BS EN 50470-4:2023
This standard BS EN 50470-4:2023 Electricity metering equipment is classified in these ICS categories:
- 91.140.50 Electricity supply systems
This document applies only to static watt-hour meters of accuracy classes A, B and C for the measurement of direct current electrical active energy in DC systems and it applies to their type tests. NOTE 1 For general requirements, such as construction, EMC, safety, dependability etc., see the relevant EN 62052 series or EN 62059 series. This document applies to electricity metering equipment designed to: - measure and control electrical energy on DC electrical networks with voltages up to 1 500 V; NOTE 2 Meters for unearthed DC supplies and meters for three-wire DC networks are within the scope of this document. - form a complete meter including the legally relevant display of measured values; NOTE 3 Electrical energy meters constructed from separate parts as described in WELMEC Guide 11.7:2017 are included. - operate with integrated or detached legally relevant displays; - optionally, provide additional functions other than those for measurement of electrical energy. They can be used for measuring DC electrical energy, amongst others, in the following application areas: - in EV (electrical vehicle) charging stations or in EV charging infrastructure (also called EVSE, electric vehicle supply equipment), if energy is measured on the DC side; - in solar PV (photovoltaic) systems where DC power generation is measured; - in low voltage DC networks for residential or commercial areas, if energy is measured on the DC side, including similar applications like information technology (IT) server farms or DC supply points for communication equipment; - in DC supply points for public transport networks (e.g. for trolleybuses); - in mobile applications on vehicles for e-road (electric road) systems. Meters designed for operation with external DC instrument transformers, transducers or shunts can be tested for compliance with this document only if such meters and their transformers, transducers or shunts are tested together and meet the requirements for directly connected meters. Requirements in this document and in EN IEC 62052 11:20211 applying to meters designed for operation with DC LPITs also apply to meters designed for operation with external instrument transformers, transducers or shunts. NOTE 4 Modern electricity meters typically contain additional functions such as measurement of voltage magnitude, current magnitude, power, etc.; measurement of power quality parameters; load control functions; delivery, time, test, accounting, recording functions; data communication interfaces and associated data security functions. The relevant standards for these functions could apply in addition to the requirements of this document. However, the requirements for such functions are outside the scope of this document. NOTE 5 Product requirements for power metering and monitoring devices (PMDs) and measurement functions such as voltage magnitude, current magnitude, power, etc., are covered in EN IEC 61557-12:2022. However, devices compliant with EN IEC 61557-12:2022 are not intended to be used as billing meters unless they are also compliant with EN IEC 62052 11:20211 and this document. NOTE 6 Requirements for DC power quality (PQ) instruments, DC PQ measuring techniques, and DC PQ instrument testing are under discussion and will be specified in other standards. This document does not apply to: — portable meters; NOTE 7 Portable meters are meters that are not permanently connected. — meters used in rolling stock (railway applications), ships and airplanes; NOTE 8 DC meters for rolling stock are covered by other standards, e.g. by the EN 50463 series.
