Three-phase combined arrester is a kind of over-voltage protector
developed with the development of single. The combined arrester
provides protection between phase phase and phase ground at the
same time. With the traditional method, phase phase and phase
ground were connected by surge arrester separately, which uses six
arrester in total. The key of three-phase combined arrester
technology is to provide a connection mode, the protection is
implemented with four arrester instead of six arrester. It can
protect the insulation of electric equipment between phase phase
and phase ground from damaged by over-voltage.
Three-phase combined arrester with discharge logger, besides the
protection of over-voltage, can accurately record, store and
display the action history of the arrester so as to achieve an
effective monitoring to the system.
