Abstract

Maintenance monitoring may be provided. First, a plurality of status data respectively corresponding to a plurality of components on a power line may be collected. Then the collected plurality of status data may be analyzed to determine when a one of the collected plurality of status data is outside of a normal operation range for a one of the plurality of components corresponding to the one of the collected plurality of status data. Next, results of the collected data analysis may be displayed. The results may indicate that the one of the collected plurality of status data is outside of the normal operation range for the one of the plurality of components corresponding to the one of the collected plurality of status data.
