Well, I am not sure about "specifics" for that particular hazard, but NFPA 72 outlines the applications and use for all fire detection and alarm equipment.
NFPA 850 is the "Recommended Practice for
Fire Protection for Electric Generating Plants and High Voltage Direct Current"
I would think I would start by at least including basic smoke detection with either spot or projected beam smoke detection. I have used the beam detectors in large switch rooms before. They seem to work well because they can cover such a large area. We have done a number of smaller "enclosed" stations with just a few spot photoelectric type smoke detectors.
