Novel Busbar Protection Scheme for Impedance-earthed Distribution
Abstract—Due to the vast number of substations at the distribution level and increased costs of differential busbar protection, DSOs are in search of cost-effective protection schemes for busbar
BUSBAR PROTECTION
A busbar differential protection is characterized by its protecting zones, which refer to bus segments being isolated by circuit breakers in case of busbar faults.
Busbar Protection | Differential Protection | Protection of Lines
If a fault occurs on a busbar, considerable damage and disruption of supply will occur unless some form of quick-acting automatic protection is provided to isolate the faulty busbar.
