Electrical Equipment Isolation

Electrical equipment isolation or switching can be relatively straightforward or extremely complicated depending upon the complexity of the electrical distribution system. Regardless of its size or the number of switching steps involved, switching should be done following a written switching order or proce dure. Planning switching operations provides an opportunity to consciously address all aspects of the work in a way that incorporates the appropriate personnel and their experience as well as the consideration of the risks associated with the switching operation and their mitigation. This article discusses the successful approach of developing and executing electrical equipment switching procedures at two major petrochemical organizations.
