What is BS 8431 - Electrical static meters specification about ?

BS 8431 is an International Standard that specifies electrical static meters for secondary metering and sub ‑ metering. BS 8431 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. BS 8431 applies to meters that measure active energy, apparent energy, reactive energy (capacitive, inductive, and total), and ampere squared hours (A²h) and to the measurement of current, voltage, active power, apparent power, reactive power (capacitive, inductive, and total), power factor, phase angle, and frequency when measured in addition to energy. BS 8431 also 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.
