7070A-UI AC Ratio Bridge
- Calibration of Voltage and Current Transformers from a Single Instrument
- Calibration of Instrument Transformers with Different Rated Ratios Using One Single Reference Standard
- Calibration of Voltage Transformers (VT) Up to 800 kV When Used with MI 2500 Series of HV Dividers and Standard Capacitors
- Calibration of Current Transformers (CT) Up to 10000 A When Used With MI 7020 and/or 7200 Series of Precision Current Transformers and/or Current Comparators
- Short Measurement Times with High Accuracy and Low Inherent Burdens
- Instrument Applications are Valid for Single-Phase Measurements. Three-Phase Transformers Measurements Performed by Testing Each Phase Separately
- Test Frequency from 15 to 100
