What is meant by rated voltage rated current and rated power of a transformer?
The ratings state the limits on voltage and current for operating the transformer at full load. The rated voltage times the rated current gives the rated VA of the transformer. Transormers are not usually rated directly for power because this depends on the power factor of the load applied.
What is rated voltage and current in transformers and how to calculate them if given 50k VA?
Rated voltage is the voltage at primary side. Rated current can be found from the equation, Rated Current= Output KVA / Output rated voltage
Define rated impulse voltage?
Simply, the voltage which is withstand by the test object as an impulse is called as rated impulse voltage.
What voltage is the kettle?
It depends where you bought it. In North America, its rated voltage will be 120 V whereas, in Europe, its rated voltage will be 230 V.
How do you calculate voltage regulation of 33kv and 11kv distributions?
Regulation =(Obtained voltage per phase - rated voltage per phase)/rated voltage per phase *100
What is withstand voltage?
It is the rated test voltage that will not cause insulation breakdown.
What is meant by voltage source inverter what it does?
no
Why the rating of lightning arrestor is less than its rated voltage eg for 400 kv system it is 360?
The MAXIMUM rated voltage is the voltage at which the electricity would arc across the insulators The usage voltage is lower than the rated voltage (usually somewhere around 80% The lightning arrestor voltage is in between. It will not pass current at the usage voltage, but will pass current when the voltage exceeds the arrestor threshhold
How many amps should a low voltage fuse be rated for?
A low voltage fuse should be rated for 30 amps.
Can use rectifier in high voltage?
Sure, as long as it's rated for that voltage.
Why is that when an electric bulb stay just as its bright when connected to a parallel circuit?
To operate at its rated power, a lamp must be subject to its rated voltage (the supply voltage). As each branch of a parallel circuit is subject to the same voltage (the supply voltage), each lamp will operate at its rated power.
How do you change operating voltage of metal halide lamp from 240 to 120?
The lamp needs to be rated for the voltage applied to it. The fixture in which the lamp is installed also needs to be rated for the voltage. So, it is not a matter of changing the lamp, it is a matter of having the fixture and lamp that are properly rated for the voltage that you are applying to it.
