The lightning arrester is connected between the cable and the earth, usually in parallel with the protected equipment. The lightning arrester can effectively protect communication equipment. Once abnormal voltage occurs, the lightning arrester will act to protect. When the communication cable or equipment is operating under normal working voltage, the arrester will not work and will be regarded as open circuit to the ground.

Due to electromagnetic induction, the metal shielding layer (or metal sheath) of long line high-voltage single core power cables generates induced voltage, which leads to aging of insulation and reduction of insulation grade, resulting in reduced cable life. Once the induced voltage exceeds the sheath breakdown voltage, the outer sheath is broken down, forming a multi-point grounding fault of single core cables.
