Fully Automatic 3 Phase 250 V Transformer Turns Ratio Meter
A close collaboration with major transformer manufacturers has lead to the new 2796 Fully Automated 3 Phase 250 V Transformer Turns Ratio Meter. The instrument combines mobility and user friendly handling with unmatched accuracy of up to 0.03%. The higher test voltage of 250 V, together with the high precision, assures authentic results especially on large power transformers. Advanced analysis features like trending allow the user to detect problems at an early stage.
