What is a Rogowski Coil? Principle, design, Integrators
Rogowski coils in combination with protection relays, is used to sense/ detect faults in power systems and operate circuit breakers. Rogowski coils can be found within the circuit breakers for current sensing. They are used in frequency converters and inverters to sense the output currents of power electronic devices (IGBTs, MOSFETs etc).
Rogowski coil - Wikipedia
A Rogowski coil, named after Walter Rogowski, is an electrical device for measuring alternating current (AC) or high-speed current pulses. It sometimes consists of a helical coil of wire with the lead from one end returning through the centre of the coil to the other end so that both terminals are at the same end of the coil.
This paper provides a detailed guide for the design, fabrication, and installation of Rogowski coils as implemented at AFRLs Directed Energy Directorate, High Power Electromagnetics Division.
