Transformer works on the principle of Electromagnetic induction.
A transformer is an electrical device that takes electricity of one voltage and changes it into another voltage.
Transformers don't work with DC supplies - they only work on AC.
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.
A stp-down transformer steps voltage down from a high value to a low value. Transformers only work with AC.
major component of power loss in a transformer is secondary resistance.when transformer is operated under no load,no current flows through the secondary.so under no load conditions transformer has just very small megnetic losses.
transformer will work on ac
One transformer should feed several led's in parallel, but you have to work out how much current each one will take, total it up, and then get a transformer with the correct output voltage and that can supply the total current. Don't exceed the transformer max current or it may fail through overheating
The Bicepticons
yes
The working of a transformer depends on the Faraday Law of Electromagnetic Induction.
No. A transformer has to have AC, alternating current, to work. And since it's alternating, it'll have a frequency.
Its transformed into work!
Find the wire from the secondary of the transformer. If it's a step-down transformer the thicker wire is the secondary. Measure its diameter in inches and calculate its cross-section area in square inches. The current rating for transformer wire is 1000 amps per square inch, or 1.55 amps per square mm.

..the questions does not say wether the 30kVA transformer is 3 phase transformer or single phase transformer..but it is implying that a single phase welding load at 16A per phase is to be connect to it, it is assumed then that the transformer is 3 phase transformer..we assume load is rated 240V.. ..though not much details is given about the transformer voltage specs. but if is rated 3 phase 415/240V, the approx full load current per phase is given by 30KVAx1.3912=41.736A.. ..but if the transformer was rated single phase 240V say, the approx full load current FLC=30000/240V gives 125ampers.. ..if you further devide the FLC by the intended load current.. ..Recommended no of welders per for a 3 phase 415V transformer and assuming single welding sets =41.736/16=2.6..so you can connect max two welding sets to this transformer per phase,..max 6 weld sets can connect at an approx load factor of 76%.. ..for the single phase transformer, FLC/16=125/16, gives 7.8 but is also recommended not to connect more than 6 welding sets to such transformer for the same reasons..
