R& M OF SUBSTATION AND TRANSMISSION LINES:-
To cope up with growing demand for power, construction of new Transmission Lines and Sub-Stations is always a difficult proposition due to various factors like high initial investment, approvals, ROW and environmental concerns. R&M and upgradation of existing projects is one of the cost effective alternatives to increase the power transmission capabilities and reduce losses of a Transmission System. The transmission line and substation voltage upgrading offer considerable advantages. The conversion of transmission lines and substations to higher voltages has emerged as a viable alternative in meeting load growth or transmission requirements. This approach offers several advantages. In addition to the practical aspects such as use of available Right of Way (ROW) and substation site (i.e better utilisation of existing transmission system), the economic advantages may be of considerable interest, particularly if some of the original foundations, structure, or equipment can be used with minimal modifications. The economic advantage is also linked with reduction in losses
