Patent number: 11435409Abstract: A detection scheme for temporary overvoltages and/or ground fault overvoltages in electric power systems is described. Current passing through a surge arrestor component of the power system is monitored. An algorithm for identifying one or more frequency components of the measured current signal is performed to screen out unwanted harmonics. In some embodiments, this is a frequency domain analysis. The frequency component(s) of the current signal is then compared to a calculated pickup current or pickup voltage of the system to determine if system protection steps should be undertaken.Type: GrantFiled: January 9, 2019Date of Patent: September 6, 2022Assignee: Rensselaer Polytechnic InstituteInventor: Huan Guo
