What is the significance of using gravel on transformer areas?
Pollux
The gravels allow the transformer oil to flow safely to the oil soak pit if the transformer oil is thrown out due to an internal fault in the transformer.Secondly,the gravels are good insulators and avoid direct contact with the earth.

How you using ref relay in transformer?
an REF relay (restricted earth fault) is used to provide ground fault protection for a transformer. Its' operation is limited by CTs starred towards the transformer (usually on the transformer bushings or in breakers used to isolate the transformer), so it will only operate for transformer related faults. Because of this, it can be set to operate very quickly.
Is transformer is essential for rectifier?
no transformer is not necessary for rectification today most of power supplies have been made without using transformer in order to reduce weight and size of power supply.for example SMPS(switch mode poqwer supply)
What is advantages-of-parallel operation of transformer?
It enables an existing transformer to be upgraded to meet an increase in load, without having to remove that transformer and replace it with a 'larger' (expressed in volt amperes) one. It provides an useful way of using up a stock of smaller transformers.
When using a step down transformer is amperage affected?
Yes, when using a step down transformer the amperage is affected.
What is the best way to clean the gravel in a fish tank without using a gravel vacuum?
you have to use your hands....
How do you reduce a 230v ac transformer to produce 140v ac?
By using step-down transformer
What is the KVA rating required of the testing transformer?

How and why is electricity transformed for different uses?
Using a transformer.
What is the significance of an electric streetcar?
The significance is that it is not using fossil fuels directly.
What are the precautions using current transformer and potential transformer?
Secondry of CT should never kept open during functioning
How input frequency to the transformer influences its physical dimension when using a step down transformer is used using as as a step-up transformer?
In general, the lower the frequency of operation, the more weight must be added to the core laminations to avoid magnetic field saturation. This increases the size and weight of the transformer as the frequency decreases.
How can geothermal be used to produce electricity?
Using a geothermal transformer
What is an explanation of the cooling of transformer?
a transformer can be cooled by using forced air-essencially attaching fans to help pull heat away.
