Abstract:  Among the relay protections, overcurrent relay protections have a large proportion. In this paper, technical effect of overcurrent relay protection settings (high-voltage lines) is proposed and analyzed. And then technical efficiency for estimating this setting is purposed and investigated. For both above criteria, the probability statistical algorithms are used to calculate. Finally base on these criteria, setting options and recommendations for setting of overcurrent relay protection is given.
