适用范围

This British Standard specifies requirements for newly manufactured electronic secondary meters or sub-meters which measure either electrical energies alone or electrical energies together with other electrical parameters associated with the energy. It applies to meters that measure active energy, apparent energy, reactive energy (capacitive, inductive and/or total), and ampere squared hours (A?h) and to the measurement of current, voltage, active power, apparent power, reactive power (capacitive, inductive and/or total), power factor, phase angle and frequency when measured in addition to an energy. It applies to all secondary meters and sub-meters for indoor and outdoor applications, both portable and permanently installed, for all power frequencies including d.c. It also applies to all registers, indicators, displays and outputs, and to the operation of test outputs. It does not apply to primary meters, to data interfaces to the meter, or to load survey analysers or load survey meters. The reliability aspect is not covered in this standard. Where the display and/or the memory is external or where other elements are enclosed in the meter case (such as maximum demand indicators, telemetering, time switches or remote control, etc.) this standard applies only to the section of the meter concerned with measurement.
