off circuits
• Short-circuits (excessive value of excitation current), Incorrect connection of the test cables
• Polarity reversals
• Measurements are displayed quickly and accurately

AEMC DTR 8510 Digital Transformer specifications:

• Transformation ratio: from 0.8000:1 to 8,000:1 (power and voltage transformers) and from 0.8000 to 1,000.0 (current transformers)  -Autorange function
• Testing by excitation of the primary and reading of the secondary, in order to guarantee user safety
• Display of alerts in the event of incorrect connection, reversed polarity in open circuits and short-circuits
• Digital display - display of the ratios, winding directions - % deviation in relation to the rated values and excitation current. The bargraph indicates the progression of self-calibration and measurement
• Storage of up to 10,000 measurement results in internal memory
• USB connection and DataView PC software supplied as standard to set up the instrument, download and analyze the measurements and generate test reports
• Power supply by NiMH rechargeable battery with external charger (battery life of 10 hours in continuous operation)
• IP53 protection
• IEC 61010 50V CAT IV safety
• Dimensions: 272 x 248 x 130 mm / 3.7 kg
