Safety requirements for electrical equipment for measurement, control, and laboratory use - Part 2-033: Particular requirements for hand-held multimeters for domestic and professional use, capable of measuring mains voltage

This document applies to electrical equipment using signals in the frequency range 3 kHz to 95 kHz to transmit or receive information on low voltage electrical systems, for electricity suppliers and distributors. In the case of equipment which includes functions other than the transmission or reception of information on LV distribution networks or installations of network users connected to the public electricity distribution network, this document applies only to that part of the equipment intended for such transmission or reception of information. Other parts of the equipment are expected to comply with the immunity standard or standards relevant to the functions of those other parts. The object of this document is to contribute to ensuring EMC in general. It specifies essential immunity requirements and test methods, including those tests which are to be performed during type-testing of MCE, for electromagnetic interference (EMI) generated on LV installations. It defines the methods and requirements for testing immunity concerning the basic function of an MCE, in relation to continuous and transient disturbances, both conducted and radiated, and electrostatic discharges. Test requirements are specified for each port considered. Furthermore it provides guidelines for the assessment of the performance of the communication function of an MCE. Normative specifications are under consideration. This document gives limits which are applicable to MCE used by electricity suppliers and distributors (e.g. DSOs) for purposes like energy management and network monitoring and automation. The levels do not however cover extreme cases which could occur in any location but with a low probability of occurrence. In special cases situations will arise where the level of disturbances could exceed the levels specified in this document, e.g. where a hand-held transmitter is used in proximity of an apparatus. In these instances special mitigation measures might have to be employed. It does not specify immunity between MCE operating in the same nominal frequency band or immunity to signals originating from power line carrier systems operating on high or medium-voltage networks. Safety considerations are not included in this document.

Varnostne zahteve za električno opremo za meritve, nadzor in laboratorijsko uporabo - 2-033. del: Posebne zahteve za ročne multimetre in druge merilnike za domačo in profesionalno uporabo, ki omogočajo merjenje omrežne napetosti - Dopolnilo A11

Ta dokument se uporablja za električno opremo, ki uporablja signale v frekvenčnem območju od 3 kHz do 95 kHz za prenos ali sprejemanje informacij o nizkonapetostnih električnih sistemih za dobavitelje in distributerje električne energije. V primeru opreme, ki poleg prenosa ali sprejema informacij o nizkonapetostnih distribucijskih omrežjih ali napravah uporabnikov omrežja, priključenih na javno distribucijsko omrežje električne energije, vključuje še druge funkcije, se ta dokument uporablja samo za tisti del opreme, ki je namenjen takemu prenosu ali sprejemu informacij. Drugi deli opreme naj bi bili v skladu s standardom odpornosti ali standardi, ki so pomembni za funkcije teh drugih delov.
Namen tega dokumenta je prispevati k zagotavljanju elektromagnetne združljivosti na splošno. Določa bistvene zahteve glede odpornosti in preskusne metode, vključno s tistimi preskusi, ki jih je treba opraviti med tipskim preskušanjem opreme MCE, za elektromagnetne motnje (EMI), ki nastanejo na nizkonapetostni napeljavi.
Opredeljuje metode in zahteve za preskušanje odpornosti v zvezi z osnovno funkcijo opreme MCE glede neprekinjenih in prehodnih motenj, tako prevodnih kot sevanih, ter glede elektrostatičnih razelektritev. Preskusne zahteve so določene za vsaka obravnavana vrata.
Poleg tega podaja smernice za oceno lastnosti komunikacijske funkcije opreme MCE. Normativne specifikacije so v obravnavi.
Ta dokument določa omejitve, ki veljajo za opremo MCE, ki jo uporabljajo dobavitelji in distributerji električne energije (npr. DSO) za namene, kot so upravljanje z energijo ter spremljanje in avtomatizacija omrežja. Vendar stopnje ne zajemajo izjemnih primerov, ki se utegnejo zgoditi na kateri koli lokaciji, čeprav je verjetnost majhna. V posebnih primerih se bodo pojavile situacije, ko bi lahko raven motenj presegla ravni, določene v tem dokumentu, npr. kadar se v bližini aparata uporablja ročni oddajnik. V takih primerih je morda treba uporabiti posebne ukrepe za ublažitev.
Ne določa odpornosti med opremo MCE, ki deluje v istem nazivnem frekvenčnem pasu, ali odpornosti na signale, ki izvirajo iz sistemov nosilcev daljnovoda, ki delujejo v visoko ali srednjenapetostnih omrežjih.
Varnostni vidiki niso vključeni v ta dokument.

Overview

EN IEC 61010-2-033:2021/A11:2021 is a CLC (CENELEC) amendment to the European safety standard for hand-held multimeters and other portable meters capable of measuring mains voltage. The amendment updates particular requirements and normative references and clarifies test and documentation expectations. The published annexes also connect the standard to EU regulatory objectives (Low Voltage Directive).

Primary focus: safety and electromagnetic compatibility (EMC) aspects for portable electrical test equipment used in domestic and professional environments, including type-testing requirements and assessment of communication functions where applicable.

Key Topics and Requirements

• Scope (as provided): applies to electrical equipment using signals in the 3 kHz–95 kHz band to transmit/receive information on low-voltage (LV) distribution systems, especially for electricity suppliers and distributors (e.g., DSOs). Where equipment includes other functions, the standard applies only to the part intended for LV communication.
• EMC immunity requirements: specifies essential immunity tests and methods (continuous and transient disturbances; conducted and radiated interference; electrostatic discharge) for Metering Communication Equipment (MCE) ports and basic functions.
• Type-testing: identifies tests to be performed during type-testing of MCE and gives assessment guidelines for communication performance under disturbance.
• DC voltage test amendment: the voltage tester used in testing shall have a regulated output capable of maintaining the test voltage within ±5% throughout the test.
• Materials guidance: manufacturers are advised to consider the expected service life of hand-held multimeters when selecting insulating materials (note added).
• Limitations and exclusions: provided disturbance limits cover common locations and use cases, but do not address rare extreme interference scenarios, immunity between MCEs in the same nominal band, or immunity to signals from PLC systems on high/medium-voltage networks. Safety (electrical shock, etc.) considerations are handled in related parts of IEC 61010 and are not the focus of this amendment.
• Regulatory linkage: addition of Annex ZA (normative references) and Annex ZZ (informative relationship to Directive 2014/35/EU - Low Voltage Directive) to support presumption of conformity when cited in the Official Journal.

Applications and Who Uses It

• Manufacturers of hand-held multimeters and portable meters - design, material selection, test programs, and technical files.
• Test laboratories and certification bodies - type-testing and EMC immunity testing procedures.
• Utility companies and DSOs - selecting MCE and communication-capable meters for energy management, network monitoring and automation.
• Compliance engineers and regulatory authorities - demonstrating conformity with EU Low Voltage Directive and harmonized safety expectations.

Related Standards

• EN IEC 61010-1 (general safety requirements)
• IEC 61010-031 (hand-held probes and assemblies)
• EN IEC 61010-2-032 (hand-held current sensors)
• IEC 61180 (high-voltage test techniques)

Keywords: EN IEC 61010-2-033:2021/A11:2021, hand-held multimeters, mains voltage, safety requirements, EMC immunity, metering communication equipment, type-testing, Low Voltage Directive.
