Understanding the Benefits of 3-Phase Power Distribution

A system containing more than one phase is usually known as a 3-Phase System. It uses 3 wires to supply the power to the equipment and machinery. In 3-Phase power distribution, all phases have a consistent frequency as they have a stationary angle of 120 degrees between the resource voltage and the alternator. 3phase system is an alternative way to drive more power to the system using less infrastructure.

3-Phase Power Distribution is commonly used by industries and businesses which have heavy power requirements. The reason for this is 3 phase range Genset distribution helps them deliver more power efficiently. Besides these systems ensure a very smooth and consistent flow of power. Now let us look at some of the key benefits of 3-Phase power distribution has:

Output
A 3-Phase power distribution system gives more output compared to a single-phase system. The values ​​of output are almost 1.5 times greater than single-phase systems. In addition to this, a 3-phase system also requires considerably less space to install.

Reliability
In a 3-phase power distribution system, the network consists of three phases. So, when any type of fault happens in one of the phases, the other two phases continue to distribute the power or serve the load. This feature of a 3-Phase system increases its reliability in case of any failure.

Uniform Torque
One of the key advantages of using a 3-phase system is that it gives uniform torque as compared to single-phase systems which provide pulsating torque. Thus, the power obtained by using 3-phase systems is cumulative and balanced.

Cost-Effectiveness
3-phase power distribution systems prove to be more economical as they have the ability to supply more power. 3-phase distribution systems have conductors with a very small cross-sectional area which makes it cheaper to transmit power. These systems have a very high ratio of power to weight when compared to single-phase systems due to which the overall cost of the systems gets reduced and as the weight gets reduced the cost involved in logistics and installation of the system also gets reduced.

Maintenance
Due to the high reliability of 3-phase power distribution systems, they require minimal maintenance compared to single-phase distribution systems. Also since there are fewer systems to deal with in total this means that the downtime gets minimum and thus reduces the overall maintenance economically.

Rectifier System
The 3-phase power distribution system has a smoother rectifier system which makes it easy to sort out the ripple elements. A rectifier system used in #-phase systems has the value of a ripple factor of 4 percent while in a single-phase system this goes up to 48 percent. So, there is a minimal requirement of filter in 3-phase power systems which in turn reduces the cost involved in the installation of a converter in the system.

Some of the other advantages of using 3-phase power distribution systems are:

1. 3-phase systems can be operated in parallel very easily due to their almost zero pulsating reaction.
2. The value of the power factor is high in 3-phase systems which aid in the improvement in voltage to the equipment and help reduce overall electricity costs.
3. 3-phase systems are self-starting in nature because they get a magnetic flux due to the 3-phase supply with a uniform magnitude. This actually eliminates the use of any external auxiliary device to start the system.
4. Lesser voltage drops are observed in a 3-phase power distribution system from the source to where the load point is located.
5. In a 3-Phase distribution system, the rating of output can be increased by increasing the number of phases.
6. Less cabling and labor are required in the installation of 3 phase power distribution systems.
7. The overall system voltage is lower which makes 3-phase power systems safe to operate with.
8. 3-Phase power distribution systems are comparatively smaller in size while maintaining the same output rating.
9. There is high efficiency in the devices and appliances which operate on 3-phase power distribution.
10. A 3-phase power distribution system offers us two different types of voltages ie, 230/400 volts while using a single system.
11. A 3-Phase power distribution system can be used to feed a single-phase power distribution system while vice versa cannot be done.
12. Due to the high power to weight ratio of a 3-phase power distribution system for the same amount of power the size of the system gets reduced due to which the overall cost for the distribution also gets reduced and the space requirement reduced.
13. Large Power in Megawatts can be economically moved through High Voltage Transmission Lines in a 3-phase power distribution system.
14. If 3-phase currents are balanced, they cancel out and no return path is required. Likewise, if 3-phase fluxes are balanced in a magnetic core, they cancel out and hence no return limb is required.
15. The voltage of Large AC Power can be economically stepped up or stepped down in a 3-phase power distribution method compared with Mono Phase systems.
16. The immediate power in a 3-Phase system can be continuous (not pulsing). This results in equal power transmission and less trembling of 3-Phase machines.
17. Even when more than 3 phases are needed, they can be provided by manipulating the available three phases in the 3-phase power distribution system.
18. There is less loss of power due to resistance due to less conducting materials. This makes the 3-Phase power distribution more effective and economical.
19. 3-phase power distribution gives us an option for variable voltage through the same circuit which is required by many industries.
20 The output of 3-Phase power distribution will be much higher than the single-phase power distribution system even if the frame size of both the systems is the same.

Conclusion
It is very much clear from the above advantages that 3-phase power distribution is better than the rest power distribution system and this is the reason why it is widely used in transmission line where the power gets transferred from the power plant to further distribution centers . So, now that you know the advantages, it will be easier for you to decide and purchase.
