Adaptation to Transformers   Required interfaces on the transformer tank As it requires very few interfaces, the Transformer Protector can be easily adapted to any existing or new transformers. For new transformers Document 9 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: • 1 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 Depressurization Set selected according to the transformer characteristics. 2 flanges at opposite side may be requested in some cases. • 1 support for the Depressurization Set. • 1 or several valves for nitrogen injection, located at the bottom of the transformer.   For existing transformers If existing transformer tanks are not equipped with a flange or a manhole on the side of the transformer, the Depressurization Set is adapted to the Pressure Relief Valve flange with a T-piece. In that case, the Vertical Decompression Chamber is slightly different as it contains 2 pipes: for the explosive gases (E) and for the oil (D). A - Isolation Valve B - Absorber C - Rupture Disk D - Oil Evacuation Pipe E - Gas Evacuation Pipe F - Vertical Decompression Chamber By always using existing transformer interfaces, tank drilling and machining is avoided. Oil sampling or filtering valves at the bottom of the tank are adapted to inject nitrogen inside the transformer through suitable T-pieces. Installation Click for document #11 The Control Panel is mounted in the control room or relay house. The Nitrogen Cabinet should be mounted close to the transformer.
