METHODS FOR ASSESING THE TECHNICAL CONDITION OF SUBSTATION ELECTRICAL EQUIPMENT BASED ON THE INFLUENCE OF THERMAL FACTORS
Abstract
This article considers a diagnostic approach based on thermal factors and temperature criteria for assessing the technical condition of substation electrical equipment. The normal and faulty heating states that occur during the operation of electrical equipment are physically analyzed and their relationship with the load current is studied. The role of temperature as an indicator of technical condition is substantiated, and the possibility of a quick and reliable assessment of the condition of the equipment using the relative temperature indicator is shown. Based on graphical and tabular analysis, criteria for determining normal operating conditions, contact defects, and pre-accident conditions are proposed. The results obtained are of practical importance in improving condition-based technical maintenance systems for electrical equipment.
