電量變送器的原理電量變送器是一種將被測電量(交流電壓、電流、有功功率、無功功率、有功電能、無功電能、頻率、相位、功率因數(shù)、直流電壓、電流等)轉(zhuǎn)換成按線性比例直流電流或電壓輸出(電能脈沖輸出)的測量儀表。它很多應(yīng)用于電力、石油、煤炭、冶金、鐵道、市政等部門的電氣測量、自動控制以及調(diào)度系統(tǒng)。電量變送器的基本測量電路一般由下圖幾個部分組成：由于我們需要測量的電量一般都為高電壓(57.7-380V)和大電流(1A-10A)，如果不對它們進行隔離和把幅度減小，將對人身安全和設(shè)備造成嚴重威脅，信號輸入隔離一般采用電壓互感器(PT)和電流互感器(CT)。
