Blue Arc identifies specific areas and circuits where trimming wasn’t effectively reducing outages and implements improved approach.
Maintenance Effectiveness Study
Situation: A utility maintenance manager suspects that tree-trimming maintenance practices are ineffective in some areas and that customers on specific circuits are experiencing recurring power interruptions due to tree-related outages.
Action: Blue Arc gathers and organizes maintenance and failure data to measure the time between routine tree-trimming maintenance and customers' power failures. Maintenance effectiveness is quantified with decreasing effectiveness over time. Non-maintenance related failures, such as those caused by broken limbs, are established as random failures.
Benefit: The utility successfully identifies the specific areas and circuits where trimming maintenance practices are ineffective due to circuit overhead hazards and vegetation density. Affected customers are offered alternative maintenance approaches to increase reliability and customer satisfaction.
