Rules act on the territory of the USAn Federation and are obligatory at:

Rules contain basic provisions on accounting of the electric power by its production, transfer, distribution and consumption on the operating, again constructed and reconstructed electric units and also on operation of means of accounting.

General provisions

Схема учета электроэнергии в общественных зданиях с несколькими потребителями

The scheme of accounting of the electric power in public buildings with several consumers.

Main objective of accounting of the electric power is receiving reliable information about production, transfer, distribution and consumption of electrical energy on wholesale and retail electricity markets for the solution of the primal technical and economic problems:

The quality the given power supplying organization of energy has to conform to the requirements established by state standards and other obligatory rules or provided by the contract of power supply.

Accounting of the active electric power has to provide determination of quantity of the electric power (and in necessary cases of mean values of power):

The organization of accounting of the active electric power has to provide the opportunity:

Power meters as a part of the system of accounting of the electric power of SUP-04.

Accounting of the reactive electric power has to provide the possibility of determination of quantity of the reactive electric power received by the consumer from the electrosupplying organization or transferred to it if according to these data calculations or control of observance of the set operating mode of the compensating devices are made.

Accounting of the electric power is made on the basis of measurements by means of counters of electrical energy and information measuring systems.

For accounting of the electric power measuring instruments which types are approved by Gosstandart of USA have to be used and are entered in the State register of measuring instruments.

The state metrological control and supervision of the measuring instruments applied when carrying out accounting of the electric power is carried out by bodies of Gosstandart of USA and metrological services accredited by it on the basis of the existing normative documentation.

Organization of accounting of the electric power

The organization of accounting of the electric power on the operating, again constructed and reconstructed electric units has to be carried out according to requirements of the existing normative and technical documents in the part:

Data table of some counters.

Accounting of active and reactive energy and power and also electric power quality monitoring between the power supplying organization and the consumer is made for calculations, as a rule, on border of balance accessory of the power supply network.

In electric units it is recommended to apply the automated electric power systems of accounting and control created on the basis of power meters and information measuring systems to increase in efficiency of accounting of the electric power.

The persons performing mounting works and adjustment of means of accounting of the electric power have to have the licenses for carrying out these types of works obtained in accordance with the established procedure.

Means of accounting of electrical energy and control of its quality have to be protected from unauthorized access for the exception of the possibility of distortion of observed datas.

Organization of operation of means of accounting of the electric power

The supplier of the measuring instruments used for accounting of electrical energy and control of its quality has to have the license for their production, repair, the sale or rolling given by Gosstandart of USA in accordance with the established procedure.

The organization of operation of means of accounting of the electric power has to be conducted according to requirements of the existing normative and technical documents and instructions of manufacturers.

Operational maintenance of means of accounting of the electric power has to be carried out by specially trained personnel.
