New 550-kV Gas-insulated Switchgear
OVERVIEW: Hitachi has developed smaller and more reliable gas-insulated switchgear (GIS) in response to demands for lower costs and stable power supplies. Reliability of this GIS was improved and the enclosure diameter was reduced in order to minimize the installation space by using new analysis techniques and rationalization in insulation design and in temperature rise criteria. Furthermore, t...
متن کاملStatus Review on Gas Insulated Switchgear Partial Discharge Diagnostic Technique for Preventive Maintenance
Gas insulated switchgear (GIS) plays a vital role in high voltage transmission of electrical energy due to its advantages of high reliability and performance, compact in dimensions and outstanding compatibility with the environment. It uses sulphur hexafluoride gas as its insulant and coolant because of its high dielectric strength and excellent arc quenching ability. Gas insulated switchgear i...
متن کاملFeasibility Assessment on Vacuum Insulated Switchgear
To find feasible alternatives to the use of SF6 in medium voltage switchgear equipment, AREVA T&D and Tsinghua University has started a cooperation to investigate the feasibility of using vacuum. This paper focused on three main points of the design of the Vacuum Insulated Switchgear (VIS): the maintainability of vacuum system, the insulation performance, and the thermal behavior under operatin...
متن کاملChemical by-Product Diagnostic Technique for Gas Insulated Switchgear Condition Monitoring
Chemical by product diagnostic technique is an efficient, cost-effective and reliable diagnostic technique for gas insulate switchgear condition monitoring in view of its high sensitivity and antiinternal and external electromagnetic interference and noise. In this research paper, coaxial simulated gas insulated switchgear chamber and four different types of artificial defect were designed to c...
متن کاملUHF Signal Processing and Pattern Recognition of Partial Discharge in Gas-Insulated Switchgear Using Chromatic Methodology
The ultra-high frequency (UHF) method is widely used in insulation condition assessment. However, UHF signal processing algorithms are complicated and the size of the result is large, which hinders extracting features and recognizing partial discharge (PD) patterns. This article investigated the chromatic methodology that is novel in PD detection. The principle of chromatic methodologies in col...
