Description
The DTR® Model 8510 is an easy-to-use portable digital transformer turns ratiometer designed for on-site testing of power, potential and current transformers. When connected to a non-energized transformer, the DTR® Model 8510 accurately measures primary to secondary turns ratio, while simultaneously displaying polarity and excitation current.
The DTR® is fully automatic and uses an ANSI/IEEE compliant test method. No user calibration, range selection, hand cranking or tedious balancing is required. At each measurement, the DTR® automatically self-calibrates and 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.
DTR® Model 8510 – Cat. #2136.50 : Includes soft carrying case, NiMH batteries (installed), 115V power cord, set of (2) 15 ft leads, set of (2) alligator clips (red, black), 10 ft USB cable, external battery charger (90-264Vac, 50/60Hz) and USB drive with DataView® software and a user manual.
