Temperature logger for Electrical Equipment's Thermal Stress Monitoring

摘要

This paper aims to present the importance of the electrical equipment's temperature monitoring by highlighting how its thermal stresses can indicate a malfunction of equipment. When defective electrical equipment or improper electric loading or damaged metallic or non-metallic components occur, they are usually due to abnormal temperature models. Also the paper presents the development and manufacturing of a temperature logger that can successfully monitor the thermal stress of electrical equipment in multiple independent points. In addition, the paper shows how the thermal stress of a busbar connection are monitored by the temperature logger. By the laboratory experiment is intended to exemplify how important is to have enough number of temperature monitoring points of the electrical equipment's constructive elements.
