Abstract
This paper describes an event in which lightning struck and discharged current into the phase conductor of a 345 kV transmission line. The magnitude of the lightning discharge was insufficient to lead to a flashover (line insulation breakdown). The paper examines and explains the response of two different line current differential protective relays to this event that was inside their zone of protection.
