Earth Leakage Sensing Description
Earth Leakage Sensing is an important electrical safety function used to detect unwanted current flowing from an electrical circuit to earth. Earth Leakage Sensing Current Transformers (CTs) provide a reliable method of monitoring residual current and identifying leakage conditions before they can lead to equipment damage, electrical hazards, or system downtime. These sensing transformers are designed to provide accurate and sensitive detection for modern protection and monitoring systems.
By continuously monitoring the balance of current flowing through a circuit, an earth leakage sensing CT can detect residual current caused by insulation deterioration, wiring faults, or other leakage conditions. The resulting signal can be used by protection and control equipment to trigger an alarm or protective action.
At Shah Electronics, Earth Leakage Sensing CTs are engineered using quality magnetic materials and precision manufacturing processes to deliver high sensitivity, consistent performance, and reliable operation. They are suitable for industrial power systems, electrical distribution equipment, EV charging stations, solar inverters, UPS systems, battery energy storage, control panels, and power electronic equipment. These magnetic sensing solutions help improve electrical safety, support preventive maintenance, and enable reliable leakage current monitoring in modern electrical installations.
