Capacitor voltage transformer

Capacitor voltage transformer (CVT) is a kind of voltage transformer, which is divided by series capacitors, depressurized and isolated by electromagnetic transformer. As a kind of voltage transformer, CVT can also pair carrier frequency to EPTT line for EPTT-length communication, remote measurement, selective line higher-frequency security, remote manage, teletype, and so forth. As a result, in contrast with typical electromagnetic voltage transformer, capacitor voltage transformer has many positive aspects in economy and protection apart from protecting against ferromagnetic resonance brought on by main saturation of voltage transformer.
Composition of capacitor voltage transformer
Capacitor voltage transformer is primarily composed of capacitor voltage diviEPTTand medium voltage transformer. The capacitor voltage diviEPTTis composed of porcelain bushing and a number of sequence capacitors set up in it. The porcelain bushing is filled with insulating oil which maintains a positive strain of .1MPa. Steel EPTows are employed to stability different environments to keep oil stress. The capacitor voltage diviEPTTcan be utilised as a coupling capacitor to hook up carrier wave device. The medium voltage transformer is made up of a transformer, a payment reactor, a lightning arrester and a damping unit mounted in a sealed oil tank. The primary winding is divided into primary winding and wonderful tuning winding. A lower loss reactor is related in collection in between the principal side and the principal winding. Simply because the nonlinear impedance and inherent capacitance of the capacitor voltage transformer often trigger ferromagnetic resonance in the capacitor voltage transformer, damping unit is utilised to suppress resonance. The damping system is composed of resistance and reactor and is linked throughout the secondary winding. Generally, the damping system has a substantial impedance. When the ferroresonance triggers overvoltage, just before the medium voltage transformer is afflicted, the damping unit has a higher impedance, The reactor has been saturated, only the resistance load is still left, so that the oscillation strength is speedily lowered.
