The DTR® Model 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® Model 8510 accurately measures primary to secondary turns ratio, while simultaneously displaying polarity and excitation current.
Make sure your instrument is calibrated and ready to use the minute you open the box by adding our expert calibration service. Why Calibrate? For a complete descriptions of Transcat Service Levels, click here.

Overview
Product Highlights
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.
Ratio Testing: PT/VT from 0.8000:1 to 8000:1 and CT from 0.8000 to 1000.0 (Auto-Ranging)
Tests performed by exciting the primary and reading the secondary; provides safer conditions for the operator on step-down transformers
Continuity test indicates open or loose (high resistance) terminal connections
DC test mode eliminates errors due to magnetic build up
Stores up to 10 primary/secondary nameplate voltages to use in comparing test results
Displays ratio, test current, winding polarity, and deviation from nameplate voltage or ratio
Stores up to 10,000 test results
DataView® software included which allows configuring the instrument, downloading stored measurements and printing of test results in a report format
Display warns of incorrect lead connection, reverse polarity, open and short circuits
