規格概要 IEC 62053-41:2021 applies only to static watt-hour meters of accuracy classes 0,5 and 1 for the measurement of DC electrical energy in DC systems, and it applies to their type tests only.
This document applies to electricity metering equipment designed to:
measure and control electrical energy on electrical networks with two poles where one of the poles is connected to earth and with voltage up to 1 500 V DC;
have all functional elements, including add-on modules, enclosed in, or forming a single meter case with the exception of indicating displays;
operate with integrated or detached indicating displays, or without an indicating display;
be installed in a specified matching socket or rack;
optionally, provide additional functions other than those for measurement of electrical energy.
They may be used for measuring DC electrical energy, amongst others, in the following application areas:
in EV (electrical vehicle) charging stations or in EV charging infrastructures, if the measurement is placed on the DC side;
in information technology (IT) server farms;
in DC supply points for communication equipment;
in low voltage DC networks for residential or commercial areas, if the measurement is placed on the DC side;
in solar PV (photovoltaic) systems where DC power generation is measured;
in DC supply points for public transport networks (e.g. trolleybus, etc.).
Meters designed for operation with low power instrument transformers, LPITs as defined in the IEC 61869 series, may be tested for compliance with this document only if such meters and their LPITs are tested together and meet the requirements for directly connected meters.
This document does not apply to:
meters for which the voltage between the two poles, where one of the poles is connected to earth, exceeds 1 500 V DC;
