Description

technical field [0001] The invention relates to the technical field of power system equipment, in particular to a capacitive transformer with a voltage monitoring system; the invention also relates to a voltage monitoring method for a capacitor transformer with a voltage monitoring system. Background technique [0002] At present, the voltage transformers used in the AC high-voltage power system with a voltage level of 110KV and above are divided into two types. One is an electromagnetic voltage transformer, which is easy to excite ferromagnetic resonance, and has poor reliability and high cost during operation; the other is a capacitive voltage transformer, whose working principle is to reflect the high voltage through the tap voltage value of a capacitor voltage divider. The voltage value at the terminal; the tap is connected to the electromagnetic device, and the electromagnetic device is composed of an intermediate transformer, a compensation reactor and a ferromagnetic ...
