Repeated damage to the "Bar" 330 kW substation - the transformer and the technical infrastructure of the substation were damaged.

At night, a jet UAV hit the 330 kV "Bar" substation again in the Shirokoy area of the Vinnytsia region. The impact damaged the facility's transformer circuit: the power transformer caught fire, and at the same time the fire broke out in a nearby technical building with an area of about 120 square meters.
49.0828954, 27.7442618.
This is already a repeated attack on the substation in the last two days. The previous attack damaged the equipment of the 110 kW external switch. The current chapter has already affected another key element of the object - the change in power and the technical infrastructure associated with it.
The resulting image allows you to confidently assess the condition of the transformer.
The consequences of intense oil burning are clearly visible on the unit: the body and radiator batteries are covered with a dense layer of soot, the upper part of the tank, the connections and the expansion tank are severely thermally damaged. The cooling system equipment and external accessories were burned. The tank itself has kept its basic geometry, but for a power transformer that doesn't mean it remains active.
After such a fire, the unit was taken out of normal operation. Thermal effects affect the insulation system, bushings, transformer oil, oil lines, cooling system, on-load tap changer, electrical connections and internal winding insulation. Even without complete destruction of the tank, further operation of such equipment is impossible without deep defects and restoration repairs. The condition of cellulose-oil insulation is particularly critical. When it overheats, it loses its electrical strength, and the thermal decomposition products of the oil sharply worsen its insulating properties. For high voltage transformers, this means that you cannot safely return to operating voltage without full diagnosis.
The fire in the technical structure damaged the facility's secondary systems.
