ya mom u stupid noob.
what do u expect from a sentace that doesnt make sense. ure metal.
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.
Frequency does not change when you use a step-up or step-down transformer. Only current and voltage is changed.
To reduce heat generated and eddy current losses in transformer's core during operation.
I don't understand your question. Are you asking how to convert from 60hz to 25hz using a transformer? That cannot be done. Frequency in = frequency out.
It does. We call this current, or currents, 'eddy currents', and they are minimised by using laminated cores.
by using current transformer
I believe you meant transformer. If so it is a transformer used in high voltage circuits to reduce the current to a safer measurable value. It can be used as a direct input to a metering or protective relay to covert high currents to a lower value. It is used in AC circuits and typically encircles the conductor(s) it is monitoring, then works by using the expanding/ collapsing field which is the theory of induction used in transformer operation. It is the primary side of a "transformer" which only works when there is current flowing through it.
It is a multimeter with a clamp on facility to measure current using it as a current transformer.
You don't.

Yes, the AC current can be amplified by using Step-down transformers, but one problem is the AC voltage will decrease with Step-down transformer.

using a step-up transformer. ****warning***** will stress a power supply
It depends a lot on the application, i would go with low impedance transformers if am using the transformers for distribution as it will really increase the the maximum fault current. If am using the transformers as step up specially for generators or to charge capacitors, using a high impedance transformer is a good idea as it will decrease the inrush current of the system. you have to see your application and decide what fit that best.
