摘要
An electric power transmission line with protection devices against lightening overvoltages in the form of a lighting arrester with a surface discharge. Having a relatively long discharge path, the impulse lightening flashover does not lap over a power arc of operational frequency and, after passing of the lightening overvoltage impulse current, the line will continue a trouble-free operation without being disconnected. Simple and reliable arrester designs are disclosed among which are fittings with dielectric covers and insulators, integrating their direct functions with the lightening arrester's functions.
