OPTICAL CURRENT, VOLTAGE SENSORS IN AN EHV SERIES CAPACITOR BANKS APPLICATION

摘要

The fault tests demonstrated the capability of the optical voltage and current sensors to measure highly non-linear signals. While the use of a voltage transformer does not appear to significantly increase the accuracy of the MOV energy calculations in this case, it is anticipated that future series capacitor bank applications will adopt the optical CT technology due to its excellent performance, ease of installation, higher reliability and lower maintenance cost (no electronics on the platform).
