When reversed phase occurs in between a power substation transformer and an in-station high voltage switch gear or between in-station high voltage switch gears, the high-voltage power busbar bridge can be disposed between the power. When reversed phase occurs in between a power substation transformer and an in-station high voltage switch gear or between in-station high voltage switch gears, the high-voltage power busbar bridge can be disposed between the power. The utility model discloses a high-voltage power busbar bridge with reversible phase sequence, which comprises a bus tray which is a space structure with an upper layer, a middle layer and a lower layer. Each layer is provided with a left bus duct, a middle bus duct and a right bus duct in. During the normal operation when the bus bars are running separately with the interconnector breaker open, its OK, however when one of the transformer is out of service, and we have to close the interconnector breaker, the previosuly Red phase on, say, GT5 will now be Blue phase from GT3, in my. The reverse busbar protection is a cost-effective solution for the accelerated clearance of busbar faults in distribution systems. It can only be applied on single busbars with a fixed direction of power flow and fault current flow. In picture 3, a typical application is shown. For this.

This manual and its guidelines should be shared with operators and engineers associated with the owner/purchaser to ensure that the switchgears. This technical article as explained by BHEL deals with automatic bus transfer scheme, used in medium voltage switchgear of thermal power stations, which is required for transferring load from the unit transformer bus to the station transformer bus and vice versa.
