An Improved Fast Distance Relay to Mitigate the Impacts of Rogowski Coil Transducer Transient
IEEE Transactions on Power Delivery, 2022The Rogowski coil transducer's integrator will amplify the transmission error, which may lead to mal-operation of the relay. In this paper, a novel method of line relay based on the differential output of Rogowski coil is proposed.

Machinable Rogowski coil, design, and calibration
IEEE Transactions on Instrumentation and Measurement, 1996Rogowski coils are special types of mutual inductors often used to measure high AC and transient currents. Traditional designs are reviewed. The significant sources of error associated with typical coil designs are examined. A "machinable Rogowski coil" is introduced and discussed. The reasoning behind critical design choices is discussed. The improved

Using Rogowski coils inside protective relays
2013 66th Annual Conference for Protective Relay Engineers, 2013Traditionally, microprocessor-based relays incorporate a secondary current transformer to convert the 5 A or 1 A input current to a lower level for input to an analog-to-digital (A/D) converter as part of the input processing. The limits of this input circuit are well known, and relay designers take them into account when determining operating ...

IEEE transactions on power electronics
This article quantitatively investigates the design considerations for a planar Rogowski coil. Within one printed circuit board (PCB), the Rogowski coil is placed between the overlapping dc-bus traces, the dc-link capacitor, and the half-bridge.
