Under three phase balanced system

suppose there is a balanced condition in a power system, then current in the neutral conductor is zero. So i want to know that how our...

Why only we use 3 phase why not 5 phase

i 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...

Why only we use 3 phase why not 5 phase

Using 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...

Can Air Act As "Ground" For Electrical Circuits?

Let me tell you. In the airplenes , grounding is provided with the body of the airplane. Since the body of the airplane is so immence,...

Under three phase balanced system

Under three phase balanced system, current in the neutral conductor is supposed to be zero. So if neutral is not carrying the current then how the...

Why does ceiling fan rotate in anticlockwise direction and table fan in clockwise direction?

We can change the direction of rotation of table fan since it incorporates shaded pole induction motor. If we change the shaded pole from left extreme...

What is the difference between machine and device ?

Seems like u never worked on computers. Thats why u are indulging another person. Nevertheless let me tell u...comupter is not a machine...further u know...

Why does ceiling fan rotate in anticlockwise direction and table fan in clockwise direction?

Why does the ceiling fan rotate in anticlockwise direction and table fan in clockwise direction?Answer: The direction a fan spins, whether it's a ceiling fan or...

What is the difference between machine and device ?

lalThen why is a computer called machine? 😁 There isn't any electromechanical energy conversion as in motors and generators in a computer! An IC engine is...

What is the difference between machine and device ?

A machines is a device capable of continous electrmechanical energy conversion like motors , generators. That's why , according to this definition, transformers are not considered....

Why excitation provided to alternator is DC?

Suppose you have applied a ac supply to an alternator field. Now during first half cycle, rotor will try to rotate in one direction. Now when...

Why India uses power supplies of 50HZ standard ?

higher the frequency , higher will be the transmission line reactance, ans you know that maximum power transfer capability is inversly prportional to the line reactance....

How to complete circuit of 1-phase supply under balanced conditions?

In our houses, we have 1-phase supply whose return path is neutral. Now suppose loads get balanced on all the three phases of the 3 phase...

Is Power Transferred To Consumers Or Energy?

ok thanks..i got it 😀

Is Power Transferred To Consumers Or Energy?

So bottom line is that energy is transferred nor power to consumers..??

Is Power Transferred To Consumers Or Energy?

First Power Came Into picture, then Energy...Power should be what is transferred to consumers..and energy is consumption of power with time..isn't it??. So power is transferred...n...

What is the resistance between neutral and ground or earth?

I am an electrical engineer and here is my attempt at answering your question. Let me know if you understand this or have any follow-up questions.The...

Is Power Transferred To Consumers Or Energy?

Anand TamariyaIf you are talking in technical terms, at the generating side, energy is produced (strictly transformed) as defined by conqueror. Are you confused because generating....

Is Power Transferred To Consumers Or Energy?

But at the generating side, power is produced. So how could energy be transferred?. Power consumed by load with time is energy. So, finally, power is...

Is Power Transferred To Consumers Or Energy?

Is Power Transferred To Consumers Or Energy??

If DC supply is given to TRANSFORMER

Actually when dc is applied across the primary, a pulse will be there at the secondary for very short peroid but then the secondary voltage will...

Why we Stopped Using Bulbs Even It Provides Almost Unity Power Factor ??

Anand TamariyaUnity power factor is desirable for distribution systems. Efficient lighting (more luminosity/watt) is desirable for light source. Hence, move to CFL and now LED. Kee...

Applications of DC to DC converters

These Are Used In Maximum Power Point Tracking Of Solar Energy. By Using dc-dc Boost Converter, we Increase Operating Voltage Of Solar Array. And By Using...

What will happen to charges that flowing i devices once after supply switched off?

rahul69First of all I said electrons and not charges (and electrons are negatively charged), but at zero potential difference also, electrons (as well as protons) are...

Why we Stopped Using Bulbs Even It Provides Almost Unity Power Factor ??

Why we Stopped Using Bulbs Even It Provides Almost Unity Power Factor Which Is Always desired??

What Is The Phenomenon Named "Blowback" In Inductive Loads??

What will happen to charges that flowing i devices once after supply switched off?

rahul69Source cannot produce electrons, it just create a potential difference which forces the free electrons to move thus creating current. Take an analogy: Consider a setup...

Difference between ac and dc resistance?

AC resistance should NOT be confused with IMPEDANCE or REACTANCE. When AC flows through a conductor, it tends to flow towards the surface of that conductor...

Why The Generator Rating Is In kVA & Of Motor In kW??

MPPT Of Solar Energy

bioramaniA lot of India (South of Vindyas) is in the tropics. Nothing wrong though in going for the project.thank u sir...

MPPT Of Solar Energy

bioramaniIs MPPT of much use in the tropics? This is probably more relevant in cold countries in winter when the PV cells develop high voltage at...

MPPT Of Solar Energy

Is MPPT Of Solar Energy A Good Topic On Major Project Basis??
