Scope

This standard specifies the marking and technical parameters, standard rated values, and usage conditions of high-gradient and low-residual-voltage metal oxide resistors (hereinafter referred to as resistors) used in AC systems, as well as technical requirements, testing requirements, type testing, routine testing, sampling testing, and acceptance testing. This standard applies to high-gradient and low-residual-voltage metal oxide resistors used in AC metal oxide surge arresters.
