Lightning Damage
Correlation is not Causation
- • On Average there are 60 Thunderstorms per Year in Illinois. [80 in Southern Illinois]
- • That means [60/365] 1/6 of the time that an electronic device fails it will be during a Thunderstorm.
Evidence of Lightning Damage
- • Evidence of High Voltage Surge (e.g. flashovers at terminals and relay gaps)
- • High voltage damage to a capacitor (usually “run” capacitor)
- • Verification of high voltage surge with powerr company
- • High voltage damage to delicate circuit boards
- • In motors – evidence that winding is grounded out. (usually run vs. start winding)
