Precision bridges for instrument transformer testing
As equipments for production instrument transformer testing, bridges described are particularly suitable; accuracy of ±0.1% for ratio and ±3 min for phase angle permits certification of transformers in highest accuracy class; direct readings of ratio correction factor and phase angle over range of 0.99 to 1.01 ±50 min eliminate need for calculations; safety and stability obtained.
