what is the difference between pure and impure power "ROHIT"

Answer / gtmanikandan

i can easily understand mr Vineeth answer, thanking for
vineeth

Answer / vineeth

In my point of view,it may be due to the construction and
speed of the generator.We know that "f=NP/120".According to
this equation frequency is directly propotional to the
product of speed and the number of poles.For example,
speed,N=1500rpm and number of poles,P=4,then the
frequency,f=50Hz.If the speed,N=1800rpm,then the
frequency,f=60Hz.

Answer / thuranga

We all know that as the frequency is increased the conductor
size must be increased, In INDIA (being a economically
backward country when compared to US) found operating at
50hz is more economical than that of the 60Hz.and coming to
US it has a very high quality of power because the
investment for the power is also high which it can afford.

So my friends it is only for the Economical reason why India
is using 50Hz and Us with 60Hz frequency,and not any other
reason.So only all the equipment in India designed to work
at 50Hz to make the equipment economical for a common man.

Thank u

Answer / subrat kumar das

it used accordingly to the standerd of the power generation.

Answer / rohit chourey

I Think in Us they are using Pure Power coz they have
surplus amount of electricity n tht's why for gaining pure
power they use 60Hz frequency.

Answer / chandan

machine are rating 4 this frequency

i have one source transformer with the capacity of 50KVA, connected with two loads 10kw and second one is 15kw.. how can i calculate first load in KVA and second one in KVA .. because Kva rating, power factor rating of of transformer is different from the load… there must be some way to calculate load KVA rating and power factor….
