Transformer State Monitoring Devices
Temperature
Overheating will accelerate the aging process of cellulose paper and other insulating materials in a transformer, shortening its lifespan over time.
Pressure
Pressure builds up in the transformer due to the temperature increase sustained by A14:E17, in the event of an internal fault or under excessive load, negatively impacting the tank walls and other internal components.
Humidity
With the passage of time, excessive moisture can cause the deterioration of a transformer`s insulation properties. This negatively affects both the solid (paper) and liquid (oil) insulation, ultimately shortening the transformer`s lifespan.
Liquid Level
Monitoring the level of insulating fluid inside a transformer is crucial for its condition. A high level may indicate overfilling or overheating, while a low level may indicate a catastrophic leak in the system.
DGA
Overheating and arcing within a transformer can release various gases that can be used to identify potentially problematic areas and help avoid catastrophic failures.
Incomplete discharge
Partial discharge monitoring provides information, such as the location of small sparks that occur inside insulation as a result of aging or deterioration.
