DESCRIPTION

Principles
The TRANSFORMER PROTECTOR is a concept that can be applied to all transformers from 0.1MVA [8]. It enables to:
•depressurise tanks within milliseconds;
•avoid contact between air (oxygen) and the evacuated explosive gases;
•separate gases from the oil;
•channel the gases far from the transformer environment to a
remote area;
•eliminate explosive gases for people security by making use of nitrogen injection;
•quickly secure the transformer for a safe intervention.

The TRANSFORMER PROTECTOR is a passive mechanical system, which can only be activated by the level of transformer tank internal pressure reached during short-circuits. The TRANSFORMER PROTECTOR has therefore a very high reliability, false activation is impossible.
