Electric-POWER transmission system is the system used for bulk transfer ofelectrical energy, from generating power plants to ELECTRICAL substations located NEAR demand centers. The different systems of transmission are:

• DC system
• Single phase AC system
• Two phase AC system
• Three phase AC system

The part of power system which distributes electric power for LOCAL use is known as Distribution System. The different distribution systems are:

• AC Distribution system

1. Primary distribution system
2. SECONDARY distribution system

• DC Distribution system

1. 2 wire DC system
2. 3 wire DC system
