Unit of energy use over time
used to bill electric
customers
What is a kilowatt hour
(kWv)?
Electric current that reverses
direction at regular intervals
What is an alternating
current (AC)?
The amount of power
required by consumers
What is the load?
Measure of electric energy
that electrons can release or
acquire when they move
between conductors
What is voltage?
Degree to which an electrical
component resists the flow
of current.
What is resistance?
Land set aside for
distribution towers, poles,
lines and other facilities.
What is right of way?
Provides a path for
unintended power to travel
down a pole and into the
earth
What is a ground wire?
Nonconductive materials
used to support the power
line at its attachment points
and reduce sway
What are insulators?
A piece of equipment
designed to protect
components in an electric
distribution system in the
event of a system failure.
(Can be re-set.)
What is a distribution circuit
breaker?
Adjusts voltage levels in
distribution circuits to
maintain a constant voltage
level in the system.
What is a distribution circuit
regulator?
Located along both the
transmission and distribution
system routes and contains
transformers to step down
power and re-route it.
What are substations?
A structure within the
substation yard that houses
electric power distribution
monitoring and control
equipment.
What is the control house?
A piece of equipment in
which the primary winding
has more turns than the
secondary winding. Used to
change voltages.
What is a step down
transformer?
Connects the electrical
power output of a
distribution substation with
the input terminal of a
primary circuit.
What is a distribution feeder
circuit?
Structure found at
distribution substations that
contains switches to route
power out of the substation
What is a distribution bus?
Interconnected lines that
move electric power to its
end user—the customer
What is the electric power
distribution system?
Power lines are called this-probably because electricity
flows along the path of least
resistance.
What are conductors?
Consists of a system of
distribution line that are
connected to only a single
power source
What are radial distribution
networks?
Circuit carrying power from
a substation to a local
distribution service area
What is a primary circuit?
Can be found in either a web
or a loop configuration
What is an interconnected
distribution network?
Device that measures the
amount of power consumed
What is an electric meter?
Conversion of high voltage
electricity to lower voltages
by transformers
What is stepped down?
Wires connecting a
distribution transformer to a
customer’s house
What is a service drop?
Using devices that can read
electric meter data
What is automatic meter
reading (AMR)?
Wireless automatic
transmission of data, usually
for remote monitoring
What is telemetry?
