OpenLeakage current sensors are microcurrent sensors designed for online insulation monitoring of high-voltage electrical equipment.The sensor accurately detects AC current ranging from 100μA to 10A. ProductChosen for its high initial permeability, the core material is paired with a high-precision rectifying circuit and multi-layer metal shielding to compensate for the excitation current of the iron core, enabling it to operate in an ideally zero flux state. The product boasts excellent temperature characteristics and resistance to electromagnetic field interference, allowing for normal operation in strong electromagnetic interference environments.
