Description
The Haefely Tettex 2293 combines transformer winding-resistance and turns-ratio measurements in one automatic test instrument.
A single connection arrangement supports tests on power and distribution transformers, reducing lead changes between measurements. The analyzer also provides core demagnetization and transformer diagnostic functions through a touchscreen interface. Dynamic resistance and tap-changer applications depend on the specified test arrangement. Confirm leads, control accessories and enabled functions through the rental or sales quote.
