Leakage Current Sensor: Indispensable Detector for Electrical System Safety

A leakage current sensor ​is a high-precision measuring component specially designed to track residual leakage current inside power circuits, acting as the first line of defence against electric shock and electrical fire hazards in modern power distribution, new energy and industrial control systems. Ordinary current transformers only measure load current, yet this sensor focuses on tiny stray currents escaping from damaged insulation, aging cables, faulty wiring or incomplete equipment grounding, which pose hidden safety risks hard to spot via regular monitoring tools. It converts faint leakage signals into readable electrical outputs to support real-time monitoring, threshold alarming and power interlock protection.

Hall Effect Current Sensors

First discovered by physicist Edwin Hall in 1879, Hall effect current sensors have become the dominant isolated current measurement component across power electronics, automotive and industrial equipment, solving critical limitations of traditional shunt resistors and current transformers. Based on the Hall effect principle, when charged carriers inside a semiconductor plate pass through a perpendicular magnetic field, a measurable transverse voltage (Hall voltage) forms. Since the magnetic flux surrounding a conductor is linearly proportional to its carried current per Ampere’s law, the Hall voltage can be converted into an accurate signal representing current magnitude, achieving fully galvanic isolation between high-voltage primary circuits and low-voltage control circuits.

DC Current Sensors

DC current sensors are devices designed to measure and monitor direct current (DC) flowing through an electrical conductor without interrupting the circuit. They play an important role in modern power electronics, renewable energy systems, electric vehicles, battery management systems, and industrial automation. As DC applications continue to expand, the demand for accurate, stable, and efficient current sensing technologies has significantly increased.

Hall Current Sensor VS Eddy Current Sensor

​Current sensing technologies play a critical role in modern industrial automation, power monitoring, renewable energy systems, electric vehicles, and electronic equipment. Among the many available technologies, eddy current sensors and Hall current sensors are widely used for non-contact measurement applications. Although both technologies can detect electrical or magnetic changes without direct electrical contact, they operate based on different principles and are designed for different measurement tasks.
