Based on the principle of Rogowski coil, this paper analyzes its equivalent circuit under differential state. By employing the analytic method of the series of non-period function, it analyzes the spectrum characteristic of three kinds of mathematical models of lightning current According to the spectrum of three types of lightning current, this paper introduces the design method of Rogowski coil based on the system of measuring lightning current, analyzes its characteristic and introduces how to choose the parameters of the coil. This paper summarizes the temperature characteristic of four kinds of materials, and chooses fiber as the framework of the coil. The spectrum characteristic of the coil designed is simulated. It is found that the coil has such virtues as good spectrum characteristic and small distortion, etc.
