電容式電壓互感器（CVT）是由串聯(lián)電容器分壓，再經(jīng)電磁式互感器降壓和隔離，作為表計、繼電保護等的一種電壓互感器，電容式電壓互感器還可以將載波頻率耦合到輸電線(xiàn)用于長(cháng)途通信、遠方測量、選擇性的線(xiàn)路高頻保護、遙控、電傳打字等。因此和常規的電磁式電壓互感器相比，電容式電壓互感器器除可防止因電壓互感器鐵芯飽和引起鐵磁諧振外，在經(jīng)濟和安全上還有很多優(yōu)越之處。

Capacitive voltage transformer (CVT) is composed of series capacitor voltage, then through electromagnetic transformer step-down and isolation, as the meter, relay protection, such as a voltage transformer, capacitor voltage transformer can also be coupled to the power line carrier frequency used in long distance communication, distance measurement, selective circuit high frequency protection, remote control, teletype, etc. So compared with the conventional electromagnetic voltage transformer, capacitor voltage transformer device in addition to can prevent the ferromagnetic resonance caused by voltage transformer iron core saturation, on economic and security and is superior in many places.
