Background technique [0002] With the development of the power system, the wire running state detection technology has emerged, that is, to measure important parameters such as current and voltage in the power system to reflect the running state of the power system. In the traditional detection technology of the running status of power conductors, current transformers and voltage transformers are used to measure the current and voltage in the conductors. However, current transformers and voltage transformers are large in size, heavy in weight, and require high installation requirements. Current and voltage transformers are less accurate for measuring current and voltage in wires.

Problems solved by technology

[0003] In recent years, with the advancement of sensor chip-related materials and manufacturing processes, a method of using a single magnetic field sensor to measure the current of a wire has emerged. However, when using a single magnetic field sensor to measure current, it is necessary to know the spatial position relationship between the sensor and the wire in advance. That is, the wire current is calculated from the spatial position relationship and the measured magnetic field strength. Therefore, the installation of the magnetic field sensor is difficult. Once installed, the deviation of the spatial position relationship between the magnetic field sensor and the wire will affect the accuracy of the measurement results, and According to a single magnetic field sensor, the voltage of the wire cannot be obtained, so the detection of the running state of the wire cannot be completed
