ABSTRACT: At present the detecting of ultra
high voltage direct current (UHVDC) earth electrode frequently uses manual
inspection. This method can't get the real-time operational data of the earth
electrodes, and meanwhile, the labor cost is very high. In order to satisfy the
security needs of UHVDC, this paper designs an on-line monitoring system for UHVDC earth electrode. By 3G wireless communication-technologies, the
system can monitor remotely many kinds of data such as the value of the
grounding current, water level of the observation well, soil temperature and
humidity near the earth electrode, the micro-climate around the earth electrode
site, video data, etc. Through analyzing the datum, the system has broad
prospect on fault detection and life evaluation of the UHVDC earth electrode.
