AnswerAccording to BS 7671:2008 Requirements for Electrical Installations, 'high voltage' is formally defined as that 'normally exceeding low voltage', where 'low voltage' is defined as "...(nominal voltages) exceeding extra-low voltage but not exceeding 1000 V a.c. (root mean square) or 1500 V d.c. between conductors, or 600 V a.c. (root mean square) or 900 V d.c. between conductors and earth".
A voltage transformer (known as a 'potential transformer' in North America) is classed as an instrument transformer. It is used to reduce the voltage across a high-voltage load to a value that can be read (usually remotely) by an ordinary a.c. voltmeter, while electrically isolating that voltmeter from the high-voltage system for the purpose of safety. It can also be used to supply an input to a protection relay.
A transformer that reduces voltage is classed as a step down transformer.
Any device that uses the generator to supply its operating voltage is electrically classed as a generator load.
Hi, The main difference is Fuel consumption. High current genertors always consumes much fuel because the load on the engine will be high. The high voltage low current generators doesn't need much fuel to run. You can understand this by comparing 1 kva and 5 kva single phase generators. For both generators voltage will be same (230v) But output current differs. So the fuel consumption also differs. But you get a high current source. Low voltage high current generators can be used for welding kind of stuffs which needs high current to do the job. If you have step down transformer then you can save the fuel.
the inductive load which is generally use in high voltage transmission line known as transformer. the transformer transform the high voltage to low voltage.

In the UK, anyone under the age of 18 is classed as a child.
Yes, if your electronic devices are not compatible with the UK's voltage of 230V, you will need a voltage converter to safely use them.

The voltage requirement for a UK USB plug is typically 230 volts.
Wales is a constituent country of the UK, so Wales can be classed as abroad from any country except the UK.
In North America the transformer outside your home is classed as a step down transformer. It steps down a higher voltage (14000) to the split house working voltage of (120/240).

It is not legal for 'civilians' to posess CS gas in the UK, as it is classed as a firearm, but it is legal for trained police officers on duty to carry it. But it shouldn't be!
