This standard applies to the production of passive low-power current transformers (converters) (hereinafter referred to as passive MMCTs) with an analog output and contains only additional requirements for passive MMCTs that are not included in other parts of this series of standards. The basic requirements for the production and testing of passive MMTTs are given in [1]. In this case, it is also necessary to be guided by the requirements of GOST IEC 61869-6 and this standard, which contains additional requirements. This standard specifies the accuracy requirements for passive analog output MMCTs intended for use with electrical measuring instruments or electrical protective devices over a rated frequency range of 15 to 100 Hz.
