The DTR 8510 is a portable digital transformer ratiometer designed for on-site testing of power, potential and current transformers. When connected to a non-energized transformer, the DTR accurately measures primary to secondary turns ratio, while simultaneously displaying polarity and excitation current.

The DTR is fully automatic and uses the IEEE C57.12-90-2006 test method. No user calibration, range selection, hand cranking or tedious balancing is required. 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. Measurements are displayed quickly and accurately.

The DTR is designed with operator safety in mind. Tests are performed at low voltage and, unlike other ratiometers, step-down excitation is employed. This method, in conjunction with in integral H/X reverse protection circuit, guards against the generation of hazardous test voltages normally associated with other transformer ratio measurement instruments.

A Large, dual line alphanumeric LCD with adjustable contrast and backlight guarantees day/night readability. Power is supplied by integral NiMH battery. Batteries are charged by an external smart charger. Both rugged and reliable, the Model 8510 is built into an attractive, sealed structural polypropylene case designed to withstand the rigors of field use.

Up to 10,000 tests can be stored in the DTR’s internal memory and downloaded to a PC for analysis and report generation using the included DataView software.

Constructed using only the highest quality electrical and mechanical components, the DTR sets the standard in advanced design, engineering and workmanship, and it will provide the user with years of accurate and reliable measurements and hassle free test report printouts.
