A transformer during operation is subjected to changes in temperature caused either by the transformer's operation itself or atmospheric conditions. Temperature changes have direct effects on pressures inside the transformer tank. Negative pressures (vacuum) inside the tank create suction, which can draw moisture into the transformer.
The ARES Nitrogen Systems, are designed to provide a continuous constant low positive pressure inside the transformer tank, by purging Nitrogen between the oil and the tank cover (Gas Space).
The Ares cabinets are easy to install. They can be mounted on the transformer or on a stand beside the transformer.
The Inertaire System (tm) includes all of the pressure regulating controls needed to maintain a positive pressure nitrogen atmosphere in the gas space of the transformer. This nitrogen blanket protects the transformer’s oil from deterioration caused by exposure to moisture or oxygen. When the gas space pressure falls below the low pressure limit, the Inertaire System (tm) automatically feeds fresh nitrogen into the transformer gas space until the pressure is restored to a value above the low pressure limit. When the pressure exceeds the high pressure limit, the system vents the excess pressure to the atmosphere through a relief valve.
