Haefely Hipotronics 2795 Fully Automatic Three Phase Transformer Turns Ratio Meter
Haefely Hipotronics 2795 Fully Automatic Three Phase Transformer Turns Ratio Meter
On-site testing of turns ratio is an important basic measurement for power transformer diagnosis.
- Measures turns ratio, voltage ratio, phase displacement, and excitation current
- Selectable test voltages: 100V, 40V, 10V, and 1V
- Best accuracy in the industry at 0.03% for ratios 0.8-100
- Simplistic user interface for quick test setup
- Automatic winding connection identification and vector group detection for easy operation
- Color coded and labeled test leads for easy setup
- Remote control via laptop and application software
- Built-in printer for generating test reports
- Supplied in a compact and rugged case for portability
It helps to detect faulty transformer windings as well as defective tap changer positions. The simple ratio of turns or voltage and the related ratio error is not sufficient to detect all possible failures of a power transformer winding. The excitation current and the phase angle between primary and secondary windings give additional information about the winding condition. The TTR 2795 provides all these measurements in one compact instrument.
Transformer Turns Ratio Meter TTR 2795 is the next generation of the very successful Tettex transformer turns ratio meter line. The result of our close collaboration with worldwide TTR users and industry specialists in power and distribution transformers is this advanced instrument with its unbeaten performance. 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.
For an easy and fast detection of faulty tap positions, the measured turns ratios vs. tap changer position is displayed graphically.
