Abstract
A kind of online insulation and error monitoring technique had been introduced in this paper and this kind of technique had been applied on a dry-CT. This kind of technique takes the low-voltage capacitor which series with the end-screen integration into the insulating core of CTs. The technology ensure the connection point of high-voltage capacitors and low-voltage capacitor will never disconnected and the end-screen lead will grounded forever. In terms of error measurement, self-calibration and self-examination functions are achieved with adding standard and air coil next to the measuring coil. Independent power supply technique makes the device mounting more convenient.
