Abstract In this paper, the surface electric field distribution of two kinds of 330kV organic composite insulator and the voltage distribution of toughened glass insulator string were actual measured in the testing laboratory. Through the establishment of test platform, surface contamination layer of insulator was built by artificial contamination method. The voltage distribution on surface of insulator under clean and dry and uniform pollution layer condition were obtained. Comparison with theoretical simulation results in previous word was taken. The accuracy of the simulation calculation was verified.
