With the increasing demand for precise condition monitoring and diagnosis of 11 gas-insulated switchgears (GIS), it has become a challenge to improve the detection sensitivity of 12 partial discharge (PD) induced in the GIS spacer. This paper deals with the elimination of the 13 capacitive component from the phase resolved partial discharge (PRPD) signal generated in GIS 14 spacer based on the ...

With the growth of world’s population and faster-developing industries, larger amounts electric energy are needed [...]

The housing of zinc oxide lightning arresters are playing major role for discharging the lightning surges. Previously porcelain and silicon rubber housings were mainly used depending on the atmospheric conditions but in practice a lot of problems are faced with these housing. Hence this paper presenting the ZnO blocks performance characterizes with different dielectrics such as air, transformer...

BACKGROUND AND PURPOSE Recent reports describe a high rate of thromboembolic events related to Guglielmi detachable coil (GDC) use in the treatment of cerebral aneurysms. The purpose of this study was to investigate electrolysis-related changes of blood as a potential cause of thromboembolic complications associated with GDC use. METHODS For in vitro observations, 15 GDCs (10 conventional coi...

Since Zwilling and co-workers first introduced the electrochemical anodization method to prepare TiO2 nanotubes in 1999, it has attracted a lot of researches due to its outstanding gas response and selectivity, making it widely used in gas detection field. This review presents an introduction to the sensor applications of TiO2 nanotube arrays (TNTAs) in sulfur hexafluoride (SF6)-insulated equip...

In this work, we present the application of exergy analysis in the evaluation of the ethanol steam reforming (ESR) process in a catalytic membrane reactor (CMR) containing Pd-Ag membranes sandwiched by PdRh/CeO2 catalyst to produce fuel cell grade pure hydrogen (no sweep gas). ESR experiments were performed at T=873-923 K and P=4-12 bar. The fuel was a mixture of ethanol and distilled water wit...

Abstract. Close-Range Photogrammetry (CRP) technology advanced rapidly along with the development of camera sensors. CRP has many advantages over other methods in terms technical data acquisition, product quality, and cost. Because these advantages, method can be used various applications. In this study, is to monitor deformation SF6 Gas Insulated Line (GIL) object between two substations Indon...
