互感器又稱為儀用變壓器，是電流互感器和電壓互感器的統稱。能將高電壓變成低電壓、大電流變成小電流，用于量測或保護系統。其功能主要是將高電壓或大電流按比例變換成標準低電壓（100V）或標準小電流（5A或1A，均指額定值），以便實現測量儀表、保護設備及自動控制設備的標準化、小型化。同時互感器還可用來隔開高電壓系統，以保證人身和設備的安全。
在供電用電的線路中，電流相差從幾安到幾萬安，電壓相差從幾伏到幾百萬伏。線路中電流電壓都比較高，如直接測量是非常危險的。為便于二次儀表測量需要轉換為比較統一的電流電壓，使用互感器起到變流變壓和電氣隔離的作用。
 顯示儀表大部分是指針式的電流電壓表，所以電流互感器的二次電流大多數是安培級的（如5等）。隨著時代發展，電量測量大多已經達到數字化，而計算機的采樣的信號一般為毫安級（0-5V、4-20mA等）。微型電流互感器二次電流為毫安級，主要起大互感器與采樣之間的橋梁作用。微型電流互感器稱之為“儀用電流互感器”。（“儀用電流互感器”有一層含義是在實驗室使用的多電流比精密電流互感器，一般用于擴大儀表量程。）
