Understanding Electrical TransmissionDemonstration C2 A Guide to the National Grid Transmission Model Demonstration C2 Why are high voltages used for transmission?

Understanding Electrical TransmissionDemonstration C2 A Guide to the National Grid Transmission Model Task 1 Low-voltage transmission

Understanding Electrical TransmissionDemonstration C2 A Guide to the National Grid Transmission Model 1. Can the generator provide enough power for the maximum load on the load unit? The voltage across the transmission leads is now measured at the start and at the end. 2. What is the voltage across the transmission leads at the start? What is the voltage across the transmission leads at the end? 3. What causes this difference?

Understanding Electrical TransmissionDemonstration C2 A Guide to the National Grid Transmission Model Task 2 High-voltage transmission Make sure the generator is switched off each time you connect or disconnect components.

Understanding Electrical TransmissionDemonstration C2 A Guide to the National Grid Transmission Model 4. Can the generator provide enough power for the maximum load on the load unit? 5. What effect does using a higher voltage for the transmission leads have? Why is this? The voltage across the transmission leads is now measured at the start and at the end. 6. What is the voltage across the transmission leads at the start? What is the voltage across the transmission leads at the end? 7. How does the voltage drop for high-voltage transmission compared to that for low-voltage transmission? Why is this?

Understanding Electrical TransmissionDemonstration C2 A Guide to the National Grid Transmission Model Task 3 Measuring frequency 8. How does the frequency at the generator compare to the frequency at the load? 9. What effect does increasing the load have on the frequency? 10. How can a constant frequency be maintained even if the size of the load varies?
