SERGI TRANSFORMER PROTECTOR, a French company founded in 1955 has expertise of more than 50 years in the field of transformer protection.

In 1995, SERGI TP launched an intensive research program to understand the physical phenomena of transformer explosions. As a result, SERGI TP has created, designed and manufactured the TRANSFORMER PROTECTOR (TP), the only proven solution against transformer explosions.

The TP is a passive mechanical system which can be adapted to any oil filled transformer above 1MVA to protect against explosion. It is now recommended by the NFPA standard 850.

When a short circuit occurs in the transformer, the TP is activated within milliseconds by the first dynamic pressure peak generated by the electrical arc, avoiding transformer explosion by preventing static pressure from increasing.

SERGI TP has performed 62 tests in :
Électricité de France (EDF) High Voltage Laboratory in 2002 (28 tests) :
CEPEL Independent High voltage Laboratory in 2004 (34 tests).
During all these tests, the TP always succeeded in preventing the transformer from exploding.
