Abstract: A vehicle-to-everything (V2X) communication-based electronic toll collection system (ETCS) according to an embodiment of the present invention includes at least one roadside unit (RSU), a token issuer checking a de-identified token of a vehicle by communicating with an on-board unit (OBU) of the vehicle via the at least one roadside unit, and a clearing house communicating with the token issuer and charging a toll to a driver/owner of the vehicle. The token issuer generates toll information of the vehicle based on the de-identified token of the vehicle and location information of the at least one roadside unit involved in checking the de-identified token.

Abstract: A ground type elbow connector includes an elbow housing 100, and an electroscope 200 that is assembled onto the elbow housing to allow both a visual check on an activated state of a power cable and a grounding operation to occur. The elbow housing is connected to an insulation plug of an elbow connection unit for a power cable that is assembled onto a voltage detection part opposite to a bushing coupling part via which the elbow connection unit is connected with a bushing insert of a switch.

Abstract: A grounding type elbow connector includes an insulation plug having an electrically-conductive stud bolt, an insulation body, and an insulation rod that is detachably fitted into a through-hole of the insulation body. A grounding unit having a grounding rod and to which a grounding cable is connected is connected alone, or selectively coupled in a state a grounding inspection connection unit is connected, to the elbow connector after the insulation body is dissembled from the elbow connector.
