Investigations to Identify Electrical Ignition of Fires


In power systems that comply with best practices, electrical ignition theoretically remains possible only when there is an accident. Generally, if there is a fire, it is not easy to identify its origin because everything is destroyed. In an effort to assist fire investigations, this article suggests a deductive
approach in testing possible hypotheses on electrical ignition.
It analyzes the different evolutionary scenarios that characterize faults in primary distribution circuits versus branch distribution circuits. As an application, we illustrate a case study of the fire ignition that affected two fabric storage rooms and an adjacent transformer substation.

A technical first level for accident trials


This article deals with the known contrast between what might be called the certain logic required by judicial proceedings and the uncertain logic of engineering evaluation. For accident cases that require a risk assessment, this study offers a solution to adopt a division of accident-related trials into two different levels: 1) an engineering level, in which a technical analysis of the accident’s causes is performed, followed by 2) the traditional judicial level.
A technical level might better support the formulation of a rational verdict by providing a more exhaustive analysis of an accident’s causation and the parties’ responsibilities. It might also provide criteria to improve safety and prevent accidents in the workplace and in the operation of electrical installations.

Functions and duties of the forensic electrical engineer

Forensic engineers have several duties, in some cases to be performed in conflictual situations (e.g. depositions). The competencies of the forensic electrical engineer include the knowledge of engineering standards and best practices, familiarity with applicable laws and regulations, as well as wise decision making. In this paper, functions and duties of the forensic electrical engineer preparing for a trial are discussed and quantitative methods of technical evaluation are proposed. Around the world, institutions establish and define the competencies of the forensic engineer, and promote the advancement of the forensic science through conferences, and publications. To resolve the historical dichotomy between the logic of the “certainty” required by the judicial outcome of proceedings, and the logic of the “uncertainty” of the engineering, this paper suggests utilizing the subdivision of accident-related trials, when a risk assessment must be provided, into two levels; a junior “engineering” level (which may be public is some jurisdictions, confidential in others), followed by a senior level or formal trial, might together better support the formulation of the verdict by providing a more exhaustive analysis of the accident causation, and parties’ responsibilities. Key words: forensic science, logic of certainty and uncertainty, fuzzy logic, technical investigation, cindynic model.
