COORDINATED POWER SYSTEM PROTECTION
**************************************************************************
NOTE: The requirement for the studies in this
section depends on the complexity and extent of the
power system. Delete this requirement for: project
of limited scope; projects having protective devices
which are not adjustable or for which coordination
is not possible (standard molded case circuit
breakers); projects involving simple extension of
600 volt level service to a building or facility
from an existing transformer (750 kVA or less); or
projects involving simple extension of 600 volt
level service to a building or facility from a new
transformer (750 kVA or less).
The designer will be responsible for specifying the
requirement for fuses, circuit breakers, protective
relays, or other protective devices associated with
the project and depecting them on the drawings. The
protective devices should be selected and specified
to protect electrical power system conductors or
equipment against sustained overloads, in-rush
conditions, electrical faults, or other abnormal
power system or equipment operating conditions, in
accordance with TM 5-811-14, COORDINATED POWER
SYSTEMS PROTECTION and IEEE Std 242, and IEEE Std
141.
The complexity and extent of coordinated power
system protection depends on the type of buildings
or facilities or utilities required, on the load
demand of facilities, and on the quantity and types
of facilities to be constructed. Facilities having
a relatively-low power demand (e.g., 2500 kVA or
less) generally require protection of an incoming
aerial distribution line or underground,
medium-voltage feeder, low-voltage feeders to
individual items of equipment, or to power
distribution equipment, and branch circuits. More
complex projects such as facilities with generating
capacity, large motors, or larger load demands, will
require more detailed and extensive coordinated
power system protection.
