Abstract
One of the electrode in Haenam converter, which is role of rectifier in Jeju-Haenam HVDC system is destroyed and we found many cracks at another electrode and we also found many cracks in Jeju converter station, which is role of inverter of Jeju-Haenam. HVDC system, there is no exact reason for these phenomenon, even though the life cycle of these electrode is 40 years. So, the experts for HVDC system in KEPCO and Anotec corporation, which is manufacturer of electrode, would perform research for the reason of electrode disorder. In this paper analyze the reason of electrode disorder and corrosion in high voltage direct current system.
