The present invention relates to an impact sensing device for an electric facility such as a utility pole. The device includes: a housing which is attached to an electric facility and has an inner space; a rotational support bar of which the upper end is supported in a rotatable manner on one point of the housing inside the inner space of the housing and which is extended toward the bottom; a weight pendulum which is combined to the lower end of the rotational support bar and induces the rotation of the rotational support bar by impact or vibration applied to the housing; an impact-linked support bar of which one side is fixed to the inner wall of the housing in a direction crossing over the extension direction of the rotational support bar, of which the other side is combined to the lateral side of the rotational support bar, and which is made of elastic material to be stretched by the rotation of the rotational support bar; a first optical fiber grid which is combined in the extension direction of the impact-linked support bar; a light source; a light circulator which receives the light emitted from the light source, transmits the light to an optical transmission line connected to the first optical fiber grid through a first output terminal, and outputs the light received and reflected from the first optical fiber grid through a second output terminal; a light detection unit which detects the light outputted through the second output terminal of the light circulator; and an impact measuring unit which measures whether an impact is applied to the electric facility where the housing is installed from the light detected by the light detection unit. According to the impact sensing device for an electric facility, by installing multiple impact sensing devices onto an electric facility such as a utility pole, it is possible to monitor the safety status of the electric facility at a remote place by receiving the impact information on whether an impact is applied to the electric facility through a communication network.
