Lightning and Power Surge Investigations

Electrical systems, components, appliances, and equipment, etc. can be affected in adverse ways by lightning and/or electrical power surges. YAES engineers have the knowledge, training and experience to evaluate all types of electrical system failures resulting from lightning or power surges and the ability to distinguish between the two events. We combine our experience in electrical failure analysis with our ability to evaluate credible historical weather data and identify critical physical evidence in determining the cause of lightning and power surge events. Commonly investigated electrical systems include electrical distribution systems (split-phase residential, three-phase commercial and industrial), appliances, smart home/home automation systems, industrial equipment, radio antennae towers, exterior lighting, HVAC equipment, elevators, generators, video surveillance systems, PBX telephony systems, digital signage and score boards, solar equipment, lightning protection systems, marinas, and boats.
