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.
What will happen to frequency of current when voltage is changed using a step up or step down transformer?
Frequency does not change when you use a step-up or step-down transformer. Only current and voltage is changed.
Why are stripes of iron plates joined instead of using a single block of iron core in a transformer?
To reduce heat generated and eddy current losses in transformer's core during operation.
What formula would be used to convert at current transformer rating at 60Hz to 25Hz?
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.
Why electricity does not flow through iron core of transformer?
It does. We call this current, or currents, 'eddy currents', and they are minimised by using laminated cores.
How do you step down current?
by using current transformer
What is current trandformers?
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.
How do you test a current transformer using a digital signal processor?
You don't.

What are the precautions using current transformer and potential transformer?
Secondry of CT should never kept open during functioning

Can you amplify the AC in your data center using an AC transformer and how?
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.

Direct current 12v to 10v to increase amps?
using a step-up transformer. ****warning***** will stress a power supply

More the transformer impedance less the fault current... so is a high value of transformer impedance good for it?
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.

What are the Causes of phase angle error and ratio error at Current Transformers?
RATIO ERROR The secondary current is less than the expected value. The secondary is less in magnitude. This diffence is known as ratio error. PHASE ERROR The angle between the expected and actual secondary current is known as phase error.
