Problems with the turns ratio of any transformer can cause changes in the cores magnetic flux. This can cause it to heat up and totally fail. A TTR test set helps determine open circuits, short circuits and incorrect connections.
A TTR tester measures several electrical properties of the transformer and compares it with a database of baseline from the manufacturer. Any faults in the transformer will cause a deviation in the baseline data.
The Vanguard ART-01 TTR test set is a single phase tester powered with advanced microprocessor technology. This tester has a system that automatically recalibrates itself before conducting tests which ensures accurate results. It can measure turns ratios from 0.8 to 15000 or display it in percentage. It has a RS232 port that allows you to interface it with a computer and control it. You can view the test results in its back-lit LCD screen, making it convenient even on dim environments.
If you need to conduct tests on transformers but don’t have the right high voltage test equipment, consider renting it from Protec. We also offer other Vanguard test equipment to suit your needs. Give us a call and ask for a quote on test equipment rental.
