Traditional TCRs compensate reactive power from highvoltageside of transformer, so it demands highly of thyristor and its protection and measurement, thus the cost ofequipment is higher.
How to obtain working power supply from highvoltageside of active electronic current transformer (ect) is the key link impacting the reliability and accuracy of the instrument transformer.
