Survey Says! Maintenance Is Critical As Part Of Your Electrical Safety Program

05/15/2011
When 10.5 percent of electrical equipment doesn’t operate, it is not hard to understand why it is widely touted that electrical maintenance of power distribution equipment is paramount to worker safety. This includes the correct operation of virtually any device such as relaying protection, fuses, and circuit breakers that are required to operate during a fault condition. These devices are required to operate according to their time-current characteristic curves to ensure that a calculated arc-flash hazard analysis is valid. Even a slight variation between theoretical and actual operating characteristics can mean a drastic change in incident energy levels.
