The cost of buying the site and preparing it for a substation

(a)  

The cost of terminating transmission at the site

(a)  

The transformer and all metering, control, oil spill containment, fire prevention, cooling, noise abatement, and other transformerrelated equipment, along with typical bus work, switches, metering, relaying, and breakers associated with this type of transformer and their installations

(a)  

The cost of beginning distribution at the substation, which includes getting feeders out of the substation

(a)  

A device for protecting an electrical apparatus from damage by lightning.

(a)  

A switch that isolates a circuit or one or more pieces of electrical apparatus after the current has been interrupted by other means.

(a)  

A combination of a switch to disconnect the circuit and a fuse to shut the circuit off in the event of a problem.

(a)  

It is made of three sets of primary and secondary windings, each set wound around one leg of an iron core assembly.

(a)  

A type of circuit breaker that uses insulating oil as a dielectric medium to quench the arc and break the circuit safely.

(a)  

A device that can stop the flow of electricity around a circuit by switching itself off if anything goes wrong.

(a)  

A terminal where buses arrive and depart.

(a)  

Used in high voltage energy transmission systems to control the voltage during load variations

(a)  

To the limit of the defined values the voltage has to the ground in every part of the electrical system.

(a)  

A relay whose function is to detect defective lines or apparatus or other power system conditions of an abnormal or dangerous nature and to initiate appropriate control circuit action.

(a)  

Also known as wave trap, or high-frequency stopper, is a maintenance-free parallel resonant circuit, mounted inline on high-voltage (HV) AC transmission power lines to prevent the transmission of high frequency (40 kHz to 1000 kHz) carrier signals of power line communication to unwanted destinations.

(a)  

Electrical instruments used in transmitting electrical power from one circuit to another without changing the frequency.
