The VITAS 2772 is a fully digital voltage instrument transformer (VT) measuring bridge. It incorporates more than 70 years of knowledge in this field and state-of-the-art technologies to exceed industry requirements.
The VITAS 2772 measures ratio and phase errors according to the latest IEC and ANSI standards.
Test objects and nominal transformers with large ratio differences can be measured with full accuracy, reducing the number of reconnections during testing.
The VITAS 2772 specified accuracy is independent of excitation or environmental conditions (temperature or humidity) and guarantees highly accurate results.
