1 Scope
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 parts of IEC 62052 or IEC 62059.
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;
NOTE 2 There are DC networks with other configurations or with more than 2 poles (for example networks with earth and both a positive and a negative pole).
• 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; ...
