| Predmet normy: | This document applies only to static watt-hour meters of accuracy classes A, B and C for the measurement of direct current electrical active energy in DC systems and it applies to their type tests. NOTE 1 For general requirements, such as construction, EMC, safety, dependability etc., see the relevant EN 62052 series or EN 62059 series. This document applies to electricity metering equipment designed to: - measure and control electrical energy on DC electrical networks with voltages up to 1 500 V; NOTE 2 Meters for unearthed DC supplies and meters for three-wire DC networks are within the scope of this document. - form a complete meter including the legally relevant display of measured values; NOTE 3 Electrical energy meters constructed from separate parts as described in WELMEC Guide 11.7:2017 are included. - operate with integrated or detached legally relevant displays; - optionally, provide additional functions other than those for measurement of electrical energy. |
