What relay protection is installed on the 35kV busbar
The standard protection scheme for these buses has been a high impedance bus differential relay. Interlocking and overcurrent differential protection can be implemented with any suitable overcurrent relay from GE Multilin, and performance has to be balanced in terms of speed and security against the reduced cost of protection. When an imbalance occurs, it. Busbar Differential Protection Definition: Busbar differential protection is a scheme that quickly isolates faults by comparing currents entering and leaving the busbar using Kirchoff's current law. In general, the main requirements for busbar. Historically, Pacific Gas and Electric Company (PG&E) has standardized on the double-bus single-breaker arrangement for major transmission buses (Figure 1). The single breaker double bus configuration. Literature review has shown that small distribution substations used for medium voltage make use of overcurrent relays to provide busbar protection and large substations make use of differential protection schemes. -
