Can foam system be used for fire protection in case of electrical transformers ?
You could use a high expansion foam system to protect an electrical transformer, but it will require to enclose the transformer within walls/dike 1.1 times it's height in order to hold the foam for an amount of time. I do not know how effective a foam system will be, but certainly it will be more expensive than using a water spray system.
If the scenario is an oil spill from one of the transformers, the simplest and cheapest solution is having the fire brigade use handline foam proportioners connected to the fire hoses.
