A Flexible Planarized Biconical Antenna for Partial Discharge Detection in Gas-Insulated Switchgear
IEEE Antennas and Wireless Propagation Letters, 2022This letter proposes a new ultrahigh frequency (UHF) flexible planar biconical antenna design method for partial discharge (PD) detection in gas-insulated switchgear. Continuous transverse branching increases the electrical length to expand the bandwidth

2022 IEEE International Conference in Power Engineering Application (ICPEA), 2022
Electromagnetic waves on Partial Discharge (PD) that occur in Gas Insulated Switchgear (GIS) have frequency value in Ultra High Frequency (UHF) range (300 MHz – 3 GHz). So that, PD waves in GIS can be detected using UHF Antenna sensor. In this paper, the

Separation of Partial Discharge Faults in Metal-clad Switchgear Based on Pulse Shape Analysis
Electrical Insulation Conference, 2022Switchgear is an integral part of power systems network. Any fault occurring in switchgear may leads to significantly long outage duration and the affected load, or area, can be enormously large.

Thermal simulation of switchgear
Proceedings of the Forth-Seventh IEEE Holm Conference on Electrical Contacts (IEEE Cat. No.01CH37192), 2002In development of low voltage switchgear, proper thermal design becomes more and more important to provide safe function and reliability in spite of miniaturization and increasing performance demanded of modern devices. Due to the high complexity of heat generation and loss processes it is not easy to predict the thermal behavior of devices under ...
