Test and verification of electric field characteristics in seawater based on ship scaled model

The test and verification of the electric field characteristics of the scaled model is to make a certain scale model by scaling the size and electrical parameters of the ship through the electric field similarity criterion, and the electric field characteristics of the scaled model are measured under controllable conditions through experiments, and the test results are compared with the simulation results to verify the effectiveness of the test. At present, the characteristics test and analysis of scalar potential or single vector electric field in water based on the scaled model have been carried out in China, but the research on using vector array to obtain three-component electric field data is still in preliminary development, and it is difficult to obtain its spatial characteristics at the same time, resulting in unscientific test methods and incomplete characteristic parameters. In this paper, the model is fixed on the vehicle, multiple sensors are fixed and arranged according to a certain distance to form a measurement array, and the scaled model moves in the direction of the vertical measurement array to obtain the electric field value of the model in a certain plane range at the measurement depth through the sensor array in the water, which can obtain more comprehensive and systematic spatial distribution characteristics than other test methods.
