Point of commercial accounting of pillar PKU-S makes accounting of active and reactive energy of the direct and opposite direction in alternating current circuits energized from 6 to 10 kV, rated current to 630 A and with a frequency of 50 Hz. It can be used as a part of the automated monitoring systems and accounting of the electric power (ASKUE) as the transmitter of data on master station of control, distribution and accounting of the electric power.
