Abstract

In the history of surgical procedure, patients have the possibility to bare the side effect of the electrical shock. This electric shock is caused theoretically by electromedical equipment within the medical room surrounding. A primary concern of this electric shock is when there is a micro-shock that passed through the patient while having medical operation and can harm the patient. However, a problem rises when the detection of the leakage current is not accurate. The objective of this project is to design and develop an insulation monitoring device for detecting the leakage of current in IT electrical network system. The second objective of this project is to test the performance of proposed system in terms of accuracy and precision. For the methodology, the proposed system will be using Arduino UNO and voltage divider theory. Data for this study will be collected using two methods which are from simulation setup and experimental setup. For simulation setup, software Proteus Release 8.0 is used. By employing experimental setup, a circuit contains a decade resistor and a socket for the 100-W lamp to replicate the medical room situation is built. From the experimental setup, the accuracy, precision and sensitivity can be obtained. The finding of the experiment is that the insulation - monitoring device able to detect the leakage of current even though there are error on current measurement from the electrical network system. The average percentage error for accuracy is at 15.683% and the average percentage error for the precision is at 14.59%. On top of that, the sensitivity of the IMD detection is at 37.74%. Thus, for recommendation to increase the reliability of the device, more powerful microprocessor need to be implemented to reduce the error.
