TTR Tester Repair

A transformer turns ratio (TTR) tester is a vital tool used to evaluate the turns ratio between the primary and secondary windings of transformers, ensuring proper transformer function and identifying issues like winding short circuits and insulation faults. TTR testers function by applying a low AC voltage to the primary winding and measuring the induced voltage in the secondary winding, which helps maintain the transformer’s efficiency and operational safety. Prominent brands in the industry include Megger, AEMC, and Vanguard Instruments. June Company provides expert repair, ISO-certified calibration, and stocks essential parts for TTR testers across various brands, supporting clients across the United States to keep their transformers in peak condition and compliant with industry standards.
