Abstract
A method and detector for monitoring electrical strikes along a power transmission distribution system are described. The method and detector identify the location within the transmission system where an insulator flashover event has occurred. The method includes sensing the magnetic field about the live transmission line(s) upstream and downstream from each transmission tower and providing signals representative of the upstream and downstream magnetic fields. These signals are then compared and a flashover event signal is provided whenever the signals representative of the magnetic fields differ about a tower. The event signal identifies the tower within the system on which the insulator flashover occurred. A detector corresponding to the method is also provided.
