11-1
INTRODUCTION .
11-1.1
Consider surge protection as part of the facility design criteria. The extent to
which surge protection will be required depends on the facility's mission and the facility
occupant's reliability target. Surge protection should be applied to the following types of
facilities:
Medical treatment facilities.
Air navigation aids and facilities.
Petroleum, oil, and lubricant (POL) storage and dispensing facilities.
Critical utility plants and systems.
Communication facilities and telephone exchanges.
Fire stations, including fire alarm, fire control, and radio equipment.
Critical computer automatic data processing facilities.
Air traffic control towers.
Base weather stations.
Surveillance and warning facilities.
Command and control facilities.
Weapon systems.
Security lighting systems.
Mission, property, and life support facilities at remote and not readily accessible
sites, such as split-site aircraft warning and surveillance installations.
11-1.2
Consider surge protection for all types of facilities located in the following
areas:
In regions with a high lightning strike probability (refer to IEEE C62.41, IEEE
Recommended Practice on Surge Voltages in Low Voltage AC Power Circuits).
