DANSK DSF/PREN IEC 62053-41 PDF

This part of IEC 62053 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. NOTE 1: For other general requirements, such as safety, dependability etc., see the relevant IEC 62052 or IEC 62059 standards. 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 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.
