The DTR® (Digital Transformer Turns Ratiometer) 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.

Features

• Measures power transformers, VT/PTs and current transformer CT turns ratios
• Displays turns ratio, excitation current, winding polarity, and % deviation from the nameplate values
• Smart/fast battery charger with universal input voltage (100-240V, 50-60Hz) charges batteries in less than 4 hours
• Ratio test results in less than 7 seconds
• Internal NiMH battery packs provide up to 10 hours of continuous operation
• Tests performed by exciting the primary and reading the secondary; provide safer conditions for the operator
• 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 ensures clearer visibility in any lighting environment day or night
• Low battery indicator
• Includes 15-foot lead set
• Stores up to 10,000 test results in internal memory automatically or by user selection
• Filter selection to improve test results in electrically noisy environments
• USB port facilitates configuring the instrument and downloading test results
• Includes DataView® software for instrument configuration, data storage, analysis, and report generation

Applications

• Power transformers
• Potential transformers
• Current transformers
