The TRANSFORMER PROTECTOR (TP), a passive mechanical system, is the sole proven solution to prevent transformer explosion. It is a Fast Depressurization System, as defined in Recommendations 850 of the National Fire Protection Association (NFPA).

With its € 15 million Product Liability Insurance, never used so far thanks to the TP performance, the TP has been tested, operated on transformers having internal short-circuit and has over 3,200 TP installed in over 200 end-users in more than 80 countries. All renowned brand transformer brands have installed several TP installed on their transformers.

The TP can be installed on existing and new transformers from 0.1 to 1,000 MVA and above. The transformer is never machined, and always existing manholes are used to perform the installation.

The TP:

• Depressurizes tanks within milliseconds
• Channels flammable gases far away from the transformer to a remote area, allowing the maintenance team to inspect the transformer without hazard risk
• Quickly brings the transformer to a safe condition for repair after a short-circuit
