Abstract

This paper presents a criterion and priority of electrical maintenance based on fuzzy system. Thermal

imager is one of equipment in electrical engineering field that is used for electrical system inspection and

maintenance. Normally. hotspots that are inspected by a thermographer are analyzed based on a

conventional criterion, which only referred temperature rise. The temperature rise is a different of temperature

between actual temperature of a hotspot and reference temperature. As the conventional criterion is not able

to indicate and represent a degree of equipment damage completely. This paper Introduces the alternative

methodology of decision making for electrical maintenance planning. The paper not only considers the

temperature rise but also included other factors such as a percent of load operating and a degree of critical

equipment The three factors are applied to an input of the fuzzy system and the rule based of the fuzzy

system is advised and created by an electrical engineer which they have an experience in electrical

Inspection by thermal imager. The output of the fuzzy system is the criterion and priority of electrical

maintenance based on fuzzy system As the result. the criterion and priority of electrical maintenance based

on fuzzy system is able to indicate a degree of equipment damage better than the conventional criterion (the

temperature rise based) The benefit of this paper describes the alternative methodology :o define a suitable

priority for electrical maintenance planning. If inspectors have a suitable criterion of electrical maintenance. the operation cost, maintenance cost and an outage time will be reduced automatically
