The leakage current sensor is a novel current sensor that is based on the magnetic modulation principle. It compensates for the primary current using the current generated by its internal oscillator, achieving magnetic field balance. As a result, the secondary voltage accurately reflects the primary current. It offers stable low current measurement performance, superior precision, good linearity, a wide measurement range, strong overload capacity, a perforated structure, and no insertion loss. Leakage current sensors are widely used for real-time monitoring of the insulation status of busbars and branches in DC and AC power supply systems, helping to promptly identify and address potential electrical faults. Additionally, they play a significant role in household electrical safety monitoring, industrial leakage fault monitoring, and electrical equipment leakage fault monitoring across all sectors of the power industry, capable of promptly detecting and sending alarm signals to prevent losses due to electrical accidents.
