MAINTENANCE Page 21 VACUUM CHECK A sufficient level of vacuum is necessary for proper performance of the vacu um interrupters. Although vacuu m leaks are rare, the vacuu m integrity should b e checked periodically. The relationship bet ween dielectric breakdown voltage of the con tact gap and i nternal vacuu m interrupter pressure has been found to[...]

Page 22 MAINTENANCE CRITERIA: 1. If a current flow above 5 milli-amperes is observed or if breakdown occurs, one or more of the inte rrupters has ins ufficient vacuum and must be replac ed. Exception: If the current exceeds 5 milli- amperes the first time the voltag e is brought up, reduce the voltage to zero and i ncrease it again. It may be nece [...]

MAINTENANCE Page 23 ELECTRICAL SERVICE LIFE The electrical service life of the vacuum interrupter is defined by the electrode wear and the number of open/close operations (mechanical life). To determine electrode wear, measure the distance between the lever and washer in the closed (ON) state, as shown in Figure 13. This dimension is called the “[...]
