Transformer Turns Ratio Tester (TTR) is a precision instrument designed to accurately measure the turns ratio of power, distribution, and instrument transformers. It is an essential tool for verifying transformer performance, detecting winding faults, and ensuring compliance with industry standards during manufacturing, installation, and maintenance.
This device works by applying a low-voltage AC signal to one winding of the transformer and measuring the induced voltage in the corresponding winding. By comparing these values
Built for reliability and ease of use, the TTR tester typically features a user-friendly interface, digital display, and automated measurement functions. It supports single-phase and three-phase transformer testing, including testing of tap changers without the need for complex manual calculations.
