DESCRIPTION

Principles


The TRANSFORMER PROTECTOR is a concept that can be applied to all oil-filled transformers up to 1 000 MVA and larger.It serves to:

  • Depressurise tanks within milliseconds

  • Avoid contact between air (oxygen) and the evacuated explosive gases (Hydrogen, Acetylene, etc.)

  • Separate gases from the oil

  • Channel the flammable gases away from the transformer to a remote area

  • Eliminate explosive gases in the transformer by injecting an inert medium (Nitrogen) into the tank and associated equipment

  • Quickly bring the transformer to a safe condition for repair after a short -circuit


CAUTION

 

During a Transformer short circuit, the TRANSFORMER PROTECTOR (TP) is activated within milliseconds by the first dynamic pressure peak of the shock wave, avoiding transformer explosions before static pressure increases.
