Answer 1

Here's your answer to the question asked by you

Answer 2

Advantages;

Safe Operation :

If we acknowledge the benefits of Underground Powerhouse for power distribution and broadcast than covered power cables are reliable than the hanging power line. So the possibility of the hazard incident is very limited.

The main problem of the overhead power line is it is further prostrate to environmental possibilities. When thunderbolt and winds happen in the above lines it is more tend to get vitiated. But for the underground power line, the inclination for getting casualties due to the environmental hazards are considerably limited.

Disadvantages;

High Capital Cost:

One of the major limitations of the Underground Power systems is its original cost. In association to overhead transmission or frequency, the cost for construction of the underground system is exceptionally high.

2. Can’t Use for High Voltage Levels :

Another limitation is due to the season when the insulation can get exhausted so an air space can develop inside the insulation. Since the power surrenders on huge energy level the air inside becoming ionized and the advance the collapse of the insulation.
