Inertaire® oil preservation systems

The Inertaire® System of Hitachi Energy provides a regulated nitrogen gas supply to the gas space of power transformers. The user inserts a nitrogen gas cylinder into the Inertaire® compartment, makes the necessary gas connections, and the Inertaire® system will maintain a positive pressure nitrogen gas blanket in the transformer’s gas space. The user can set the pressure range, and the Inertaire® system will maintain the set pressure range by adding nitrogen or venting overpressure to the atmosphere. The Inertaire® System contains alarms to alert the user to pressures or empty nitrogen bottles.
