Why only we use 3 phase why not 5 phase
pinankYes you can say it in a way. But if u are wondering why a 5 phase system is not used in generators, the main reason...

Why only we use 3 phase why not 5 phase
pinankNo in a 5 phase system you won't get the symmetry between the phases. Let's say there are 5 phases A,B C D E. Now the...

Why only we use 3 phase why not 5 phase
pinankWe know nature always follows a balanced system. Now consider a system with more than 3 phases. The angular displacement between two phases will not be...

Why only we use 3 phase why not 5 phase
Void RunnerYou can use as many phases as you want. The main concerns are costs and heat generation, at a certain point the gains provided aren't...

Saandeep SreerambatlaI think you have got me wrong here. Consider a 3 phase system which has phase angle of 120 degrees and which are in series...

Why only we use 3 phase why not 5 phase
naman2511i am talking about the power gain... single phase power is VIcos(phi) while that of three phase system, power is sqrt(3)*V*I*cos(phi) where V and I are...

Rotor angle change in alternators
Dhayalan.Swhen will the rotor angle change in large alternators???It changes when there is a change in load or fluctuation or any type of fault. I will...

Why only we use 3 phase why not 5 phase
naman2511Using 2-phase system will provide you gain of around 1.4 time of 1-phase system. Using a 3- phase system will provide you gain of 1.57 times...

Traction system of India?
Saandeep SreerambatlaIn India we generally use, 1500 V DC , 25kV AC 50Hz supply all over. There are cases where we are using multiple supplies in...

Need a idea for current equalisation?
A.V.RamaniThat only wastes power. Is there any reason to do that? In the house we have so many loads all running from the same 220 V...

Need a idea for current equalisation?
A.V.RamaniAkilesh, edo kozhappam kanunnundu. There is some confusion. Let us say you have four loads with these currents: L1- 5 amps, L2- 4 amps, L3- 3...

Need a idea for current equalisation?
A.V.RamaniI am assuming that even if the supplies are different the loads all have a common ground. Otherwise it is equivalent to having four unrelated circuits....

Need a idea for current equalisation?
A.V.RamaniAkhilesh, If you have a single voltage source and loads with unspecified variations, it is not possible to have all load currents equal because of Ohm's...
