Function of the explosion vent in the distribution transformer:
- When an internal fault occurs within the transformer, such as a short circuit or insulation breakdown, it can generate high-pressure gases.
- These gases can rapidly increase the pressure inside the transformer tank.
- The explosion vent is designed to release this excess pressure when it reaches a predetermined level, typically around 5 psi.
- By releasing the pressure, the explosion vent prevents the transformer tank from bursting or being severely damaged.
- It also helps to prevent potential hazards, such as fire or injury, associated with a transformer explosion.
