FIELD: the invention refers to the field of electric measuring technique particularly to the field of accounting of consumption of electric energy and detection of facts of its misappropriation and may be used for definition of facts of temporary unsanctioned switching of the users of electric energy to the lines of electric lighting.
SUBSTANCE: for achieving such result a system of accounting of electric energy is applied for definition of facts of temporary unsanctioned switching of users of electric energy to the lines of electric lighting. At that comparison of measured values of power with nominal values of power is made.
EFFECT: expands functional possibilities.
