Why Sheath Current Monitoring in Power Cables
Sheath currents in power cables are caused by induced voltages, capacitive coupling, and the electrical current that flows through the metallic sheath of a cable. These sheath currents depend on the asymmetry of the load currents, laying methods and electromagnetic fields. If not monitored, these currents can result in additional energy losses, cable ampacity reduction, overheating, and even safety risks like electric shocks.
Abnormal levels of sheath currents can indicate severe conditions such as degradation of insulation, ground faults, or external electromagnetic interference, issues leading to cable failure and unscheduled outages. For cables, these currents induce long-term imbalance and stress in the network.
Traditional monitoring methods often fail to detect minor variations or incipient anomalies. Continuous sheath current monitoring overcomes this limitation. It enables early fault detection and greatly enhances cable safety when combined with proactive maintenance strategies.
Why Rugged Monitoring-
Rugged Monitoring’s sheath current monitoring in power cables provides real-time solutions to enhance predictive maintenance and extend cable lifespan. Our solution offers smart IoT sensors, edge devices, and APM software to monitor sheath currents continuously, capturing early indicators of wear, insulation failure, and electromagnetic interference before they develop into catastrophic failures.
Our solutions minimize safety threats and preclude unscheduled outages by identifying current imbalances due to load asymmetry, cable construction, or external influence. With real-time remote monitoring and AI-driven analysis, our RM EYE solution offers complete health indices across multi-cable systems and supports experts enabling data-driven decision-making.
Designed for seamless integration with SCADA and APM platforms, our solution accommodates offline, periodic, and online monitoring strategies. With field-configurable alarms, intuitive dashboards, and predictive diagnostics, Rugged Monitoring makes condition-based maintenance easy. It helps lower operating expenses, improve grid reliability, and maximize long-term asset performance and ROI.
