Product Description
AEMC DTR 8510 Digital Ratiometer Transformer Tester
The AEMC DTR 8510 Digital Transformer Ratiometer is Portable
The AEMC DTR 8510 Digital Transformer Ratiometer 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 AEMC DTR 8510 Digital Transformer Ratiometer accurately measures primary to secondary turns ratio, while simultaneously displaying polarity and excitation current. The AEMC DTR 8510 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.
AEMC DTR 8510 Digital Transformer Ratiometer, upon completion of a test cycle, displays:
- Turns Ratio: The ratio of the primary to secondary voltage at the Transformer terminals due to test excitation
- Excitation Current: The RMS excitation current in the H winding due to test excitation during negligible loading of the associated X winding
- Polarity: Indicates the polarity (phase) of X relative to H
- Deviation: Indicates the deviation from nameplate ratio in Percent (%)
Additionally, the AEMC DTR 8510 Digital Transformer Ratiometer will display:
- Incorrect Lead Connections
- H/X Reversal (accidental step-up miss-connection)
- Short (excess excitation current)
- Open Circuits
- Circuit Continuity
- Low Battery
The AEMC DTR 8510 allows the user to store the data in automatic or manual mode after each test eliminating the need to write down the test results. Each measurement record is date and time stamped providing complete test information.
The AEMC DTR 8510 Digital Transformer Ratiometer Features:
- 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
