  • Protection of busbars in distribution boxes

    Protection of busbars in distribution boxes

    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. Busbar Differential Protection Definition: Busbar differential protection is a scheme that quickly isolates faults by comparing currents entering and leaving the busbar using Kirchoff's current law. Its purpose is to conduct a substantial current of electricity.
