Resumen

Partial discharge detection has been a challenge for electrical power systems and industrial automation; However, in recent years, with the evaluation of the state of non-intrusive electrical components and the detection of parasitic currents and high-frequency partial discharge, new mathematical developments and control systems for early detection have been allowed. In the present investigation, a sensor with 10 Rogowski coils is proposed; Mach - Machined, RSC - Rigid Split Core, RFC - Rigid Fixed Core, PCB, FCO - Openable Flex Core, FCF - Fixed Flex Core. Our findings are an accuracy for the partial discharge detection is 92.8% for voltage 220V for 10 A to 250A; during a time of 30 minutes; and an accuracy for the partial discharge detection is 81.2% for voltage 220V for 251 A to 350A; during a time of 30 minutes with comparison with effect Hall sensors and the disadvantage.
