Performing Temperature Regulation and Monitoring in an Oil Aging Test System

We developed a system that continuously monitors, logs, and regulates transformer oil temperature during the aging process and maintains temperature consistency within strict limits. A microcontroller system was developed using two PWM regulation algorithms for controlling oil temperature set value in the range of 40C to 200C. An oil temperature monitoring and measured data logging system based on National Instruments cRIO technology was also developed to observe 12 transformer oil samples simultaneously within the fixed time period. The measured temperature values are stored in a database for further analysis.
