A device that decreases voltage?
Step down transformer, potentiometer or rheostats can all be used to reduce voltage.
HOW do I SELECT A STEP DOWN TRANSFORMER?
By looking to the number of turns in the Primary and Secondary Coils. "A Step down transformers are designed to reduce electrical voltage. Their primary voltage is greater than their secondary voltage. This kind of transformer "steps down" the voltage applied to it."
What do substations reduce the voltage for?
A: Substations step down the transmission voltage for distribution for the local area. The reason being that their input is in the range 0f 475 Kv trying to distribute that kind of hi voltage would be totally impractical because of insulation. So a substation step down the hi voltage to a distribution level of 16kv or so.
What are transformers designed to operate with?
to step up voltage or to step down voltage
How do transformers reduce electrical voltage?
This type of transformer is called a Step-Down transformer. All transformers have an input to output ratio. The transformers that increase voltage are called Step-up, and the transformers that protect against surges are called unity gain. The Unity gain transformer has a 1:1 ratio and provide a mechanical way to isolate a source of voltage from a load.

Why stone gravel is USED in switchyard?
Stone gravel is used in switchyards as a protective layer to prevent weed growth, erosion, and to discourage rodent activity. It also provides good drainage and helps in ensuring proper grounding of equipment in the switchyard.

Summary of the step-down transformer?
A step- down transformer is one whose secondary voltage is less than its primary voltage, it is used to reduce 'step down' the voltage applied to it. The number of coils in the primary circuit is greater that the secondary circuit. For instance, to step down 480 Voltage to 240 voltage, you need a step down transformer whose ratio of primary coils to secondary coils is 2:1.
What is step voltage?
Step voltage is a type of AC voltage where the voltage signal represents a flat step up and then a flat step down.
How is 4160 voltage made?
Well first we need to generate voltage from electrical generator. Then if voltage are below 4160 volt step up Transformer is used and if voltage are above 4160 volt step down Transformer is used. Generally voltage produced from generator are low so we need to step up voltage to higher values such as 240 kilo volt to transmit them to longer distances to reduce power losses.
What is the difference between a step down chopper and a buck converter?
Choppers are dc - dc converters, on the basis of output voltage level step down chopper is used for output voltage less than input one. A buck converter is a step down chopper with a LC filter at the output end in order to reduce the voltage ripples.
What do substations reduce the voltage for?
A: Substations step down the transmission voltage for distribution for the local area. The reason being that their input is in the range 0f 475 Kv trying to distribute that kind of hi voltage would be totally impractical because of insulation. So a substation step down the hi voltage to a distribution level of 16kv or so.
When is a step up transformer used in relationship as to when a step down transformer is used?
If the voltage needs to be increased from a lower voltage to a higher voltage a step up transformer is used. If the voltage needs to be lowered from a higher voltage to a lower voltage a step down transformer is used.
How are step up and step down transformations used in transmission of electric current from electric company to homes?
(This is what my teacher said, I wrote this down in my notes) The answer is, Step-up Transformers are used to increase the voltage of an electric current before it is sent out over transmission lines from the electric company. Step-down transformers are used to reduce the voltage of current from high-voltage transmission lines before it enters homes and businesses. Some devices, such as televisions, contain step-up transformers that increase the voltage once again.
