This paper considers the distributed capacitance of transmission lines to research the protection of high-voltage direct-current (HVDC) transmission line. According to the superposition theorem. the post-fault superimposed network of HVDC system is used to analyse the characteristic of the root mean square (RMS) of specific frequency voltage (SFV) during the transient period of intern... https://midwaysportes.shop/product-category/bumper-plates/
