Determination of Weighting Factor for High Voltage Equipment Replacement Priority Index using Analytic Hierarchy Process

PLN has regulations for equipment replacement but it should be improved to determine the criticality and priority level of equipment to be replaced. The large amount of equipment meets the replacement criteria has to be prioritized based on risk and impact. In the previous studies, there were discussions in terms of the Analytical Hierarchy Process method to determine the weighting of the parameters that make up the Health Index of the equipment. However, to determine the priority for High Voltage equipment replacement should consider the Risk parameters and Asset Health Index which including Condition Assessment Factor and Performance Assessment Factor. Additionally, the hierarchical model was formed by getting advices from 30 experts which were given a survey to get the weighting of each parameter. These experts have previously been examined in terms of their knowledge and experience, so dependable results can be obtained. The priority for replacing equipment from this research has been running from 2020 to 2022 and had the impact in reducing the number of interruptions and breakdown of equipment.
