What is the overall flow of power from generation to Generation Plant → Step-Up Transformer → High Voltage Transmission Lines
customers? → Transmission Substation → Step-Down Transformer → Distribution
Substation → Distribution Feeders → Homes / Businesses / Industry
What is the primary purpose of the transmission To move large amounts of power long distances efficiently.
system?
What are typical voltages used in transmission 69 kV, 138 kV, 230 kV, 345 kV, 500+ kV
systems?
What are the characteristics of a transmission system? Tall steel towers, long-distance lines, bulk power transfer, connects
generating stations and substations.
What is the key idea regarding voltage and current in Higher voltage = lower current for the same power, leading to less heating
transmission? losses and more efficient transport.
What is the formula for power loss in transmission? P_loss = I^2R
What is the purpose of the distribution system? To deliver usable power to customers.
What are typical voltages used in distribution systems? 34.5 kV, 13.8 kV, 12.47 kV, 4.16 kV, 240/120 V residential.
