Question 1: When designing an underground electrical distribution system, how do you address issues related to thermal dissipation in the cables?

Which action should you take?

Choose only one option

By increasing the overall system voltage to prevent overheating

By selecting appropriate cable insulation and considering depth of burial

By using air cooling systems for cables buried underground

By reducing the cable size to lower the thermal resistance

Question 2: What is the impact of high R/X ratio on load flow solution?

Which action should you take?

Choose only one option

No impact

Slows convergence

Improves convergence

Causes divergence

Question 3: In electrical panel design, why is segregation between compartments important?

Which action should you take?

Choose only one option

Allows ease of maintenance

All of the above

Reduces arc flash risk

Prevents short circuits

Question 4: What is the significance of the power factor in electrical system design, especially in large industrial facilities?

Which action should you take?

Choose only one option

It only influences the cost of electricity bills for consumers

It has minimal impact on system design as long as voltage levels are stable

It affects the size and efficiency of transformers and generators

It determines the type of protective relays needed

Question 5: Which type of protective relay is most effective in the detection of earth faults?

Which action should you take?

Choose only one option

Distance relay

Overcurrent relay

Differential relay

Earth fault relay

Question 6: When performing load flow analysis, what happens if the load demand exceeds generation capacity?

Which action should you take?

Choose only one option

There will be a temporary increase in voltage at the slack bus

It results in an under-voltage condition at load buses

The system will go into a voltage collapse

The system will operate in a stable condition
