FIELD: electricity.
SUBSTANCE: control system includes the first sensor (112, 200) located at some place in the line of phase conductor (104, 602) and the second sensor (112, 200) located at some second place in the line of phase conductor. The first sensor contains means for generation of the first data set of synchronised phasor. The second sensor contains means for generation of the second data set of synchronised phasor. Control system includes processor containing means for receipt of the first and second data sets from synchronised phasor. Besides processor contains means for identification of voltage (Vp) at side of the primary winding of at least one distribution transformer (110, 600) connected electrically to the line of phase conductor on the basis of voltage (Vs) at side of the secondary winding of distribution transformer. Voltage at side of the primary winding is determined on the basis of electric meter data coming from variety of measured loads (608, 610) connected electrically to the secondary winding side of distribution transformer. Besides processor contains means to determine at least one condition of operation for the phase conductor line based on the first and second data sets of synchronised phasor and voltage at the primary winding side.
EFFECT: improved accuracy.
