Review of Substation Busbar Component Reliability
This chapter focusses on the design implications of connecting or rigid, single or bundled conductors to HV equipment with connectors/clamps, either bolted, welded or compressed.

Such a system consists of two bus-bars, a "main bus-bar and a "spare" bus-bar (see Fig. In Simple words, a bus-bar is a common connection point or a node for multiple incoming and outgoing circuits such as power lines or feeders. Designing a substation involves not only the visible equipment and ratings but also the less apparent factors—operational. This chapter focusses on the design implications of connecting or rigid, single or bundled conductors to HV equipment with connectors/clamps, either bolted, welded or compressed. It is important that the engineer's plans remain as flexible as possible during substation layout to allow for unforeseen difficulties as designs progress. Bus Couplers are switching devices, which are often circuit breakers, that are utilized to connect two (or) more busbars that are located within a substation. What is a Bus Coupler? Why do Substations use Bus Couplers? Where do Bus Couplers fit in Busbar Schemes? Unlike feeders (or) incoming lines.
