Literature review has shown that small distribution substations used for medium voltage make use of overcurrent relays to provide busbar protection and large substations make use of differential protection schemes. This technical article explains a busbar theory at the distribution. Busbars in power systems are the location where transmission lines, generation sources, and distribution loads converge. Because of this convergence, short circuits located on or near the busbar tend to have very high magnitude currents. Current Differential Protection: This protection method connects CT secondaries in parallel and. Essentially, bus protection is a specific covering of differential security designed to find defect come immediately on the busbars - the conductors that collect and distribute electrical energy. Busbar protection is critical for the safe and reliable operation of a power system.
