FIELD: measuring devices.
SUBSTANCE: invention relates to specified demand display device. Specified demand display device comprises: combined scale for indicating time and power consumption, time display unit for indicating time using combined scale, unit for gathering information on power consumption for obtaining data on power consumed to current time in given time segment for this specified value of demand, including current moment in time, display unit achieved target to indicate ratio between power consumption within given time segment registered by acquisition of information on power consumption, and required specified value established for this purpose, time segment, unit for receiving signals of alternating current to receive AC signals using alternating current pulses in power transmission line, unit for generating information on time for generating information on time based on obtained signals of alternating current, transmitting unit for transmitting generated information on time using radio waves in housing, receiving unit for receiving information on time of using radio waves transmitted inside housing, and control unit indication unit of time to time display control unit by means of obtained information on time.
EFFECT: invention allows electric energy consumers in different media to determine value of demand, which do not differ from those that are defined by electric companies, which enables to consumers determine ratio between such values demand and preset values demand and facilitate timely measures on energy saving.
