Narrative:

During IOE with the first officer on final approach received a gen 2 caution message; briefly considered continuing but reconsidered and ran checklist. I misidentified gen 1 as the faulty gen and attempted reset; as a result the air driven generator deployed. Subsequently correctly identified and reset gen 2. Continued to landing uneventfully. I as the pm made the mistake and was the cause of the misidentification and deployment of the air driven generator.I was very involved in giving instructions to my student for the approach and landing and allowed myself to be distracted enough that I misread the caution as a gen 1 caution instead of a gen 2. Completely my mistake; I should have probably either continued at that point or conducted a go-around to assure adequate attention and fewer distractions which would have prevented a simple situation from becoming a more serious one.
