Distribution

In a distribution transformer the ________________ winding receives electricity at a distribution voltage and ______________ a voltage in the secondary winding at a different value.

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.

Sectionalizing

Primary distribution voltage is applied to a distribution line by a ________________ transformer.

Substation

On a typical voltage regulator, _____________________ indicates regulated voltage applied by the regulator to the distribution system.

Tap position

A transformer is an electrical device that can change the value of __________________.

Voltage

If a fault occurs on a lateral, a circuit breaker may remain _______________ for a specific period of time to allow a fuse to open, isolating the faulted lateral.

closed

Before any work is done on a capacitor, personnel should follow the proper procedures for ____________________ the capacitor.

discharging.

A voltage regulator:

it regulates the voltage to a certain value

In a typical distribution system, ___________________ voltage is supplied to by a substation bus.

primary

Both surface transformers and pad-mounted transformers are used in __________________ distribution.
