    Abstract - (Show below) - (Hide below)

    Applies only to newly manufactured static watt-hour meters of accuracy classes 1 and 2, for the measurement of alternating current electrical active energy of a frequency in the range 45 Hz to 65 Hz and to their type tests only. For indoor and outdoor application consisting of a measuring element and register enclosed together in a meter case. Does not apply to watt-hour meters where the voltage across the connection terminals exceeds 600 V, portable meters and data interfaces to the register of the meter. Coverage includes normative references, definitions, tests and test conditions, relationship between ambient air temperature and relative humidity, test circuit diagram for d.c. influence test, voltage wave-form for the tests of the effect of voltage dips & short interruptions.AMD 7672 RENUMBERS TO BSEN 61036
