FIELD: electric supply engineering, possible use in electric networks for checking serviceability and precision of measurements of panel for counting electric power.
SUBSTANCE: in accordance to proposed method during certain time, during which load remained unchanged, number of rotations of counter disk is counted, phase currents are measured, voltages, cosφ or power, consumed in each phase. On basis of received values its total sum is calculated, and also electric energy is determined, counted by counter, on basis of technical speed of the latter. These connected are compared and on basis of received data serviceability of panel is evaluated.
EFFECT: decreased of number and simplification of operations performed during control of panel for counting delivered electric energy.
