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)
