I have "Algeo.apk" in my galaxy tab, it is a wonderful application in small scale.

Condition of rotor is not important in this case. When the frequency of power supply drops close to zero without any voltage reduction, this case is same that you connect an ac motor to the dc power supply. Generally reduction of motor internal inductance due to frequency drop (Xl=2*pi*f) can be...

In ac regime we can say: 1-Induce forces always are atractive when phase difference between two faulted phase is zero. 2-Induce forces always are impulsive when phase difference between two faulted phase is 180 degree. 3-generally the average of time variable induce force is related to...

i don't have addition description.

Kirchhoff’s laws provide a set of procedures for determining voltages and currents in a circuit. Other methods, such as Maxwell’s mesh equations and network analysis techniques, are available to solve the same types of problems and, in many cases, are easier to use when the circuits are...

Behavior of battery in parallel or series connection can be explain easily by simulation of it with an constant emf series with a variable resistor which the variation is related to its age and weak or strong conditions. When two batteries with different internal resistance are connected in...

According to some definitions, the primary side of a transformer is the side that connected to power supply. Please specify active power supply or reactive power supply. Please note to attached page, as you know, illustrated situation is possible in power system, which side of transformer (1 or...

Please note to fundamental transformer equation as attached page. As you see, the magnetizing inductance (L1h = w1/w1.M) which related to magnetizing flux and current is related to primary and secondary mutual inductance. Therefore transformer magnetizing current effects is shared between...

Dear cabraham, Which your reference book agree your idea (magnetizing current exist just in one side of loaded transformer) clearly. As you say, you know transformer inrush current. Whether it exists in primary side of transformer exclusively? I say No! All phenomena which related to linkage...

Fact is simple, but finding it is difficult. Please go back to basic and try to answer my questions, I think you don't like to leave your traditional belief.

Dear Cabraham, What is primary or secondary side in a transformer? How can you specify the primary and secondary side of a power transformer in one transmission system which the direction flow of energy can be variable in it? Whether active power direction can determine the primary/secondary...

I think, the general education level of electrical engineering is low in worldwide among U.S and Europe now. Unfortunately your conceptual understanding of basic concepts is very weak. I think it is related to explosion of information (internet) and huge relevancy to it.

It is not related to generator grounding or transformer primary and secondary coupling terms, in this case we face to distributed capacitance of transformer winding which close to core body (which usually is grounded). Indeed during mentioned measuring we measure difference voltage of that...

Please refer to attached page. Thank you very much my dear friend.
