The invention provides a physical experiment table suitable for the electric shock of an animal, and an electric shock impedance modeling method. The platform comprises an experiment power supply, an inductor module and a load, wherein the experiment power supply, the inductor module and the load are connected in series. The inductor module is sequentially connected with a fault recorder and an analysis processing unit. An impedance module is connected between the inductor module and the load. The method comprises the steps: building an animal electric shock physical experiment platform, carrying out the animal electric shock experiment, and obtaining the animal electric shock voltage and current experiment data; obtaining the electric shock information, animal electric shock total impedance, and a phase angle expected value; solving skin resistance and skin capacitance; building an animal electric shock physical experiment platform digital model, and obtaining an animal electric shock impedance final platform. The platform and method can accurately and effectively recognize the animal electric shock information. The platform and method effectively avoid a problem, caused by the reduction of a remaining current, of failure and motion refusal of a remaining current protection device. The platform and method improve the motion reliability and accuracy of the remaining current protection device, thereby improving the guarantee capability for the power supply safety of a rural power grid.
