ISA UTILITY SPECIALIST STUDY EXAM GUIDE ALL
QUESTIONS AND ANSWERS SURE A+
✔✔Fleet Tracking - ✔✔tracking the location & movement of vehicles using combo of
signals from GPS satellites & cellular towers
✔✔Graham Cover-Type Mapping - ✔✔establish a cover-type map using aerial imagery
in combo w tree species ID along transect lines or at randomly or systematically
selected points
✔✔Grid Work - ✔✔distribution cycle work performed within a specified geographic
boundary
✔✔Ground Wire - ✔✔common return path for an electrical or physical connection to the
earth
✔✔Grounded - ✔✔electrically connected to the earth, providing path for the flow of
electricity to prevent accidental energizing
✔✔Grounding - ✔✔act of creating path for electric current to reach earth(earthing)
✔✔Ground-to-Conductor Clearance - ✔✔clearance or distance btwn energized
conductors & the ground
-US----specified by National Electrical Safety Code(NESC)
,✔✔Guy Wire - ✔✔wires used for support in places such as where a line turns or dead-
ends
-areas of high winds or anticipated stress points
✔✔Half-Life - ✔✔amount of time ti takes half of the quantity of a substance to dissipate,
indicates herbicide persistence
✔✔Hazard Tree - ✔✔tree that has been assessed & found to be likely to fail & cause an
unacceptable degree of injury, damage, disruption
-hazard tree poses a high or extreme level of risk
✔✔Heading Cut - ✔✔cutting a shoot or branch back to a bud, stub, small lateral branch
-cutting an older branch/stem back to a stub in order to meet structural objective
✔✔Heavy Wet Snow - ✔✔snow w a water equivalent ratio of 10:1 or less
✔✔Herbicide - ✔✔specialized chem substance used to kill plants by interfering w critical
botanical biochemical pathways
✔✔Hertz(Hz) - ✔✔number of cycles or revolutions of spinning generation magnets per
second
-AC periodically varies in amplitude in conjunction w spinning generation magnets,
intensifying from 0 to max value in positive direction back to zero & minimum value in a
negative direction before returning to zero
-changing intensity & direction of AC is graphed in a sine wave
-time it takes for a magnet to complete revolution is a cycle
✔✔High-Reliability Organization - ✔✔group that takes systems approach to safety,
recognizing that humans are imperfect & that errors have to be considered in context of
system in which they occur
✔✔High-Voltage Lines - ✔✔lines w voltages greater than 750 V
✔✔Hotspotting - ✔✔limited tree work is schedules on a specific are of the network
where shorts/outages are occurring
✔✔Hurricane - ✔✔regional term for Western Hemisphere tropical cyclones w wind
speeds 74 mph+
✔✔Hydration - ✔✔condition of having adequate fluid in body tissues
✔✔Hydroelectric - ✔✔electric generation using water
, ✔✔Incident Command System(ICS) - ✔✔standardized on-scene incident management
approach allows responders to adapt an integrated organizational structure equal to the
complexity of & that meets the demands of a single incident or multiple incidents, w/o
being hindered by jurisdictional boundaries
✔✔Impedance - ✔✔sum of resistance
-inductive resistance & capacitive resistance
✔✔Imminent Threat - ✔✔vegetation condition that could cause damage or interruption
of service to overhead energized facilities or pipelines at any moment
✔✔Incident - ✔✔unplanned, undesirable event that could result in unintentional injuries
or prop damage
✔✔Incompatible Plant Species - ✔✔plant species that are inconsistent w the use of a
site
✔✔Indirect Contact - ✔✔touching a conductive object in contact w an energized fixture
✔✔Inductance - ✔✔electrification of wire by passing it thru a moving electromagnetic
field
✔✔Inductive Reactance - ✔✔reactance is caused by a small amount of load lost when
a current flows into. coil(those in xfmr)
✔✔Initial Clearing - ✔✔VM perspective, clearing a ROW prior to construction or 1st
work clearing an overgrown ROW
✔✔Insulator - ✔✔material w poor conductivity------fiberglass, glass, polymers, porcelain
-used to separate energized conductor from poles or other objects or structures that
must not be energized
✔✔Integrated Pest Management - ✔✔use of all available pest control methods to keep
pest pops below acceptable levels
-cultural, bio, chem, physical, genetic
✔✔Integrated Pest Management(IPM) - ✔✔sys of managing plant Community based in
IPM, managers ID compatible & incompatible veg----consider action thresholds,
evaluate control methods & select/implement control methods based on anticipated
effectiveness, ES impact, site characteristics, safety, security, economics, etc
✔✔Interconnection Reliability Operation Limit(IROL) - ✔✔value derived from or subset
of System Operating Limits, which if exceeded could expose widespread area of Bulk
Electric System to instability, uncontrolled separations or cascading outages
