It is more economical especially for running motors. Most motors start much better with 3 phase service. It also takes less current than single phase for a motor to run, therefore the power meter spins less for electrical cost.

How are single phase and 3 phase voltages generated?
One hamster vs. three hamsters.
In uk electricity is generated as?
in the uk electricity is generated at ?
What would be the 3 phase voltage on a frequency of 50 Hz?
Single phase and three phase voltages are not related to the frequency at which the voltage is generated. The frequency at which voltages are generated is governed by the speed of rotation of the generating device.
What is the definition of converting electricity?
Electricity is converted from High voltage, 3 phase on the grid to low voltage single phase for domestic use.
What happens to steam after it has generated electricity?
steam is used to generate electricity. what happens to the steam after it has generated electricity?
What is the voltage of 3 phase electricity in UK?
220 volts.
How many coils is required in an alternator to generate 3 phase electricity?
3
Explain how three phases are generated in the UK?
Three phases generated in the United Kingdom should be no different than they are generated anywhere in the industrialized world. Either phase A is followed by phase B followed by phase C, or phase A is followed by phase C followed by phase B
How is static electricity generated?
Static electricity is generated by rubbing two nonmagnetic objects together.
Why is power generated only on 1 or 3-phase not any other?
Most electricity for the power grid is generated as 3-phase because this can be most economically sent long distances on high voltage power transmission lines. While the additional wire and equipment is more expensive than 1-phase, resistive losses are minimized by using high voltage and radiative losses are minimized because the different phases partially cancel each other. Most power transmission lines use 3-phase-delta as it requires no separate return/neutral line (as required by 3-phase-wye, 2-phase, and 1-phase) thus saving some money on these very long lines. Using more than 3 phases would be uneconomical as the costs for additional wire, insulators, poles in switches, transformers, and other equipment would increase without any additional savings beyond the use of 3-phase. By use of transformers the electricity generated, transmitted, and distributed as 3-phase can be converted to whatever must be delivered to the customer according to their needs: 3-phase-delta, 3-phase-wye, 2-phase, or 1-phase. Most industries have 3-phase delivered as either delta or wye because large motors start and run easier and more efficiently on 3-phase than on 2-phase or 1-phase. Also if the industry needs DC, 3-phase is easier to rectify (using a 3-phase bridge rectifier) and filter to get DC with less ripple than using 2-phase or 1-phase. Most homes have 2-phase delivered and use both phases for appliances, and one or the other phase for devices needing only 1-phase power. Most small generators/alternators generate only 1-phase to keep them simpler and less expensive.
What is the Asia's largest producer of nuclear generated electricity?
the asia's largest producer of nuclear generated electricity is Japan.
For a 3 phase alternator why there is an AC voltage generated in the absence DC excitation?
due to residual magnetism
