Evidence of Need for Improved Coordination and Protection of Industrial Power Systems

This paper was developed to introduce the showing of slides depicting damage to industrial distribution apparatus from sustained arcing and fire. The pictures selected from accident case histories should serve as evidence of the need for improved coordination and protection of industrial power systems. A systematic periodic maintenance practice is suggested and strongly encouraged to detect impending trouble before faults occur. This is a rewarding investment towards assuring continued reliable and profitable productive operation. While this undoubtedly will reduce the frequency of trouble, faults do occur from any one of a number of unforeseeable reasons in the best of installations. Proper coordination and adequate protection can mean the difference between a minor accident or a catastrophe.
