Transformer Turns Ratio (TTR) Testers

Prevent equipment failure before it happens with transformer turns ratio, or TTR, testing in power grids. This simple electrical test ensures a transformer has the correct number of turns by applying a known AC voltage to one winding and dividing the number by the induced voltage appearing in the other. Use TTR testers to detect shorted turns, open circuits, winding deformation, and more through routine maintenance or troubleshooting.

For reliable analysis, ATEC offers a variety of TTR testers for rent at affordable rates from leading manufacturers such as Megger, Tettex, and AEMC. Our testers are equipped to handle both single-phase and three-phase testing with high accuracy.
