AC change path called frequency having 0 to 360 degree and
all alternator phase sequence design at 120 degree
differences ie 0/360 - 120 - 240 Degree universal in
3 phase sequence called R Y B

Answer / karun

We can transfer power 2 or 3 or 4 phase but we know that
actually power generation is done in 3 phase it is economic.
If we want to transfer 4phase we should generate power from
different generators.
and i agree this answer

Answer / simon

There is a device namely alternator/Genrator (big size) which genrates 3 Phase supply i.e R,Y,B in max of 11000v or 11kv only in India. Hense the multiple will b always in 3.

I just purchased a 4 position cam switch to be used to operate a 3-speed blower motor. The motor is a 10 amp motor and has 3 wires that are used to control speed. The cam switch was rated at 660V 20 amps but when I received it, I noticed that it has AC-15 operational current rating (Ie) of 4/5 amps. If I am reading the label correctly. the 4/5 amps is related to 440v/220V (Ue). Other ratings are AC-3: 5.5A, AC2: 7.5A and AC-4: 1.5A. My questions are 1) Is it safe to use this switch with the motor I have 2) what is the difference between the 20 amp Ith ratting and the Ie operational ratings?

some practicle study shows that the reactive power at the receiving end is not equal to the reactive power at the sending end.But according to theory the reactive power is exchanged by different parts of the network – capacitors and reactors permanently, but is never consumed or produced. Then Where that reacrtive power loss occuring?is there any formula to calculate reactive power loss?
