Split-core PCB Rogowski coil designs and applications for protective relaying

2003 IEEE PES Transmission and Distribution Conference and Exposition (IEEE Cat. No.03CH37495), 2004
Printed circuit board (PCB) Rogowski coils can be designed as non-split-core styles with different shapes such as circular, oval, or rectangular. They can also be designed in split-core style for installation without the need to disconnect a primary or secondary conductor.

DC-Link Capacitance Estimation for Power Converters Using Integrated PCB Rogowski Coils

IEEE Transactions on Instrumentation and Measurement
Capacitance is a key electrical parameter of capacitors in power electronic converters, and its estimation is important for the stable operation of the converters. This article presents a small printed circuit board (PCB) with Rogowski coils for measuring ripple voltage rate (dv/dt) and ripple current in an online and contactless manner to estimate the

Design and test of a PCB Rogowski coil for very high dI/dt detection

2012 15th International Power Electronics and Motion Control Conference (EPE/PEMC), 2012
This study proposes the bespoke design of a printed-circuit-board (PCB) integrated Rogowski coil to detect very high dI/dt's in an IGBT non-destructive tester. During reverse bias safe operating area (RBSOA) tests of an IGBT, failures of the transistor or of the freewheeling diode can lead to excessive dI/dt in the circuit.
