AS 62053.61:2018 Electricity metering equipment (a.c.)— Particular requirements
1 Scope
This International Standard applies only to newly manufactured ”combined meters”, measuring more than one type of electric energy (e.g. active and r eactive) and m eters integrating additional functions which are not in the scope of the IEC 60687, IEC 61 036, IEC 61 268 standards and the s tandard in preparation for static apparent energy meters; these additional functions, all related to electric energy metering are, for instance, maximum demand indicator,time switches, ripple control or radio receivers, etc.
When other devices and f unctions not r elated to elec tric energy metering and billing are enclosed in the s ame meter case (such as power line c arrier devices, load c urve recording devices, telephone and radio transceiver or network current and voltage m easurement and analysis devices, etc.) this standard applies only to the ener gy metering and processing section.
For all the meter characteristics and functions already described in existing standards, these standards will apply for the corresponding characteristics and functions.
