Hello, friends, I hope you all are doing great. In today’s tutorial, we will discuss the Difference Between Single Phase & Three Phase. There are 2 classifications power systems first one is a single phase and second one 3 phase. The phase is used to drive such loads that needed less power and three-phase is used in industries where high rating load is used.
The basic difference between single-phase and 3 phase system is that in single-phase one conductor and one neutral wire is used while in 3 phase supply 3 conductors and one neutral wire are used to make the circuitry. In today’s post we will have a detailed look at both single-phase and three-phase with the detailed compare them to find their differences. So let’s get started with Difference Between Single Phase & Three Phase.
Difference Between Single Phase & Three Phase
Single Phase
- In single-phase, system power is delivered through a single conductor.
- In this system 2 wires are used for completion of circuitry.
- 230 volts are transferred in this system.
- It also called the Split phase.
- The transfer of power through the system is less than the 3 phase system.
- The system is less complicated than the 3 phase system.
- In single-phase system failure of power exits.
- Power loss is larger in this system.
- Its efficiency is less than the 3 phases.
- It is less expensive than the 3 phase system.
- It used to run home appliances.
Three-phase
- In this system power is delivered through 3 conductors.
- It used 4 wire for completion of the circuit.
- In this system 415 volts can be transferred.
- It has no other name as a single phase.
- The system used in three-phase is complicated than the single phase.
- There is no failure of power that occurs in this system.
- Power losses are less than the single phase.
- Its efficiency is larger than the single phase.
- It used in larger industries where the high load is operated.
What is Single Phase
- In single phase 2 wire are used for the transfer of power and circuit completion first is live conductor and second one neutral.
- In conductor current passes and neutral used to provide a return path.
- Through a single phase two hundred thirty volts can be transferred.
- Single-phase used to run load like fan, heater, etc
What is Three Phase
- There are 4 wires are used in 3 phase system 3 are the conductor and one is neutral.
- The conductive wire is located at one twenty-degree to each other. 3 phase systems can also be used as a single-phase system.
- To provide power to less rating loads one phase and neutral wire can be taken out from the 3 phase supply.
- The power transfer through the 3 phases is continuous and not becomes 0. There are 3 connections in 3 phase power system first is a star and the second is delta. Both are shown in the below figure.
- For transmission of power to longer distance star connection is used since it has a neutral wire through which fault current is flows.
- In delta three conductive wires are taken out and no neutral is exits.
Comparison between Single Phase and Three Phase
- In single-phase one conductor is used for the transfer of power and 3 conductors are used in three-phase.
- In circuit of single phase two wires one is neutral and one is phase used for completion of circuitry. In 3 phase 2 phases wires used.
- Through single-phase two-thirty volts are transmitted and in 3 phase four fifty are transmitted.
- The power transfer though the single phase is less than the 3 phase.
- Due 2 wires use single-phase circuit is less complex than the three-phase sine it used 4 wires.
- The single-phase system uses one phase conductor if there is fault exits in the system the power will totally cut off. While in three-phase 3 phases are used so if one phase is damaged power supply can be get from the other 2.
- The efficiency of 3 phase is larger than the single phase.
- The maintenance of a single phase is costly than the 3 phase system.
So friends that is a detailed post about the difference between single-phase and three-phase if you have any query ask in the comments. Thanks for reading. have a good day.
