Energy is one of the most important resources for the development and quality of life. Therefore, protecting energy production is fundamental.
A transformer is an electrical device used to increase or decrease the current voltage. These processors make sure that the electricity is ready to be distributed on the network for which it is intended. The Transformers generally consist of different chambers/cacards containing more or less flammable fluids (coolant, oils).
The most frequently encountered risks:
Choose the best fire protection for your power plant or electrical distribution equipment when an electric arc or Overheating develops inside a transformer, gas releases, oil vaporization, occur, and if the overheating is more important than the passive protections can withstand, a fire may occur (presence of flammable oil and coolant).
The most effective protection in this type of scenario is the powder extinction. Especially if the transformer is in a confined environment.
Water mist (or even additivated water mist) can be considered an alternative: when water and oil (non-miscible liquids) are agitated together and one of the liquids is dispersed in the other, this causes an effect of Cooling on the surface of the oil and prevents the release of flammable vapors.
