8510

8510 is an easy-to-use portable digital transformer turns ratiometer. It is 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.

• Measures power transformers, VT/PTs and current transformer CT turns ratios
• Displays turn ratio, excitation current, winding polarity and % deviation from the nameplate values
• Universal voltage (90-240V supply, 50-60Hz) via external smart/fast battery charger
• Internal NiMH battery packs provide up to 10 hours of continuous operation
• Tests performed by exciting the primary and reading the secondary
• Display warns of incorrect lead connection, reverse polarity, open and short circuits
• Easy connection and test setup; no calibration or balancing required
• Large dual display with adjustable contrast
• Low battery indicator
• Stores up to 10,000 test results in internal memory
