Self-Error Correcting Method for Magnetic-Array-Type Current Sensors in Multi-Core Cable Applications
Xiaohu Liu, Keyu Hou, Kang Ma +7
Data-driven methods enable online assessment of error states in magnetic-array-type current sensors, and long-term measurement stability can be enhanced through further self-error…
An Approach for Restoring Magnetic Field Uniformity in Openable BIPM-Type Kibble Balance Magnets
Nanjia Li, Weibo Liu, Yongchao Ma +3
The Kibble balance realizes the kilogram by linking mechanical and electrical quantities via a magnet system. In an improved BIPM-type magnet design by Tsinghua University, an open…
An Evaluation of External Magnetic Flux Error in Magnet-Moving Kibble balances
Yongchao Ma, Wei Zhao, Songling Huang +1
The magnet-moving measurement scheme in Kibble balances avoids displacing force-sensitive components, such as the weighing cell, and enables a broader magnetic profile measurement…
Metering Error Estimation of Fast-Charging Stations Using Charging Data Analytics
Kang Ma, Xiulan Liu, Xi Chen +5
Accurate electric energy metering (EEM) of fast charging stations (FCSs), serving as critical infrastructure in the electric vehicle (EV) industry and as significant carriers of ve…
Compressive Sensing Empirical Wavelet Transform for Frequency-Banded Power Measurement Considering Interharmonics
Jian Liu, Wei Zhao, Shisong Li
Power measurement algorithms based on Fourier transform are susceptible to errors caused by interharmonics, while wavelet transform algorithms are particularly sensitive to even ha…
