What are the Different Methods of Different Power Transmission? (What are the different methods of different power transmission)

Hello friends in this article we will know that different power Transmission different methods of different power transmissionWhat are and we will also learn that in different transmission systems caper How does the volume of . And learn about many facts related to it.

Different methods of different power transmission

Although 3-phase, 3-wire AC is used for power transmission. The system is widely used and provides 3-phase, 4-shire AC. The system is used for distribution, but other systems are also used for power transmission for other applications. These are the following –

DC. Systems (DC Systems) –


  1. DC 2- Shayar System
  2. DC 2-Wire, mid point ground
  3. DC 3- Poetry System

Single Phase AC Systems –

  1. Single Phase 2- Wire
  2. Single phase 2- wire mid point ground
  3. Single Phase 3- Wire

2- Phase AC Systems –

  1. 2- Phase, 3- Wire
  2. 2- Phase, 4- Wire

3- Phase AC Systems –


  1. 3- Phase, 3- Wire
  2. 3- Phase, 4- Wire

The basis for comparison of different systems of power transmission is generally ‘Volume of copper required’.


Comparison of volume of copper for Different Transmission System –

The following assumptions are made while comparing the volume of copper for different systems-



  1. The power transmitted is the same on all systems.
  2. The transmission lengths are the same in each system.
  3. Line loss is the same in all systems.
