• The DTR 8510 is totally 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.
• The measurements are displayed quickly and accurately

Functions – 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 polarityn 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 analyse the measurements and generate test reports.
