【Abstract】 A new optical fiber measuring system for alternating current and pulse cur- rent is proposed.This system can measure large currents from kiloamperes to megaamperes and posseses many adventages:(1)its structure is simple,(2)its measuring range is extensive,(3)its responsive velocity is fact,(4)its isolated intension is high ,(5)it is convenient to link with computer,(6)it has few influence of electromagnetic interference and saturation,which are inherent in traditional measurement methods.Principle and construc- tion of this system are presented in this paper.更多还原
