What electrical problem in a car can cause the stator of an alternator to be burned?

Since I have bought my car i replaced my alternator three times. When i bought the car the alternator i believe was bad so i changed it. A stock one was put back in it. that failed and i thought it was because of my audio system. i replaced it again with a 200 amp alternator and I was told that the car burned up the stator. i have replaced it again and will be going to an electrician but if anyone know the problem that is causing this it could save me a lot of money from taking it somewhere and getting charged tons of money. By the way its a 88 Acura Legend.
