a current flow close to a magnetic source it influence the sources hall effect is a disturbed signal as a function of speed.
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879
Current transformer is a device used to measure the flow of current through a power system and the measured current is inputted to a protective relay system. It is used to detect system malfunction. Current transducer is a device used to measure AC and DC current based on the halt-effect technology.
A transformer will convert the power to a different voltage, higher or lower depending on the requirement, while wasting very little of the power.
Hall Effect
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.
moct is device measure the current by means of faraday's effect..
Short circuit current will increase a lot.

A hall current sensor produces voltage by means of the "hall effect". It is used in automobile applications such as wheel speed sensors, tachometers, speedometers and ignition.
A transformer will convert the power to a different voltage, higher or lower depending on the requirement, while wasting very little of the power.
The Hall effect was discovered by Edwin Hall, and references the difference in electrical current when exposed to a magnetic field. One can find out more about the Hall effect by consulting a physics textbook or physics teacher or professor.

why does have to short-circuit secondary wire of current transformer ?
the short ckt curent will be very high.
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.
