Study Notes
Electrical Supply System Layout
- Power generation occurs at power plants using fossil fuels, nuclear, or renewable resources.
- Electricity is transmitted via high-voltage transmission lines to minimize energy loss over long distances.
- Distribution networks deliver electricity to residential, commercial, and industrial consumers using lower voltage lines.
- Substations reduce voltage levels for safe usage and manage electricity supply during peak demands.
Safety Measures in Electrical Systems
- Circuit breakers protect against overloads by interrupting current flow during faults.
- Grounding systems provide a path for stray currents, reducing the risk of shocks.
- Residual current devices (RCDs) prevent electric shocks by disconnecting power when leakage is detected.
- Regular maintenance and inspections ensure equipment safety and compliance with standards.
Introduction to Renewable Energy Resources
- Renewable energy resources include solar, wind, hydroelectric, geothermal, and biomass.
- These resources are sustainable and contribute to reducing greenhouse gas emissions.
- Integration of renewables into the power grid supports energy independence and security.
Overview of Energy Storage Systems
- Energy storage systems, such as batteries and pumped hydro storage, balance supply and demand.
- They enable the use of excess electricity generated during low demand and store energy for peak usage.
- Essential for enhancing grid stability and integrating more renewable energy sources.
Purpose of Practice Session
- The practice session enhances understanding of theoretical concepts through hands-on experience.
- It provides practical skills in electrical system design, safety protocols, and problem-solving.
- Encourages collaboration among participants, fostering teamwork and communication in technical settings.
