1.3.5. Safety

Try these first

1. 1.

   What does overcurrent protection do?

   Hint

   Think about how fuses work.

2. 2.

   What is the purpose of insulation in electrical systems?

   Hint

   Consider how we keep high-voltage wires safe from human touch.

3. 3.

   What is the primary purpose of overcurrent protection?

   • To enhance efficiency
   • To prevent circuit damage
   • To increase power output

   Hint

   Think about what happens when too much current flows.

4. 4.

   True or False: Thermal shutdown devices disconnect power when temperatures are too low.

   • True
   • False

   Hint

   Think about why we want to keep components cool.

5. 5.

   Design a comprehensive safety plan for a high-power circuit used in an electric vehicle. Include at least three safety mechanisms and justify your choices.

   Hint

   What risks do you want to mitigate in an electric vehicle?

6. 6.

   Evaluate the failures in a case where inadequate overvoltage protection resulted in equipment damage during a lightning storm. What could have been done to prevent this?

   Hint

   Think about the conditions during a storm and how electricity behaves.
