The Chauvin Arnoux DTR 8510 is a portable, digital turn ratio tester for testing power, voltage and current transformers.
After connection to the currentless transformer, the DTR 8510 shows with high accuracy the number of turns ratio between the primary and secondary circuit and at the same time the polarity of the turns and the excitation current used.
The tests with the DTR 8510 run completely automatically according to a test procedure that meets the IEEE standard. Previous calibrations or adjustments are not necessary.
During the measurement, the DTR 8510 carries out an automatic self-calibration and checks:
- Windings, connections and circuits
- Short circuits (excitation current too high)
- the connection of the measuring line
- the polarity
