Electricity metering equipment - General requirements, tests and test conditions - Part 31: Product safety requirements and tests
| 분야 | TC 13 : Electrical energy measurement and control |
|---|---|
| 적용범위 | IEC 62052-31:2024 specifies general safety requirements and associated tests, with their appropriate conditions for type testing of directly connected, transformer-operated or transducer-operated AC and DC electricity meters and load control equipment. This document applies to electricity metering equipment designed to: • measure and control electrical energy on electrical networks (mains) with voltage up to 1 000 V AC, or 1 500 V DC; • have all functional elements, including add-on communication modules, enclosed in, or forming a single meter case with exception of indicating displays; • operate with integrated displays (electromechanical or static meters); • operate with detached indicating displays, or without an indicating display (static meters only); • wall-mounted or to be installed in specified matching sockets or racks; • optionally, provide additional functions other than those for measurement of electrical energy. This document also applies to transducer-operated meters or meters designed for operation with Low Power Instrument Transformers (LPIT) or sensors (as defined in the IEC 61869 series). When equipment in scope of this document is designed to be installed in a specified matching socket, then the requirements apply to, and the tests are performed on, equipment installed in its specified matching socket. However, requirements for sockets and inserting / removing the meters from the socket are outside the scope of this document. This document is also applicable to auxiliary input and output circuits, operation indicators, and test outputs of equipment for electrical energy measurement. Equipment used in conjunction with equipment for electrical energy measurement and control may need to comply with additional safety requirements. See also Clause 13. This document does not apply to: • meters rated to operate with voltage exceeding 1 000 V AC, or 1 500 V DC; • metering systems comprising multiple devices physically remote from one another; • portable meters; • meters used in rolling stock, vehicles, ships and airplanes; • laboratory and mobile meter test equipment; • reference standard meters; • conventional or low power instrument transformers; • equipment with solid-state or other non-electromechanical supply and load control switches. The safety requirements of this document are based on the following assumptions: • metering equipment has been installed correctly; • metering equipment is used generally by ordinary persons, including meter readers and consumers of electrical energy. In many cases, it is installed in a way that it is freely accessible. Its terminal covers cannot be removed, and its case cannot be opened without removing seals (if present) and using a tool; • during normal use all terminal covers, covers and barriers providing protection against accessing hazardous live parts are in place; • for installation, configuration, maintenance and repair it may be necessary to remove terminal cover(s), (a part of) the case or barriers so that hazardous live parts may become accessible. Such activities are performed by skilled persons, who have been suitably trained to be aware of working procedures necessary to ensure safety. Therefore, safety requirements covering these conditions are out of the Scope of this document. This second edition cancels and replaces the first edition published in 2015. This edition constitutes a technical revision. Please see the foreword of IEC 62052-31 for more details |
