Digital Transformer Turns Ratiometer Model 8510
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.
FEATURES
• 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 (90/240) V supply, (50/60) Hz via external
smart/fast battery charger; completely charge in less than
4 hours
• Two internal NiMH batteries provide up to 10 hours of
continuous operation
• Tests performed by exciting the primary and reading
the secondary – provides 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
• Stores up to 10,000 test results in internal memory
• USB port facilitates configuring the instrument and
downloading test results
• Includes DataView®
analysis software for programming,
downloading, storing and report generation of test data.
