Hi,
First understand one thing seriously!! The transformer only can be rated in KVA.
Bcoz, its power factor not depends on the load connected.
No because the load is 638 VA which is too much for the transformer.
The secondary current is determined by the load. So, divide the secondary voltage by the load impedance.
Yes, when using a step down transformer the amperage is affected.
the difference between a step up transformer and a step down transformer is that, in a tsep up transformer, the voltage secondary is greater than the primary side but in a step down transformer, the voltage secondary is lesser than the primary side
A major internal short circuit has been known to burst the tank of a transformer; but it can apply to any transformer -not just a 'step-down' type.
No because the load is 638 VA which is too much for the transformer.
Transformer is a static electrical device used to step up or step down the voltage with the help of primary and secondary windings.
The secondary current is determined by the load. So, divide the secondary voltage by the load impedance.
No. A step-down transformer's secondary voltage is lower than its primary voltage. The secondary current is determined by the load, and this causes a higher current in the primary winding.
A transformer is used to step up or step down a Voltage supply.
Injecting power into the higher voltage winding of a transformer will make it act as a step down transformer; injecting power into the lower voltage winding will make it act as a step up transformer. A transformer can be used both ways.
Yes, when using a step down transformer the amperage is affected.
Any continuous load shouldn't exceed the rated capacity of the transformer, expressed in volt amperes.
You can go to ebay.com. Then sign up for an account and search for "step down transformer."
If by 'loss current' (?) you mean the 'copper losses', then there is no practical way of doing so without reducing the load current. Perhaps you should explain what you understand 'loss current', in the context of a step-down transformer, to mean?

Transformer function is either to step-up or down the voltage. There is nothing like an ordinary transformer.
