A fire occurred in a ceiling fan in one of our room. We found the fire suddenly developed at the running condition of the fan around the capacitor area. Quickly the power breaker made off & fire extinguisher used to extinguish the fire.

After dismantling the fan, I checked the fan, the capacitor found OK, just burnt on the surface. Basically the plastic cone shaped cover burnt a lot.

What would I suspect? What can be the reason of that fire?

The source volage, according to design is 220-230 VAC, and at that moment the supply voltage was 230 VAC .

. Give your valuable suggest so that we can prevent that type of accident in future.

Curious where you live. On one of your other post, you say Ballast and light burned up,
On this post, you say fan burned up, and 230 volts to neutral, and 190 volts.
I think you have very serious electrical problem. Not necessarily Expensive to correct.
I would measure voltage Coming from meter, Check Panel Voltages, then check circuit voltages. Low voltage can burn up and destroy motors, pumps, lights, compressors. Its Just Dangerous.
Can you give more info? I live in US, never heard of 230 volt ceiling fan.
Would be more efficient at 230, just never heard of.

I too am curious where you live. Also, what make is the fan?

American made ceiling fans - Ceiling Fans N More (http://www.ceiling-fans-n-more.com/ceiling-fan-capacitors.php)

From dewanjee:

Well, I live in Bangladesh. Does that make any sense to you?
In our country, the single phase supply voltage is rated as 220-230 VAC, 50 Hz.

To erase your confusion against different supply voltage against two different mail, let me explain. Actually, in one premises, two factories are there. One uses Government supplied power source which has fluctuation, unreliable & can come down to 190 VAC.The other factory, an ASU plant use their own generated power, so much reliable, steady, 230 VAC (p-n).

Now, light burnt in the earlier factory having low voltage problem & also having voltage fluctuation.
The fan burnt against the source supplied from the stady source.

So, Suggest how I can conclude? For the fluctuating source, can we use a voltage stabilizer (for office lighting, 5 storied buliding)? Would that be feasible?
We are looking for a failsafe solution against those type of fire hazards.

In case of lighting fire, eletromagnetic ballast was used. Up to what % of recommended voltage is safe to use against a ballast? We are confused as electronic ballast also failed though low voltage was there.

Do you need to know anything more?

Thanks,

It definitely sounds like a problem with the supplies, not the fan and light.

I don't know much about this, TK?

Can the ASU plant handle load of other.
Didn't realize problems over there, and seem compounding
Out of the about 60 plants, 25 are down due to Mechanical or other problems, along with your generated power of 3000 Megawatts and 4500 Megawatts Demand, Its no wonder the riots over power and electricity. 6 Kids died in one protest. Don't see easy answer,
Will continue looking. I understand Electricity shut off daily
