What is the rules as per transformer work?
Transformer works on the principle of Electromagnetic induction.
How is current controlled in welding transformer?
in welding machine, the transformer used is basically a current transforrmer. so by changing the tap of secondary side of transformer, we can increase or decrease the current in the transformer.
Difference between potential transformer and current trasnformer?
The difference between current transformer and potential transformer is that the secondary of a current transformer can not be open circuited while under service whereas that of the potential transformer an be open circuited without any damage to the transformer.
What is zero current transformer?
It is a transformer with No load attach to it.
What is the reason for using a neutral current transformer on a transformer?
A current transformer is primarily used at the neutral point of a transformer for earth fault protection. A neutral current transformer will measure any ground fault current which will essentially flow from the star point of the transformer. A fault-detection device other devices is connected to the current transformer and, if the fault current exceeds a certain trigger value, the fault-detection device will give a trip command to an earth-fault relay to disconnect the supply of electricity to the transformer.
Fundamental principle of current transducer?
The basic principle of current transformer is same as that of the power transformer. Like the power transformer current transformer also contains a primary and a secondary winding. Whenever an alternating current flows through the primary winding alternating magnetic flux is produced, which then induces alternating current in the secondary winding. In case of current transformers the load impedance or "burden" is very small. Therefore the current transformer operates under short circuit conditions. Also the current in the secondary winding does not depend load impedance but depends on the current flowing in the primary winding.

Why is it impossible to use a transformer on a direct current where the current is steady at all times?
alternating current has two halfs in one cycle.In one half it flows in one direction and in other half it flows in opposite direction.due to fluctuations ,alternating current has ability to produce phenomenon of mutual induction. and mutual induction is the basic principle on which a transformer works while direct current cannot produce phenomenon of mutual induction.thats why a transformer is not used on a direct current

What is the principle of transformer working Explain the working principle of transformer on no load?
Transformer is a static electrical device used to step up or step down the voltage with the help of primary and secondary windings.

Is it possible to use optic fiber as a core in the transformer?
No. Transformers operate on the principle of conversion of electric current to and from magnetism. Optic fiber is not ferromagnetic, nor is it conductive.
Difference between and rcd and an isolating transformer?
An rcd is a device designed to limit duration of electrical shock by disconnecting the circuit when a fault is detected. An isolation transformer is a 1 to 1 (same voltage and current in and out) transformer that keeps one part of an electrical system physically unconnected to another part of the system. It does this by using the principle of a transformer to allow current flow, without actually connecting the load to the source wires.
