Bus bar Protection. The high speed low impedance type bus bar differential protection, which is essential to minimize the damage and maintain system stability at the time of bus bar faults, shall be provided for 400 kV, 220 and 132 kV buses. Duplicated bus bar protection is envisaged for 400 kV bus-bar protection. Bus bar protection scheme shall be such that it operates selectively for each bus and incorporates the necessary features required for ensuring security. Bus Bar protection system for new substation shall be de-centralized (distributed) type. The scheme shall have complete bus bar protection for present as well as envisaged future bays i.e. input / output modules for future bays for the bus sections under present scope and PUs shall be provided by the respective bay owners. In case the bus section is provided, then each side of bus section shall have separate set of bus-bar protection schemes. For existing substations, the existing bus bar protection shall be augmented as per requirement.
