Abstract: The electricity combined environment test in earthquake band could analog the real outburst working condition of equipment, which could be used to check the security and reliability, verify the equipment design and find the possible problems and defects in special working condition. Based on certain large-scale earthquake bedstand, this paper established the simulation model of paradoxical discharge in electricity combined environment test of earthquake band for ±11 00 kV direct current potential transformer. This paper analyzed the peak and frequency spectrum of discharge current, researched on the impacts of different capacitance test object on the discharge current peak and gave the anti-jamming measures and suggestions of seismostation measurement and control system.
Key words: earthquake test; distribution parameter; discharge current; electromagnetic interference
