摘要：
A simulation model based on FEM (finite element method) is presented to analyze the impulse characteristic of grounding system under lightning stroke while considering soil parameters' frequency dependence. Due to taking the variation of soil frequency-dependence parameters into account, the accuracy of calculation improves. The suggested model is validated by comparing the calculated results with experimental tests and simulations results found in literature.
