Low‐frequency performance of openable flexible double‐loop Rogowski coil
IET Science, Measurement & Technology, 2021 Double‐loop Rogowski coils have become increasingly popular in the market because of their high sensitivity and flexible usage compared to their extended single‐loop coils. Due to the high number of turns (thousands) and its small turn diameter (

IET Power Electronics, Volume 19, Issue 1, January/December 2026.This paper proposes a non‐contact method for measuring the turn‐off time of insulated‐gate bipolar transistor (IGBT) devices in modular multilevel converters (MMC) submodules, using the decay of load‐side common‐mode current. The technique leverages existing current‐sensing infrastructure and avoids intrusive modifications, enabling real‐time ...
