Scope

This document specifies product safety requirements for electrical energy measurement and control equipment. Note 1: See relevant standards for other requirements. This document applies to newly manufactured metering equipment designed to measure and control electrical energy in networks of 50 Hz or 60 Hz and voltages not exceeding 600 V. All functional units of the device, including additional modules, are enclosed within a single housing or form a single entity. Note 2: The voltage mentioned above is the phase-to-neutral voltage derived from the nominal voltage, see Table 7. This document also applies to metering equipment that includes power control switches and load control switches, but those switches are only electromechanical switches. Note 3: For components and assemblies see Chapter 13. When the equipment is designed to be installed in a dedicated matching socket-outlet, the requirements for the equipment only apply when it is installed in the dedicated matching socket-outlet and shall be applied when the equipment is installed in the dedicated matching socket-outlet Experiment with it. However, the requirements for sockets and for plugging or unplugging equipment from sockets are outside the scope of this document. This document also applies to auxiliary input and output circuits. Note 4: Examples are pulse input and output circuits, control input and output circuits and instrument data exchange circuits. This document distinguishes: --- Electromechanical energy meters, static energy meters, and rate and load control equipment; --- Directly connected to electric energy meters, connected to electric energy meters through current transformers, connected to electric energy meters through current and voltage transformers --- Class I protective equipment and Class II protective equipment; --- Wall or cabinet-mounted equipment, rack-mounted equipment and panel-mounted equipment; --- Indoor use equipment and outdoor use equipment. Equipment used with electrical energy measurement and control equipment may be subject to additional safety requirements. See Chapter 13. Note 5: Examples are telecommunication modems and user information units. This document does not apply to: --- Equipment whose phase-to-neutral voltage derived from the nominal voltage exceeds 600V; --- Portable energy meters; Note 6: Portable energy meters are non-permanently connected energy meters. --- laboratory and mobile energy meter test equipment; --- reference standard table. The security requirements of this document are based on the following assumptions. --- Metering equipment has been installed correctly. - Energy metering equipment is usually used by unskilled individuals, including meter readers and consumers of electrical energy. In many cases, equipment is freely accessible after installation. Its terminal cover cannot be removed without tools and its case cannot be opened without removing the seal. - During normal use, all terminal covers, covers or barriers that provide protection against access to HAZARDOUS LIVE PARTS are in place. --- For the installation, configuration, maintenance and repair of the energy meter, it may be necessary to remove the terminal cover, case or barrier (or part thereof), so that the hazardous live parts become accessible. These jobs are carried out by skilled craftsmen who have undergone appropriate training, 1 GB/T17215.231—2021/IEC62052
