FIELD: electrical engineering.
SUBSTANCE: implementation of the claimed solution is the ability to control the metrological characteristics of the meter during its use (without removal from the place of operation), expansion of the range of controlled parameters, as well as increase in the metrological reliability of the meter (the source of the test effect of the required accuracy, creating fictitious power, has a sufficiently high reliability).
EFFECT: improved performance of electric meters
