High-voltage power equipment, due to its complexity, operation under the infl uence of strong electric fi elds, electrodynamic and thermal infl uences, is at high risk of defects, subsequent electrical breakdowns and even complete destruction. Therefore, the problem of improving the operational reliability of such equipment has always been paramount. Maintenance and evaluation of the service life of high-voltage power systems require monitoring the condition of all operating equipment in each specifi c area. The radio frequency method of investigating partial discharges involves the use of electromagnetic sensors to detect and analyze discharges occurring in isolation or vacuum. The radio frequency partial discharge research method is an effective tool for diagnosing the state of insulation in electrical equipment such as transformers, generators, cables and high-voltage equipment. It allows you to identify potentially dangerous discharges that can lead to equipment damage or an emergency situation, and take measures to prevent their occurrence. In this work, laboratory experiments on the diagnosis of high-voltage glass insulators using the radio wave method have been carried out. Electromagnetic radiation was received using a broadband receiver and a special logoperiodic antenna. In order to eliminate electromagnetic interference, the method of synchronous accumulation relative to the phase of the mains voltage was used. The results obtained indicate the effi ciency of the method and the possibility of further development of the device. Keywords: partial discharges, log-periodic antenna, radio frequency method, electric fi eld, high-voltage equipment. DOI: 10.25791/asu.2.2024.1487 Pp. 21-30.
