520			_aThe results are used as the basis of suggested mathematical equations for the relation tween temperature rise and time A cost / benefit analysis is performed for assessment of the importance of monitoringResults indicate several remarks and conclusionsNo single technique whether on line or off - line , continuous or periodic will cover all failure causesThese techniques for monitoring give a qualitative analysis , not a quantitative analysisOn - line monitoring techniques can provide valuable information regarding the performance of a breakerData analysis performed by qualified personnel is still required in order to determine the action plan resulting from the monitoring resultsThis can be minimized if an expert system is incorporatedMonitoring systems require a careful observation period to ensure the system is setup and responding appropriatelyThe greatest numbers of failures originate in the operating mechanism , so it is the place to start with monitoring
