ELECTRICITY METERING EQUIPMENT (a.c.) - PARTICULAR REQUIREMENTS - PART 22: STATIC METERS FOR ACTIVE ENERGY (CLASSES 0,2 S AND 0,5 S) (SECOND REVISION) (IEC 62053-22:2003, MOD)
This Malaysian Standard applies only to newly manufactured static watt-hour meters of accuracy classes 0,2 S and 0,5 S, for the measurement of alternating current electrical active energy in 50 Hz or 60 Hz networks and it applies to their type tests only.
It applies only to transformer-operated static watt-hour meters for indoor applicationconsisting of a measuring element and register(s) enclosed together in a meter case. It alsoapplies to operation indicator(s) and test output(s). If the meter has a measuring element formore than one type of energy (multi-energy meters), or when other functional elements, likemaximum demand indicators, electronic tariff registers, time switches, ripple control receivers,data communication interfaces, etc. are enclosed in the meter case, then the relevantstandards for these elements also apply.
It does not apply to:
– watt-hour meters where the voltage across the connection terminals exceeds 600 V (line-to-line voltage for meters for polyphase s
