Vault Transformers

Qualitrol combines unique algorithms, sensors and monitors to provide you with unique solutions for retrofits and new build opportunities.

Temperature

Overheating in a transformer will acclerate the aging process of the celulose paper and other insulation materials. According to IEEE Standards C57.91, approximately each 6-8 degree increase in temperature will doubles the rate of decay in the transformer limiting it's useful life.

Pressure

Pressure builds within a transformer due to temperature increases sustained during an internal fault situation. Qualitrol manufactures a variety of pressure devices to mitigate pressure build-up within a transformer.

Liquid Level

Often overlooked as an important indicator, measuring oil level is a necessity as it monitors the insulating fluid in the transformer. A high level may indicate overheating conditions as the oil is expanding or indicate over-filling of the tank. A low level may indicate a leak or a catastrophic issue.

Dissolved Gas

Dissolved gas is a vital indicator of the winding health of the transformer. Overheating and arching liberate a variety of gases that can be measured and used to pinpoint potential problem areas to avoid catastrophic failures.

SYMPTOM CHECKER

Overheating Overpressure

Overheating in a transformer can signal a potential issue and cut the useful life of the asset exponentially as the temperature rises. Excess heat in a transformer causes a breakdown in cellulose paper and other insulating materials inside.

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 temperatures with local indication or remote alarming capabilities depending on the need
Variety of transformer monitors to trend temperatures and have local indication and alarming capabilities.
