1. Primary 2. Induces

If a fault occurs on a lateral, a ______________ may delay closing for a specific amount of time to give a ___________________ an opportunity to open.

1. Recloser 2. Sectionalizer

Describe a distribution system:

All of the components in a T&D system that allows power to flow from the substation to the consumer.

______________ can improve the efficiency of a distribution system.

Capacitors

What devices are typically used to interrupt the flow of electricity through a distribution line?

Circuit breakers, fuses, sectionalizer, recloser.

Which type of distribution layout could be used to ensure that critical needs customers, such as hospitals, do not experience an interruption of service.

Duplicate.

Capacitors:

Increases overall efficiency, electrical device that can accept a charge, store, and release it.

Describe- Loop: Radial: Duplicate: Spot Network:

Loop: Individual laterals run through specific regions of a service area and have the capability of rejoining the feeder further down the line. (Residential) Radial: Not immediately adjacent to feeder, service drops. (communities, offices, and industries) Duplicate: Feeds off two feeders. (Hospitals.) Spot Network: ^^^^^^^^^

List three elements common to most transformers.

Primary winding, secondary winding, and a metal core.

Surge arrestors:

Provides a safe flow path to ground for excess current flow caused by voltage surges.

__________________ is a process of isolation a section of a distribution system, while maintaining service to the majority of customers in the system.
