| Resumen: | IEC 62052-11:2020 (E) specifies requirements and associated tests,
with their appropriate conditions for type testing of AC and DC
electricity meters. This document details functional, mechanical,
electrical and marking requirements, test methods, and test
conditions, including immunity to external influences covering
electromagnetic and climatic environments. 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 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); • be installed in a specified matching
sockets or racks; • optionally, provide additional functions other
than those for measurement of electrical energy. 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 and the relevant IEC 62053 series documents only if
such meters and their LPITs are tested together as directly
connected meters. This document is also applicable to auxiliary
input and output circuits, operation indicators, and test outputs
of equipment for electrical energy measurement. This document also
covers the common aspects of accuracy testing such as reference
conditions, repeatability and measurement of uncertainty. This
document does not apply to: • meters for which the voltage
line-to-neutral derived from nominal voltages exceeds 1 000 V AC,
or 1 500 V DC; • meters intended for connection with low power
instrument transformers (LPITs as defined in the IEC 61869 series
of standards) when tested without such transformers; • metering
systems comprising multiple devices (except of LPITs) physically
remote from one another; • portable meters; • meters used in
rolling stock, vehicles, ships and airplanes; • laboratory and
meter test equipment; • reference standard meters; • data
interfaces to the register of the meter; • matching sockets or
racks used for installation of electricity metering equipment; •
any additional functions provided in electrical energy meters. This
document does not cover measures for the detection and prevention
of fraudulent attempts to compromise a meter’s performance
(tampering). This second edition cancels and replaces the first
edition published in 2003, and its amendment 1:2016. This edition
constitutes a technical revision. This edition includes the
following significant technical changes with respect to the
previous edition: a) Removed all meter safety requirements; the
meter safety requirements are covered in IEC 62052-31:2015; b)
Included requirements for meter power consumption and voltage
requirements from IEC 62053-61; IEC 62053-61 is withdrawn; c)
Included requirements for meter symbols from IEC 62053-52; IEC
62053-52 is withdrawn; d) Included requirements for meter pulse
output devices from IEC 62053-31; IEC 62053-31 is withdrawn; e)
Added new requirements and tests including: meters with detached
indicating displays, and meters without indicating displays, meter
sealing provisions; measurement uncertainty and repeatability;
time-keeping accuracy; type tes
