CAUTION

 

SERGI does not recommend to limit the amount of conventional mechanical or electrical protection devices when the TRANSFORMER PROTECTOR is used.

 

    Description
     Principles

     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.

     The TP is a passive mechanical system, which can only be activated by the dynamic pressure peak generated during short
     circuits.

     The TP has proven its high reliability and there have been no reported cases of spurious operation.

TP CIVIL LIABILITY INSURANCE

 

The SERGI Insurance Company covers the TP in case of malfunction during its whole operational life. The current coverage, Euro 3 Millions, increases yearly because the TP never failed. The TP coverage is often better than transformer manufacturer's.
