Forensic electrical engineer

Forensic electrical engineering is a branch of forensic engineering, and is concerned with investigating electrical failures and accidents in a legal context. Many forensic electrical engineering investigations apply to fires suspected to be caused by electrical failures. Forensic electrical engineers are most commonly retained by insurance companies or attorneys representing insurance companies, or by manufacturers or contractors defending themselves against subrogation by insurance companies. Other areas of investigation include accident investigation involving electrocution, and intellectual property disputes such as patent actions. Additionally, since electrical fires are most often cited as the cause for "suspect" fires an electrical engineer is often employed to evaluate the electrical equipment and systems to determine whether the cause of the fire was electrical in nature.

The ultimate goal of these investigations is often to determine the legal liability for a fire or other accident for purposes of insurance subrogation or an injury lawsuit. Some examples include:

Forensic electrical engineers are also involved in some arson and set-fire investigations; while it is not common for arsonists to cause electrical failures to ignite fires, the presence of electrical appliances and systems in many fires scenes often requires them to be evaluated as possible accidental causes of the fire. Some electrical means of ignition, when discovered, are fairly obvious to an origin and cause investigator and most likely do not require consulting with a forensic electrical engineer. (Note that "arson" refers specifically to a criminal act, subject to criminal prosecution; a more general term is a "set fire". A homeowner setting a fire deliberately in order to defraud an insurance company might be prosecuted for arson by a government body; however, the insurance company would concern itself only with denying the insurance claim, possibly leading to a civil lawsuit.)

Patent disputes may also require the expert opinion of an electrical engineer to advise a court. Issues in conflict may include the precise meaning of technical terms, especially in the patent claims, the prior art in a particular product field and the obviousness of various patents.
