Demagnetisation fault detection in PMSM using zero sequence current components

open access: yesElectronics Letters, 2017
A demagnetisation fault detection method for a delta‐connected permanent magnet synchronous machine (PMSM) based on zero sequence current components (ZSCC) is proposed. The model of the delta‐connected PMSM with the demagnetisation fault is first established.

Systems engineering approaches to safety in transport systems

open access: yes, 2022
During driving, driver behavior monitoring may provide useful information to prevent road traffic accidents caused by driver distraction. It has been shown that 90% of road traffic accidents are due to human error and in 75% of these cases human error ...

A new leakage protection method for mine power network

open access: yesGong-kuang zidonghua, 2016
A new leakage protection method was proposed which was based on least-square matrix algorithm. In the method, zero sequence current signal of each brance is extracted on the basis of additional DC source system, and DC component of the zero sequence ...

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
