Abstract
In power systems, corona discharge often occurs, which is a common phenomenon. If it occurs in electrical equipment, then hidden dangersexist, such as poor contact between metal fittings of insulators and electrical equipment, insulation performance degradation due to equipment agingand strand breakage of transmission lines. These dangers may lead to further serious accidents. So, it is very important to detect and eliminate the hidden dangers. Because corona discharge will radiate radio frequency (RF) electromagnetic waves to the surrounding space, the detection of corona discharge can be realized by detecting RF electromagnetic waves. In this study, two miniaturized antennasare designed to detect corona discharge in electrical equipment. These antennasare rectangular spiral antennaand Hilbert antenna. Through simulation and comparison, it is found that Hilbert antenna unit is the best and the final structure is the 6 order Hilbert antenna. The final size of this antenna is 100 mm*100 mm*1.6 mm, which is portable and lightweight.
