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.

Closed Loop Current Sensor

A closed loop current sensor is a high precision device used to measure alternating current and direct current in electrical systems. It is also known as a compensated current sensor because it uses a magnetic feedback principle to improve measurement accuracy and stability. Closed loop current sensors are widely used in industrial automation, renewable energy systems, power supplies, motor drives, electric vehicles, and precision monitoring equipment where reliable current measurement is essential.

4 20ma Current Sensor

A 4 20mA current sensor is an industrial device used to measure electrical current and convert the measured value into a standardized 4 20mA analog output signal. This type of sensor is widely used in automation systems, industrial monitoring, power distribution, renewable energy systems, and process control applications because of its high reliability, long transmission distance, and strong resistance to electrical interference.
