Required Interfaces on The Transformer Tank
    As it requires very few interfaces, the TRANSFORMER PROTECTOR can be easliy adapted to any
    existing or new transformers.

    Document 10, details every interface required for adaptation on new transformers.

    During the design stage, transformer manufacturers are informed of the necessary interfaces in order to equip the transformer
    tank with:

  • One flange, on the transformer cover, if allowed by the High Voltage clearances, or on side of the tank, 20 cm below the cover. Its diameter varies according to the Depressurisation Set selected according to the transformer characteristics. Two flanges at opposite side may be requested in some cases.

  • One support for the Depressurisation Set.

  • One or several valves for nitrogen injection, located at the bottom of the transformer.

    Documents 11, details every possible configuration for adaptation on transformers already in service.

    SERGI always uses existing transformer interfaces in order to avoid tank drilling and machining.

    Oil sampling or filtering valves at the bottom of the tank are adapted to inject nitrogen inside the transformer through suitable
    T-pieces.

    The Control Panel is mounted in the control room or relay house. The Nitrogen Cabinet should be mounted close
    to the transformer.






TP RETROFITTING

 

When the TRANSFORMER PROTECTOR is retrofitted on service transformers, existing interfaces are always used, tank drilling and machining are avoided.
