To survive in the present condition and have a fast recovering, it tries to invest in production plant with a limited capital and more especially for the corresponding electrical installations. It tends therefore to maximize the ratio reliability over capital expenditure and availability over capital expenditure. Study of reliability analysis of life time differential and basis, and an economical assessment in line with idea to eliminate one of the 150 kV overhead line circuit according to the value engineering techniques for Kosambi Baru – Grogol case will prove real economical advantage and perform an acceptable decrease in reliability and availability and an insignificant increase in operational expenditure, beside stated several requirements and later stage of the study which needed. This simple analysis consist to two part data analysis, the first is analysis which based on data and event idealization (an optimistic analysis), the second is analysis which based on average data of 150 kV overhead lines. The different view of reliability analysis could probably lead economical risk calculation due to differential of hazard rate (lambda), availability and life cycle, to expose the quantity of estimated CAPEX saving and compare two system in term of annual cost assessment and present value cash flow. The insulator washing policy, hot line maintenance and an operational expenditure differential will be discussed to show the impact due to mitigating the dust effect assumption and an additional solution for maintenance scheduled outages.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]High voltage transmission systems[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Availability,Capital Expenditure,Life Time,Operational Expenditure,Reliability[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
