Abstract:
Insulator is an important device to separate between conductors of the electric power systems transmission. Generally, insulator is affected by environmental conditions such as temperature, humidity and other pollutants. Therefore, it is necessary to test the insulator in a simulated environment using a controlled chamber to determine the characteristics of the insulator leakage current. In this paper, a PID controller was implemented to control the chamber temperature. The PID controller is embedded in the Arduino R3 microcontroller which is connected to a DHT22 sensor and a thermoelectric cooling actuator (TEC12706.) Experimental results show that the PID controller can maintain the chamber temperature at the desired setpoint with Kp = 200, Ki = 10, Kd = 5. The system can reduce the temperature up to 23.6 °C with a rise time of 198 seconds with a peak time of 218 seconds at a temperature of 24.8 °C. The system can reach a preset temperature value with a response time of 32 seconds.
