Abstract The ground wire of high voltage overhead line commonly composes a common overhead ground wire and an OPGW. The induced voltage and current of four grounding modes of a typical 750kV transmission line are calculated by ATP. It is shown that the induced current is largest when ground wire is grounded at each tower. When segment-insulated grounding at one tower is adopted, the longer the segment length is, the larger the induced voltage is. The results provide a basis for selection and improvement of OPGW grounding mode.
