The TTR 2795 measures turns ratio with the highest accuracy in the industry and has one of the largest turns ratio ranges commercially available. This advanced instrument automatically recognizes winding connections and vector group numbers of transformer windings. Just connect the measuring cables and press the start button and get the test results.
The TTR 2795 provides a wide ratio range, which allows the user to determine the no load accuracy of CTs and PTs.
Features
- Fully automated measurement of turns ratio, voltage ratio, phase displacement and excitation current.
- Highest measurement accuracy in the industry of up to 0.03% makes the 2795 the perfect tool for preventive maintenance measurement.
- Build-in printer for quick test report generation and total prevention of data loss.
- User friendly self-explaining interface with one rotary push-button for easy access to the menu structure.
