MEDIUM-VOLTAGE CIRCUIT BREAKER CONDITION ANALYSIS AND HAZARD AWARENESS

摘要

When performing a condition analysis on medium-voltage circuit breakers located in metal-clad switchgear, it is necessary to be aware of all potential hazards. The person performing the condition analysis must be qualified to perform the task and have a solid understanding of each possible hazard they may encounter and ways to minimize the risks. To better understand the hazards involved with the analysis, testing, and maintenance of medium-voltage breakers, let's look at the sources that contribute to each hazard.
