  1. Anatomy of an electrical accident.

    Article - En anglais

    An electrical accident that happened in the fan room is analyzed based on site investigation, interviews, and laboratory examination.

    From the results, it is concluded that the fan motor contractor probably developed a phase-to-phase fault due to abnormal operation.

    As a result of the broken cam, the contractor control switch probably operated intermittently and rapidly, and caused the contactor to chatter.

    Without the arc-chute in place on the contactor, a phase-to-phase fault developed as ozone was created by the continuous arcing at the contactor contacts.

    The disaster is attributed to human error, poor maintenance, improper equipment design, and lack of training.
