Is odd harmonics present in push pull amplifier?
Odd harmonics are theoretically the only harmonics that are produced by a push-pull amplifier, and even the level of odd harmonics should be very low.
What is meant by histerisis?
what is meant by histerisis in terms of Elctrical Machines?
Why excitation transformer vector group is only DY5?
This is basically to reduce the harmonics injected back in the grid which are generated because of the controller rectifier circuit (Thyristor Bridge - B6C) after the transformer secondary.
What are disadvantages of harmonics?
harmonics increase heating of motors ,transformers and capacitors .Power system protecting relays may operate falsly, meters give inaccurate readings,interference with telephone lines may also occur. Moreover resonance due to harmonics also causes problems
Does capacitor banks produce harmonics?
No, capacitor banks reduce harmonics. They act like a low pass filter. They also raise voltage by compensating for inductance and bringing the power factor back closer to 1. Capacitor banks in the power system can cause transients when randomly closed - many utilities use zero voltage closing equipment, or inductors to counteract this short time harmonic problem.
What is the need for harmonics compensation in electrical circuit?
1)to reduce the power loss. 2)to avoid the noise.
Will a car start with battery polarity reversed?
No, and it may have caused major damage to the elctrical system.No, and it may have caused major damage to the elctrical system.
What guitar has the best harmonics?
There are no best harmonics.
When did Sigma Harmonics happen?
Sigma Harmonics happened in 2008.
When was Psy-Harmonics created?
Psy-Harmonics was created in 1993.
Is odd harmonics present in push pull amplifier?
Odd harmonics are theoretically the only harmonics that are produced by a push-pull amplifier, and even the level of odd harmonics should be very low.
Chorded windings are used in induction motors because?
Its the simplest way to reduce the harmonic induction torque(i.e. by weakening the stator winding mmf harmonics)
What is the term for overtones that are multiples of the fundamental frequency?
They're called "harmonics".
When was Sigma Harmonics created?
Sigma Harmonics was created on 2008-08-21.
What are harmonics in power distribution system?
Harmonics are a multiple of the fundamental frequency. If the power frequency is 60Hz, harmonics occur at 120Hz, 180Hz, 240Hz, etc.
What is elctrical?
Any thing belongs to electricity is electrical.
What is the part on an atom that carries no elctrical charge?
neutron
