Busbar Protection - Differential and Frame Leakage Protection
WebBusbar protection is a safety scheme or technique designed to prevent the damage or destruction of a busbar. It is also used to cut off the power supply to the busbar in case of an overload or short circuit. A busbar protection scheme is a combination of various safety devices that are used together to protect a busbar. Webinternal bus fault. The normal rating of a bus conductor is from 1000-3000 A and a typical number of lines to a certain bus zone is 6-12 L. For the largest installations 2, 4 and 6 relay zones may be installed. Fig. 1 Single-bus one-zone with bus section switch normally closed Single bus one-zone The most simple and reliable installation is WebABB's busbar protection is designed for phase-segregated short-circuit protection, control, and supervision of single busbars.
