The AEMC DTR 8510 High-Performance Ratiometer is a portable digital ratio meter for testing power, voltage and current transformers.
When connected to an uncoupled transformer, the AEMC DTR 8510 High-Performance Ratiometer accurately measures the primary-to-secondary transformation ratio, while also indicating the polarity and excitation current.
The DTR 8510 is competely automatic and uses a test method which complies with the ANSI/IEEE standard. Users are not required to perform any calibration or balancing.
During each measurement, the DTR 8510 self-calibrates automatically and checks:Open circuits, windings, connections and cut-off circuitsShort-circuits (excessive value of excitation current), Incorrect connection of the test cablesPolarity reversalsMeasurements are displayed quickly and accurately.
AEMC DTR 8510 High-Performance Ratiometer specifications:Transformation ratio: from 0.8000:1 to 8,000:1 (power and voltage transformers) and from 0.8000 to 1,000.0 (current transformers) -Autorange functionTesting by excitation of the primary and reading of the secondary, in order to guarantee user safetyDisplay of alerts in the event of incorrect connection, reversed polarity in open circuits and short-circuitsDigital display - display of the ratios, winding directions - % deviation in relation to the rated values and excitation current.
