Performance of Transmission Line | Electrical4U· Like other electrical system, the transmission network also will have some power loss and voltage drop during transmitting power from sending end to receiving end. Hence, performance of transmission line can be determined by its efficiency and voltage regulation. Voltage regulation of transmission line is measure of change of receiving end voltage from no-load to full load condition.

The operational experience from existing HVDC stations ... operational experience from existing HVDC stations, from 250 to 600 kV, has shown that the flashover rate of these stations has no direct correlations to the voltage levels of the stations. It has also shown that there is no tendency and need to choose a higher value for the specific creepage distance because of higher voltage level. With suitable design, a very low flashover rate of 0.05 ...
