AC power equipment
Transformer substations
A complete transformer substation (CTS) is designed to receive, convert and distribute three-phase alternating current with a frequency of 50 Hz and a voltage of up to 35 kV.
The CTS may include the following components:
- medium voltage switchgear 35 (10; 6) kV (MVS);
- power transformer 35 (10; 6) / 0.4 kV;
- busbar trunking;
- low voltage switchgear 0.4 kV (LVS).
Corporation "ELCOR" produces LV switchboards of CTS, and also offers complex supply of equipment for CTS including dry power transformers and high-voltage switchgears.
Low voltage switchboards can be equipped with components for power measurement and metering systems, as well as monitoring systems based on programmable logic controllers with the ability to transfer data to the upper level and remote control.
