PCB Rogowski coil designs and performances for novel protective relaying

This paper presents PCB Rogowski coil designs and characteristics for advanced protection, control, and metering systems with new multifunction relays and fiber optic communication, providing fast response times to faults and easily adjusting to load and/or power system configuration changes. Since the new Rogowski coils are very accurate, protection levels can be set to lower thresholds reducing stress on the protected equipment. In addition, control and metering systems operate more accurately.
