This paper presents the analysis of lightning arrester energy due to back flashover and shielding failure phenomena in a 132kV transmission line in Malaysia. The transmission line, towers and surge arresters were modeled using PSCAD/EMTDC... more
This paper presents analysis of lightning arrester energy due to back flashover and shielding failure for the purpose of installing transmission line arrester (TLA). This study simulated, analysed and validated with the installed... more
Traction insulators are solid core insulators widely used for railway electrification. Constant exposure to detrimental effects of vandalism, and mechanical vibrations begets certain faults like shorting of sheds or cracks in the sheds.... more
This paper presents a study on flashover patterns due to double tripping using EMTP software. The simulation was performed on a 132 kV line double circuit for economic installation of transmission line arresters (TLAs). The simulation... more
Surgearresters areequipments usedforthepower electrical systems protection. Theylimit thevoltage level during the occurrence ofswitching andatmospheric surges. A surge arrester failure cancause theequipments insulation breakdown... more
Investigation of the cause of repeated tripping of a 400 kV, AC transmission line has been reported in this paper. Failure of insulation strings in the months of December and January in a small length of the 400 km long line were caused... more
The flashover characteristics of an insulator bridged high voltage vacuum gap can play an important role in the overall performance of a high voltage device, for example in the extreme environments of high energy particle accelerators.... more
