AC power equipment
Auxiliary power supply switchboards for energy
Auxiliary power supply switchboards are used for distribution of electrical energy of three-phase alternating current with a frequency of 50 Hz and a voltage of 0.4 kV in the auxiliary power supply networks of power stations and substations.
Auxiliary switchboards produced by “ELCOR” Corporation are equipped with components of electricity measurement and energy commercial accounting systems, as well as monitoring systems based on programmable logic controllers with the ability to transfer data to the upper level and remote control.
