Abstract
Устройство поверки однофазных средств измерений электрической мощности и энергии, содержащее источник «фиктивной» мощности, эталонный счетчик, трансформатор напряжения, включающий одну первичную обмотку и несколько вторичных обмоток, выход канала напряжения источника «фиктивной» мощности соединен с первичной обмоткой трансформатора, выход каждой вторичной обмотки трансформатора напряжения подключен к параллельной цепи каждого поверяемого средства измерений, выход канала тока источника «фиктивной» мощности соединен с последовательной цепью эталонного счетчика и подключен к последовательно соединенным последовательным цепям поверяемых средств измерений, отличающееся тем, что дополнительно введен коммутатор, контрольный выход которого подключается к любой из вторичных обмоток трансформатора, при этом параллельная цепь эталонного счетчика подключена к контрольному выходу. A device for checking single-phase means of measuring electric power and energy, containing a source of “dummy” power, a reference meter, a voltage transformer including one primary winding and several secondary windings, the output of the voltage channel of the source of “dummy” power is connected to the primary winding of the transformer, the output of each secondary winding a voltage transformer is connected to a parallel circuit of each verified instrument, the output of the current channel of the source of "fictitious" power is connected to Flax reference meter circuit and connected to the series connected sequential circuits calibrated measuring means, characterized in that additionally introduced a switch control output of which is connected to any of the secondary windings of the transformer, the parallel circuit a reference counter connected to the control output.
