Research on several LEMP electric field measuring equipment´s emendation devices

In order to guarantee lightning electric Held measuring equipment´s veracity and relativity, electric field measuring equipment must be emendated before using. In this paper, analysised of the performance of bounded wave simulator, parallel plate electric field generator and homemade U-type emendation device when they were used to emendate lightning electric field measuring equipment. Analysised of electric field´s uniformity in the bounded wave simulator´s space under the lightning wave electric field excitation by Finite-Difference Time-Domain Method, and proved parallel plate electric field generator and U-type emendation device can emendate lightning electric field measuring equipment through test.
