Yesterday in our office room, fire occurred in one side of a double tube light set. Fire initiated from the ballast & starter component. Related circuit breaker didn't trip & the other light was still live when the fire took place. My findings were, no loose connections, ballast connection port fully damaged, starter & light base damaged.
Now this the second time fire took place in a tube set. As a corrective action, we put few electronic ballast instead of electromagnetic ballast/starter combination, unfortunately few of those ballast explored with huge sound, no fire took place.
Just to share, we have voltage fluctuation, and sometime single phase voltage come down to 190 V also. How low voltage can act?
My ultimate question is, give a best solution to replace those electromagnetic ballast to avoid anymore fire hazard. And what else precautions we can take for the time being. Is a voltage stabilizer can act as a good solution & then usage of elctronic ballast ?
. Help me out of this situation.
Thanks,

Thanks Rovertva for you quick answer. Sorry not to mention the expected source voltage; that would be 220-230 VAC phase to neutral.
Well, no problem so far occurred in other devices like Computer, refrigerators.
So, in our case the problem is low voltage, around 20%.
So, Suggest me what should I do to prevent any more fire hazard.
Thanks again for your support
