Design Of Temperature And Humidity Control Devices In The Leakage Current Test Chamber Of 20 kV Insulator

Measurement of the Leakage Current in a Test Chamber needs to be done to find out the durability characteristics of 20kV insulator against high-voltage. Durability of insulating material especially 20 kV insulator was heavily influenced by the state of the environment, particularly the temperature and humidity are very diverse, therefore to obtain accurate test results required a test chamber with temperature and humidity similar to State of the environment. However, the currently test chamber that often used for testing of insulating material does not have temperature and humidity controller so that the test results of electrical materials are not accurate. In this paper, a 20 kV isolator leakage current test chamber is designed with a temperature and humidity regulator applies an on-off control method implanted in Arduino Uno Rev.3 that can condition the test chamber to resemble environmental conditions to obtain accurate test results. In this paper the temperature setting is carried out at three set points namely a maximum temperature of 33 ° C with a minimum humidity of 58%, an average temperature of 27 ° C with an average humidity of 82% and a minimum temperature of 21 ° C with a maximum humidity of 91%. The measurement results show that the maximum temperature setting with minimum humidity obtained the highest temperature measurement results of 33.30 ° C and the lowest humidity of 58.25%. In the average temperature setting with average humidity, the measurement results obtained near the set point, namely the temperature of 27.25 ° C with a humidity of 81.60%. While the minimum temperature setting with maximum humidity obtained the measurement results closest to the set point that is the temperature of 25.35 ° C with a humidity of 91.50%
