At this stage, with the continuous improvement of the substation voltage level and the use of related intelligent equipment, the electromagnetic environment is gradually complicated, which seriously threatens the safety and reliability of the operation of the high-voltage transmission system.In view of this, based on the analysis of the theory of substation ground potential difference, this paper studies the specific causes of electromagnetic interference of shielded cables in substation ground potential difference, and then proposes the main measures to prevent the rise of substation ground potential, and the anti-interference ability of shielded cables. It is of great practical significance to improve the anti-jamming ability of shielded cable.
