Two transformer substations were built at the basement floor, supported by two DG sets, in order to provide reliable power supply for state of art office spaces.
Transformer substations are 10/0.4kV, 1x1250kVA + 1x1600kVA, both and supported by DG sets with rated power of 1825kVA.
For the highest priority consumers uninterruptible power supply are provided via two UPS devices, 160kVA each.
Low voltage PCCs were predicted all according to SRPS IEC 61439-1&2 and arc control system acc. to IEC 61641.
