The configuration of the connection arrangement for a new generator system must be designed so that no more than the co-optimised maximum dispatch from a Generator will be disconnected
Large electrical generators happen to generate AC naturally, so conversion to DC would involve an extra step. Transformers must have alternating current to operate, and we will see that the

Single-phase sectionalizing equipment may be installed on the main circuit past the applicant location, or on radial circuits that tap the main circuit between the source substation

Large strings of insulators are used at substations and at other points along the power distribution system to isolate the current carrying conductors from their steel supports or any other ground mounted equipment. Insulators may be made of porcelain, rubber or a thermoplasticSee more on electrical-engineering-portal

Electric power may flow through several substations between generating plant and consumer, and may be changed in voltage in several steps.
Transmission substations integrate transmission lines into a network with multiple parallel interconnections, so that power can flow freely over long distances from any generator
Each generator and feeder may be connected to either bus-bar with the help of bus coupler which consists of a circuit breaker and isolators. In the
There are two main options for a Generation Interconnecting Facility to connect to the transmission system: connection to a substation (new or existing) or connection to a
Each generator and feeder may be connected to either bus-bar with the help of bus coupler which consists of a circuit breaker and isolators. In the scheme shown in Fig. 3, service is interrupted
