The operation of a complete power system may depend entirely upon the reliable operation of the breakers under any emergency. When a short circuit occurs on a power line, the portion in which the disturbance originated must be isolated quickly to prevent damage to associated apparatus and to restore service to the rest of the system. Its entire operation must be completed in less than one tenth of a second. To obtain this high‐speed operation, friction in moving parts must be reduced to a minimum and therefore correct lubricants for power circuit breakers are very important.
