Predictive Maintenance - The Key to Power Quality

When PQ problems become apparent – usually in the form of a disruption – they are usually referred to as ‘events’. This terminology is misleading because it hides the fact that the causes of many ‘event’ could have been identified in advance by the use of predictive maintenance techniques. This Application Note proposes that, rather than simply responding to problems, PQ should be continuously monitored as part of a planned maintenance activity.
