Busbar Heat Shrink
Introduction
Busbar protection is a protection scheme meant to protect the busbar from electrical fault. Various feeders are connected to a busbar through circuit breaker in any of the bus configuration viz. double busbar arrangement or one-and-half breaker scheme. The main purpose of this busbar is to increase the reliability of power system by maintain the evacuation of power in case of tripping of any feeder due to fault.
The requirements of protection schemes for HV overhead transmission lines are:
- The electric protection system must be able to detect all faults on the protected line.
- The protection system must be able to discriminate between faults on the protected line and faults on adjacent lines, buses, transformers.
