Research on Lightning Early Warning Method Based on Field Mill Electric Field Meter

The atmospheric electric field instrument is a device for measuring the atmospheric average electric field, which can effectively detect the occurrence and development of lightning by measuring the change of the atmospheric average electric field. The atmospheric electric field detector is mainly divided into field mill type, electronic type and double-ball type. The field mill electric field meter has the best detection accuracy and lightning warning effect. However, compared with other electric field detectors, the field grinding type electric field detector has a higher false alarm rate. To solve this problem, a new type of inductor circuit is proposed, which can effectively eliminate interference signals and ensure measurement accuracy; The effectiveness and practicability of the field mill electric field meter equipped with this kind of inductor are verified by practical operation.
