Current overload from whatever circuit draws current from the transformer? Proper fusing of its supply might protect a transformer from this cause. Or it could have developed a shorted turn fault because the insulation on a winding got old and perished? Or maybe the transformer got damaged if the appliance it is mounted in was dropped?
What else can I help you with?
How current transformer get burn when open circuit happens?
Because of fire
If you have a 1000kva transformer than can you work on that transformer?
No. From what you're saying you're taking the input to the 2kV transformer in a microwave and replacing it with a 1MW input. The transformer will burn in milliseconds of power. <<>> The installation and maintenance of a 1000 KVA transformer can be worked on in a de energized state. To do so live could be extremely dangerous at any voltage.
What happened if you connect 230V to secondary of transformer whose voltage rating is 230V to 18V?
if you drove the 18V winding with 230V the transformer would burn out, if it didn't catch fire first
Why the windings burn when transformer is operated in DC?
Transformers are not intended to be operated in DC. DC does not provide the continuously fluctuating current that a transformer requires in order to function. On DC, a transformer will act as a transient mode inductor, and settle out to a high current state, destroying itself.
Why don't we supply to DC to the transformer?
When we give d.c supply to a transformer the primary winding will burn because constent flux will be will be produced which doesnt link with secondary so max current will circulate on primary winding only

Why does the primary side of a step down transformer burn out and not the secondary of a 480V to 240V transformer?
Sounds like the wrong size fuse protection was used. The transformer should be protected to its kva capacity.
Why does your 24 volts transformer get hot then burn out?
A transformer gets hot if it is run at excessive voltage or excessive current. Either of those two would cause it to overheat. <<>> It sounds like the load on the secondary is greater that what the transformer can supply. A transformer is wound for a specific amperage output at a specific voltage. This is stated on the transformer as a VA or in larger transformers as KVA. If you divide the 24 volts into the VA listed on the transformer you will get the maximum amperage value of the transformer. If the device that you are connecting to the transformer is greater in amperage draw that what the transformer can supply, this will cause the heating effect and if left connected eventually burn the transformer out. A fuse should be installed in the secondary 24 volt output, rated at the maximum output of the transformer. This will limit the transformer to its manufacturer's recommended current output.
Can you hook up a 250 volt 2.5 amp plug to a 1500 watt transformer?
What has to be taken into account is what the primary and secondary voltages of the transformer are. The second thing to consider is whether the transformer is a step up or step down transformer. Just putting 250 volts on a transformer could burn the windings if the transformer is not the correct voltage.
What happens when an alternating potential difference is applied across a primary coil of a transformer?
burn or burst

How transformer output connections get burn?
Poor connections could result in arcing; the transformer could be overloaded as well, resulting in more current flowing through them than designed.
What causes transformers to burn up?
the heat formed in the core due to the "eddy currents" burns a transformer
Can you burn out a 750mA transformer in a 20a circuit?
If you know what you're doing, you can probably accomplish that in a 1A circuit.
What happened if you connect 230V to secondary of transformer whose voltage rating is 230V to 18V?
if you drove the 18V winding with 230V the transformer would burn out, if it didn't catch fire first
Why does the television gets burn when you plug it in 220 transformer?
Could be because the television should run on 110 v.
What will happen to the transformer if the rated voltage is applied to the winding during short circuit test?
the winding would burn....
