Digital ratiometer for transformers
The DTR 8510 is a portable digital ratiometer for testing power, voltage and current transformers.
When connected to an uncoupled transformer, the DTR 8510 accurately measures the primary-to-secondary transformation ratio, while also indicating the polarity and excitation current.
The DTR 8510 is totally 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 circuits,
-
Short-circuits (excessive value of excitation current),
-
Incorrect connection of the test cables,
-
Polarity reversals.
-
The measurements are displayed quickly and accurately.
Functions - 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 function,
