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.
