摘要（英）：

The invention discloses a device and a method for detecting three-dimensional space electromagnetic field distribution of a hydraulic power plant. The device comprises an electromagnetic field antenna-probe, a conditioning circuit, a microprocessor and a man-machine interface module which are sequentially connected, wherein the electromagnetic field antenna-probe comprises a three-dimensional magnetic field induction antenna and a three-dimensional electric field measuring probe; the conditioning circuit is a dual-channel signal processing circuit which is used for respectively processing signals outputted by the three-dimensional magnetic field induction antenna and signals outputted by the three-dimensional electric field measuring probe, and each channel of the signal processing circuit comprises a forestage isolation circuit and a filtering and amplification circuit; and the microprocessor or the conditioning circuit is integrated with an A/D converter which carries out analog-to-digital conversion on signals outputted by the filtering and amplification circuit. The device and the method for detecting three-dimensional space electromagnetic field distribution of the hydraulic power plant are easy to implement, and can accurately detect three-dimensional space electromagnetic field distribution conditions of the hydraulic power plant.
