Abstract:This thesis gathered information from several papers in the field of electromagnetic interference and Power Quality. Electromagnetic interference (EMI) and power quality issues can damage equipment and with large medical equipment, failure can be dangerous and costly. A Power Quality Monitor was then tested for accuracy and ability to record EMI events before being placed at the University of Twente’s Techmed building. This building contains many large medical equipment such as X-rays, CT Scanners, and MRI machines. Two of these devices were placed in the proximity of the MRI, however in different areas. The goal was to collect data and observe if EMI events or MRI scans could be seen by analyzing the voltage RMS data collected. This is important as an increasing number of electrical devices are being added to the grid especially ones that have sensitive and non-linear components. With the data that was collected no EMI events were detected and it was not possible to predict when an MRI scan was conducted using the voltage RMS data. This is likely due to limitations that the Power Quality Monitor has and potentially due to the building having a strong grid.
