It's called a 'distribution transformer', as opposed to a 'power transformer' which is used in the transmission and primary-distribution electrical systems.

Which transformer raises the voltage high and lower the current for transmission?
A step-up transformer.
What type of device is used to increase or decrease the voltage of an electric current?
The device used to increase or decrease the voltage of an electric circuit is a step up transformer or a step down transformer respectively. A Variable Resistor
How demagnetize an electric motor?
A transformer winding only produces a magnetic field when current flows through it. Switch the current off, and the magnetic field disappears. You do not need to 'demagnetise' a transformer winding.
What is the function of a summation current transformer?
Current transformers are used to measure electric currents. When current in a circuit is too high to directly apply to measuring instruments, a current transformer produces a reduced current accurately proportional to the current in the circuit, which can be conveniently connected to measuring and recording instruments.
What is ct coil?
It means Current Transformer is used for measurement of electric currents, together with voltage transformers
Which transformer raises the voltage high and lower the current for transmission?
A step-up transformer.
Why do electric company generators produce alternating current?
Because alternating current can be run through a transformer to step up or down the voltage. High voltage current incurs lower losses in transmission.
What type of device is used to increase or decrease the voltage of an electric current?
The device used to increase or decrease the voltage of an electric circuit is a step up transformer or a step down transformer respectively. A Variable Resistor
Is current transformer is a distribution transformer?
In transmission lines there is a massive current, we use CT to make this current measurable i.e. it steps down the current but DT is used to step down the voltage
What is magneto optic current transformer?
moct is device measure the current by means of faraday's effect..
What are examples of an electric current?
Transmission Lines are an example of electic current
Is transformer side interchangeable?
yes,we can change the transformer side in transmission line as use of high current or high voltage in output.
What are some examples of an electric current?
Transmission Lines are an example of electic current
How demagnetize an electric motor?
A transformer winding only produces a magnetic field when current flows through it. Switch the current off, and the magnetic field disappears. You do not need to 'demagnetise' a transformer winding.
What do moving electrical charges create?
-- Electric charge that's moving is the definition of electric current.-- It creates a magnetic field in its neighborhood.
