Electricity metering equipment (a.c.). Particular requirements - Pulse output devices for electromechanical and electronic meters (two wires only) subscription-only ISO 18520 aims at fostering1 Scope This part of IEC 62053 is applicable to passive, two wire, externally powered pulse output devices to be used in electricity meters as defined by the relevant standards of technical committee 13 (see normative references) as well as future standards for static VA hour meters. Such pulse output devices are used to transmit pulses, representing a finite energy quantity, to a receiver (e. g. a tariff device).
