SERIES OF TRANSFORMER EXPLOSIONS AVOIDED
A cyber attacker can manipulate simultaneously multiple substations for destroying transformers by overload, potentially affecting electricity distribution in very large regions.
The TP is designed to prevent transformers from tank rupture, avoiding explosions and fires. After a TP activation, transformers have no permanent tank deformation and can be repaired on site quickly. Consequently, the TP is saving long supply time for ordering and installing new transformers, allowing the power system back in service much faster especially for large transformer fleets.
