This standard specifies that in three-phase three-wire circuits and three-phase four-wire circuits, the bells transmitted from watt-hour meters with transmitters and reactive watt-hour meters with transmitters used in combination with instrument transformers are received. This specification specifies separate display devices that display power consumption, reactive power consumption, and maximum power demand, as well as these multi-circuit integrated display devices (hereinafter referred to as display devices). Note that matters other than those stipulated in this standard are in accordance with AS C 1210 (General Rules for Electric Energy Metering). Additionally, for multi-circuit integrated display devices, this standard is applied under the total amount of addition only. In this standard, the permissible limits for display errors and total display errors due to the drive device and the combination of the drive device and transformer are specified in Annex 1, and the electric energy display device for centralized meter reading is specified in Annex 2.
