Power Grid

Power Plant Generates electricity to be distributed to our homes and businesses. Non-renewable: Fossil fuels Nuclear energy Renewable: Solar Hydroelectricity Wind Tidal Geothermal

Step-Up Transformer Increases voltage in the electrical grid because of loss due to electrical resistance

Power/Transmission Lines High power lines that carry electricity from power plants to our homes and business.

Substation Decreases electrical energy 155,00V7,200V Examples: Bull Frog corner 51/Starlanding HLHS/Latimer Park

Step-Down Transformer Decreases electrical energy 7,200V240V Found on telephone poles by homes and business Looks like trash cans

Homes/Businesses Electricity is transmitted on two lines with 120V each. Some electrical energy is lost due to electrical resistance 110V (single line) TVs, computer, fans, cell phone charges, toaster 220V (double line) Washer, dryers, ovens, hot water heater
