FIELD: electrical equipment.
SUBSTANCE: invention relates to the electrical equipment. Technical result consists in increase in the computing system accuracy and is achieved by the fact, that the system comprises the first device, comprising the primary conductor voltage measuring element, measured voltage sample obtaining means, the first message transmitting means, and the representative voltage values set of variables determining means, based on the measured during the given transmission period voltage; at least one second device, having the current sensor for the connected to the primary conductor secondary conductor current determining, the measured current sample obtaining means; and the said energy calculation element, comprising the first message receiving means and configured to calculate energy during the given transmission period based on associated with the given transmission period the said data array and the current strength samples. Determining means is configured to determine the said data array based on the correction coefficient, which depends on the voltage representative value only for each voltage period, during which the said value exceeds the threshold.
EFFECT: technical result consists in increase in the computer system accuracy.
