Lightning Pritection Flashcards
State 3 effects of lighting
Generation of heat
Generation of mechanical forces
Generation of voltages
Name the 4 Main parts that make up a lighting protection system
Air termination
Down conductors
Earth electrodes
Bonding to prevent side flashing
What are air terminations in relation to lightning systems
This is the part the lightning strike comes into contact with first (steel rods)
How do u prevent side flashing
All metal work on or around a building must be bonded to the lightning protection system
Name 3 reasons why side flashing might happen
Faulty lighting protection system
Corrid joints on the down conductors leading to a high impedance
Incorrect routing of lighting conductors
Points to consider when designing a lighting protection system
Number of lightning strikes a year in this area
The size of the building
What is being stored in the building
Location of the building
The materials in which the building is made off
3 effects of over voltage on dc equipment
Damage to parts
Loss of data
Expenctive to replace
