Benefits

Here are the benefits of Testing The Transformer Oil

Power transformers are essential components of power systems and the most valuable asset in a substation especially for industrial companies. Transformer failure can have a significant economic impact due to long lead times in procurement, manufacturing, and installation in addition to high equipment cost. Unexpected failure is always a major disturbance resulting in unscheduled outages with power delivery problems. Extending the useful life of power transformers is the most important strategy. The most common, essential and important tool used for this purpose is to carry out continuous transformer health condition assessment through monitoring oil parameters which can be done via manual oil testing and/or oil line monitoring sensors. In addition, by regular oil testing and monitoring internal incipient faults can be detected and corrective action taken to prevent sudden failures.
