The Chauvin Arnoux DTR 8510 is a portable digital transformer ratiometer designed for on-site testing of power, potential and current transformers. When connected to a non-energised transformer, the DTR accurately measures the primary-to-secondary turns ratio, while simultaneously displaying the polarity and excitation current.
At each measurement, the DTR automatically checks for open windings, connections, circuit-breakers, short circuits (excess excitation current), incorrect test lead placement, and reverse polarity. Tests are performed at low voltage and, unlike on other ratiometers, step-down excitation is employed. This method, in conjunction with an integral H/X reverse protection circuit, guards against the generation of hazardous test voltages.
Up to 10,000 tests can be stored in the DTR 8510’s internal memory. A large, dual line alphanumeric LCD with adjustable contrast and backlighting guarantees fast, accurate display and day/night readability. Both rugged and reliable, the DTR 8510 is equipped with an attractive, sealed structural polypropylene case designed to withstand the rigours of field use.
