NLC Electrical Systems Exam Questions And
Complete Answers
alternating current - answer alternating current means that the flow of electrical energy
changes Direction at a certain rate
conductor bundles - answer a term used to indicate more than one conductor per phase
conductor bundles or bound on transmission lines and can be 2 3 or 4 bundle
Delta Systems - answer a Delta distribution power line has only three phases. The term
Delta refers to how the substation Transformers which are the source of the distribution
line are wired
distribution - answer lines that deliver power directly to the customer distribution lines
most commonly operate between 2 KV and 34.5 KV
distribution substation - answer substations that are used to step voltage down from sub
transmission levels to distribute levels. distribution circuit leave these stations and
deliver power directly to the customers
generation stations - answer where energy from coal, oil, gas, steam, water, and atom
are converted into electrical energy
generation substation - answer sub station located at the generation station that step
voltage up and connect to the transmission system
kilovolt - answer kilovolt is metric for 1000
Network circuit design - answer circuits and metropolitan areas where the primary and
secondary circuits are tied together in a grid
phase - answer a term used referring to an energized conductor. A distribution Main
Line feeder has three phases
primary - answer the high-voltage portion of a distribution power line
radial circuit design - answer independent distribution circuits that radiates from the
substation into the service area. There is no other source should a section of the line
need to be cleared
radial tie circuit design - answer circus that are tied two circuits from the same
substation or another substation. Power can be supplied from other circuits should a
section of line needs to be cleared
secondary - answer the low voltage portion of a distribution power line that runs from
pole to pole on overhead systems or pad mat to pedestal and underground systems
