Cable Sheath Ground Current Monitor

Product description The metal sheath of the high-voltage cable is an important part of the cable. When the cable core passes current, a circulating current will be generated on the metal sheath. The poor insulation state of the outer sheath, poor grounding, and incorrect grounding of the metal sheath will all cause The sheath circulation is abnormal, which will threaten the safety of cable operation in severe cases. When the circulating current of the metal sheath of the cable is abnormal, it will cause the local high temperature loss and heat generation of the cable insulation, which will accelerate the aging of the insulation, reduce the service life of the cable, and cause direct breakdown and grounding faults of the cable in severe cases. Abnormal sheath circulation will also directly affect the current carrying capacity of the cable line, resulting in a large power loss, wasting power and reducing economic benefits.

The metal sheath of the high-voltage cable is an important part of the cable. When the cable core passes current, a circulating current will be generated on the metal sheath. The poor insulation state of the outer sheath, poor grounding, and incorrect grounding of the metal sheath will all cause The sheath circulation is abnormal, which will threaten the safety of cable operation in severe cases. When the circulating current of the metal sheath of the cable is abnormal, it will cause the local high temperature loss and heat generation of the cable insulation, which will accelerate the aging of the insulation, reduce the service life of the cable, and cause direct breakdown and grounding faults of the cable in severe cases. Abnormal sheath circulation will also directly affect the current carrying capacity of the cable line, resulting in a large power loss, wasting power and reducing economic benefits.

The WINFOSS-W7 sheath grounding current monitor is a monitoring product designed by Weavers for the safety of high-voltage cables in the power pipe gallery in the integrated pipe gallery in the underground space. With 4 current monitoring channels and 3 temperature measurement channels, it can realize real-time automatic monitoring of sheath grounding current data, display the monitoring data intuitively in the form of graphs, and provide early warning and alarm through data analysis, so as to effectively prevent power cables. The occurrence of accidents, prolong the service life of power cables, ensure the safe and stable operation of power cables, reduce manual workload, and save operation and management costs.
