Option 1 : Dead
The dead short circuit is the most dangerous of all short circuits.
This is because:
- A dead short is an electrical circuit that results in current flowing along an unintended path with no resistance or impedance.
- This results in an excessive current flowing through the circuit, which can damage equipment or cause electrical shocks to those nearby.
- A dead short is difficult to track and diagnose as the current builds rapidly and trips the breaker immediately.
- It is mainly caused due to direct connection between positive and negative power wires or a direct connection between the positive wire and the ground.
Ground fault:
- The ground fault occurs in the power system when the hot wire (live wire) is accidentally connected with the earth wire or grounded equipment frame.
- In this condition, the frame of equipment energies with dangerous voltage.
