Development Status of High Voltage Insulation Technology Using VIKOR Method A Multi-Criteria Decision-Making Approach for Performance Evaluation Insulating high voltage electrical equipment involves various aspects such as the advancement of structural designs, the selection of appropriate materials, designing processes, manufacturing techniques, operational protocols, and maintenance procedures. These technologies are crucial for ensuring the safe and efficient operation of electrical appliances that utilize conductors at varying potentials. The insulation structures play a vital role in separating these conductors, thereby emphasizing the significance of backup systems in electrical appliances. Ensuring environmental sustainability in traditional cross-linked polyethylene (XLPE) insulation poses a challenge in meeting the demands of sustainable development. The ultimate phase of the self-repairing mechanism involves the polymerization of monomers, catalyzed by epoxy resin upon contact. This process resembles the electrical breakdown caused by electric trees, often paralleled by mechanical cracking in the material. The effects of these advancements and potential future paths for novel backup systems are deliberated upon in each context. Available from various manufacturers, these systems offer an additional layer of compression through streamlined and integrated technologies. They present an opportunity to enhance the resilience of power plants, particularly in managing surges, as they can be implemented throughout the entire substation, ensuring comprehensive overvoltage control. The voltage applied exhibits variability based on temperature fluctuations. This phenomenon affects conductivity and the accumulation of space charge. The impact of a random electric field generated by this distribution is briefly addressed. Within our expanded VIKOR model, which encompasses various decision criteria, we utilize the Analytic Hierarchy Process (AHP) method to determine weights through fuzzy analysis. The aim of this thesis is to enhance the understanding and application of the Dynamic Intuition is Fuzzy Multi-Attribute VIKOR (DIF-MADM) Method. This involves clarifying the concept and methodology, particularly focusing on integrating the PFNP model and VIKOR method into a cohesive framework. The thesis seeks to develop a fuzzy normalized schema for the VIKOR method, thereby contributing to its expansion and clarity. It will also review the current state of VIKOR applications, classify and analyze existing research, and provide a comprehensive explanation of the topic through a modern literature review. The text implies that the discussion extends to additional aspects of VIKOR. With the introduction of new measures, the text suggests confidently employing the fuzzy VIKOR method. It proposes a method for multi-criteria decision-making that incorporates optional information, expressing assurance in its effectiveness. To demonstrate its utility, a practical example is provided. Solid Insulation Materials is got the first rank whereas is the Gas Insulated Switchgear (GIS) is having the Lowest rank.
