| description | <p class="Normal1">The use of UHF sensors in high voltage electrical equipment for monitoring its insulation system is widely used. In order to improve these sensors,we present an analysis of different types of dielectric materials that can be used as physical coating and shield, which can enhance the electromagnetic characteristics of UHF microstrip sensors applied to the detection of partial discharges in performance transformers. The materials used as coating were glass, silicone, FR4, Teflon, and acrylic. In order to do so,, HFSS software simulations for the development of analyzes on two UHF microstrip antennas were performed. From the analyzes performed, it was verified the improvement of the reflection coefficient and the gain of the UHF sensor recorded the materials used to demonstrate the practical application. In addition to that, we also had simulations of a typical electromagnetic shield applied in conjunction with the sensor to demonstrate that the shield is still displayed in the design stages and is of great relevance. In order to underpin the data obtained from the simulations, the real models of UHF sensors were applied and tested in the laboratory.</p> |
