Monitoring the level of insulating fluid within a transformer is vital to its health. A high level may indicate overfilling or overheating whereas a low level may indicate a catastrophic leak in the system.
Dissolved Gas
Overheating and arching in a transformer can liberate a variety of gases that can be used to pinpoint potential problem areas and help avoid catastrophic failures.
Partial Discharge
Partial discharge monitoring provides information such as location on the small electrical sparks that occur within the insulation as a result of aging or deterioration.
Overheating in a transformer can signal a potential issue and cut the useful life of the asset. As the temperature rises the cellulose paper and other insulating materials inside will start to breakdown. Understand the temperature profile within the transformer and provide a window into the asset to mitigate the risks and plan preventative actions before its too late.
Basic thermometers provide insight into oil or simulated winding temperatures
Fiber Optic Sensors provides the most accurate hot spot temperatures within a winding
Variety of transformer monitors to trend temperatures and have smart algorithms to assess the remaining life within an asset
Moisture intrusion into a transformer can signal a major issue within the asset. Over time, water can break down the insulating properties of the oil and cellulose paper, causing irreversible damage. Qualitrol’s family of TM Series DGA sensors have an optional moisture probe to measure water within the insulating fluid.
