Description

Digital ratiometer for transformers

The DTR 8510 is a portable digital ratiometer for testing power, voltage and current transformers.

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

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.
  • 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
