definition of alternating current - (ANSWER)electric current which periodically passes through a regular
succession of changing values, both positive and negative
what is the unit of an alternating-current frequency? - (ANSWER)hertz
define the power factor of an alternating-current curcuit - (ANSWER)the ratio of the actual power to the
product of volts times amperes
PF=watts/VoltsxAmperes
describe the theory of operation of an electric transformer - (ANSWER)voltage must be stepped up and
then must be stepped down. the transformer is the apparatus used to make these changes
describe a typical electric system - (ANSWER)powerplant, transmission, transmission lines, substation,
distribution
what is a transmission line? - (ANSWER)a set of conductors energized at over 69,000 volts and
transmitting large blocks of electrical energy over relatively long distances
how do voltage levels of transmission, subtransmision, and distribution differ? - (ANSWER)transmission
circuits: 69kv-765kv, subtransmission
when is a direct current transmission line used? - (ANSWER)to transmit large amounts of power over
long distances or to interconnect two AC systems that are not synchronized
list of functions that can be accomplished in an electric substation - (ANSWER)switch generators,
equipment, and circuits or lines in/out of the system, change AC voltage from on level to another, or
changing AC->DC or DC->AC

list the component parts of the electrical distribution system - (ANSWER)(1) distribution substation, (2)
distribution feeder circuits, (3) switches, (4) protective equipment, (5) primary circuits, (6) distribution
transformers, (7) secondaries, and (8) services
describe a traditional distribution feeder circuit - (ANSWER)serve as a source to branch or primary
circuits and are often referred to as distribution main-feeder or express feeder circuits
what is a primary circuit? - (ANSWER)distribution circuits greater than 600 volts up to 69,00 volts are
often referred to as primaries by lineman
what is the purpose of a distribution transformer? - (ANSWER)to reduce voltage of the primary circuit to
the utilization voltage required to supply the customer
describe an electrical service - (ANSWER)the wire extending from the distribution transformer, adjacent
to the customers property to the customers premises are called a service
what is the purpose of an electric substation - (ANSWER)an electrical substation is an installation with
electrical equipment capable of interrupting or establishing electrical circuits and changing voltage,
frequency, or other characteristics of the electrical energy flowing in the circuits
equipment found in a typical substation - (ANSWER)power transformers
tap changing equipment
steel structures
lighting arresters
circuit switchers
SF circuit breakers
oil circuit breakers
air circuit breakers
