Chauvin Arnoux DTR 8510 Digital Transformer Ratiometer
Power, potential, and current transformers can be tested on-site using the portable digital transformer ratiometer known as the DTR® 8510. The DTR® correctly measures the primary-to-secondary turns ratio while concurrently displaying the polarity and excitation current when attached to a non-energized transformer.
The Chauvin Arnoux DTR 8510 reliably measures the primary-to-secondary transformation ratio while also indicating the polarity and excitation current when linked to an uncoupled transformer.
The Chauvin-Arnoux DTR 8510 uses a test procedure that complies with the ANSI/IEEE standard and is entirely automated. Users are not required to carry out any balance or calibration.
