Repeated damage to the 330 kV substation.
A jet UAV hit the "Bar" substation again in the Vinnytsia area, damaging an electrical transformer and technical infrastructure. The attack caused a fire that covered about 120 square meters of a nearby building.
This is the second hit in two days; The previous attack hit the 110 kV switch. The current damage renders the main transformer inoperative due to thermal destruction of insulation and cooling systems. A fire also destroyed secondary control circuits and relay protection equipment.
The cumulative loss of distribution equipment, transformers and automation systems severely limits network flexibility and increases the strain on the remaining assets.
