Gas Insulated Switchgear tanks detecting

Gas Insulated Switchgear tanks detecting

Gas insulated switchgear is commonly used in substations and the development of gas insulated transformers allows complete integration of substation equipment with resultant space and cost savings. Gas insulated transformers (GITs) have been in use since the 1960s, but use has been restricted due to higher costs and other reasons.

  • Mechanical defects diagnosis for gas insulated switchgear

    Mechanical faults are major fault types in gas insulated switchgear (GIS). The vibration and acoustic signature provide valuable health indicator for GIS. This paper proposes a novel mechanical defect detection and identification approach for GIS using acoustic imaging. The vibration modals of a three-phase-in-one-tank GIS bus tube under different natural frequencies are investigated.Author: Qing Xiong, Jinfei Zhao, Ziqing Guo, Xianyong Feng, Hanchao Liu, Lingyu Zhu, Shengchang Ji
