AEMC 2136.5 Digital Transformer Ratiometer DTR® Model 8510

Designed for on-site power, potential, and current transformer testing, the AEMC DTR 8510 Motor & Transformer Tester accurately measures primary to secondary turns ratio when connected to a non-energized transformer, all while simultaneously displaying polarity and excitation current. Fully automatic using a ANSI IEEE compliant test method, the AEMC DTR 8510 requires no user calibration, range selection, hand cranking, or tedious balancing. At each measurement, the AEMC 8510 self-calibrates and checks for open windings, connections, circuit breakers, short circuits, incorrect test lead placement, and reverse polarity—automatically.

Key Features:

• Ratio Testing: PT-VT from 0.8000:1 to 8000:1 and CT from 0.8000 to 1000.0 (Auto-Ranging)
• Performs tests 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
• Included DataView software allows for instrument configuration, download of stored measurements, and test results printed in a report format
• Display warns of incorrect lead connection, reverse polarity, open, and short circuits
