A STUDY OF HIGH INTERRUPTING CAPACITY EQUIPMENT AND SYSTEMS FOR CLASS 1 HAZARDOUS (CLASSIFIED) LOCATIONS

摘要

There are numerous methods of handling high fault currents in the modern industrial facility. When it comes to hazardous locations however, questions abound over the equipment and/or systems required to survive these conditions without causing ignition of the surrounding atmosphere.rnMany opinions, and in some cases misconceptions, exist over what actually is suitable for such an application. Two alternatives are presented here; one using a system approach, the other regarding explosionproof equipment designed for this application.
