Principle of Power Transformer Pressure Mutation Protection

Principle of Power Transformer Pressure Mutation Protection

Principle of Power Transformer Pressure Mutation Protection
Sensing a transient increase in pressure inside the tank at a particular fault and acting in response to a dynamic increase in pressure inside the tank due to an accident.
When the transformer internal fault occurs, the pressure in the oil chamber rises suddenly, when the rising speed exceeds a certain value, the pressure reaches the action value, the pressure switch will act, send a signal to alarm or cut off the power supply to make the transformer out of operation.
The guard operates faster than the pressure relief valve, but does not release internal pressure.
