Harmonics are the result of the current waveform being distorted by a non-linear load, such as a computer power supply or a motor control drive (VFD). In a commercial setting (which is usually 3-phase), harmonics cause unwanted current to flow which does no useful work, yet must be accounted for when sizing conductors, Transformers, etc. Harmonics are certainly not limited to 3-phase systems, however. Any non-linear load, even single-phase, causes harmonics. Your computer, television, and microwave oven probably create harmonics. In a residential setting though, there are not enough cumulative harmonic currents to worry about. Unless you have 50 computers at your house...
What else can I help you with?
Why is the Neutral fundamental in a three phase Y-Y Transformer connection?
Suppression of harmonics
What are the three types of phase on its final phase?
single phase, double phase & three phase
What is the difference between a one phase and a three phase motor. And if a three phase motor is given a single phase supply will it run or not?
The difference between a single phase and a three phase motor is the amount of power conductors that feed the device. As to the other part of the question a three phase motor will not start or run on single phase. The phase angles on three phase are 120 degrees apart on a single phase system they are 180 degrees apart.
Is there a difference between three phase and single phase electrical supplies?
Yes, there a difference between three phase and single phase electrical supply services.
Why three phase meter is better than single phase meter?
A three-phase meter can be used for single phase while the reverse is not the case.
Why the need of harmonics in single phase transformer?
Harmonics are really not needed in single phase transformers.
Why is the Neutral fundamental in a three phase Y-Y Transformer connection?
Suppression of harmonics
Single phase and three phase circuit?
Yes, there is a difference between single phase and three phase circuits.
Two phase instruments?
There is no such thing as a two phase instrument. There is only single phase and three phase. You can only have: single phase/ one pole single phase/ two pole three phase/ three pole
What are the three types of phase on its final phase?
single phase, double phase & three phase
Can you use this switch for three phase incoming and single phase outgoing?
No A intermediate switch can not be used to change three phase to single phase.
Is the type of wiring in most homes single-phase or three-phase?
Single phase.
What is the advantages and disadvantages of single phase and three phase?
Single phase inherently requires less equipment (it's cheaper). Three phase motors are more efficient than single phase.

What is the need of single phase to three phase conversion?
There is no need of single phase to three phase conversions. Both service types are available from the local utility company.
