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 ...

In this article, a novel SH guided wave EMAT with periodic solenoid coils (PSCs) and a single magnet (referred to as the PSC EMAT) was developed. The design methodology for the PSC EMATs was presented ...
