| Abstract: | The reliability of high-frequency channel plays a decisive role in correct operation of carrier current protection.Aiming at oversize attenuation problem of 110 kV Xinsai line high-frequency channel,the work capability of wiring in high-frequency channel is checked,and interference factors of ground backward-wave are analyzed.Fitting operating frequency of Xinsai line high-frequency channel is decided through sweep checking of the channel.As a result,the attenuation of high-frequency channel is decreased effectively. |
