Product Q&A
Q:What is the life expectancy of an oil-immersed transformer?
A:
Around 20-30 years
The typical lifespan of an oil-immersed transformer is around 20-30 years, but some high-voltage models that are kept in pristine conditions can last 50 or 60 years! Most of the time, these transformers will outlast the career of the person who ordered or installed them.
Q:What happens if there is moisture in transformer oil?
A:
Moisture in a Transformer
Moisture is a significant concern for power transformers and can lead to unexpected failure of equipment and unplanned outages. Excessive moisture in the oil of a transformer reduces the oil's dielectric strength. This introduces the opportunity for flashover and arcing.
Q:What happens if you underload a transformer?
A:
In reality, transformers running at underload hampers its longevity and efficiency. When a transformer is not correctly sized, the underloaded condition would result in high harmonic currents. This may also cause heating of transformers. All of this sum up to cause poor performance of the transformer.
Q:What is meant by power transformer?
A:
Power transformers are electrical devices designed to transfer electrical power from one circuit to another without altering the frequency. They function on the principle of electromagnetic induction and are essential for transmitting power between generators and primary distribution circuits.
Q:What is considered a power transformer?
A:
Power transformer is known as a kind of static electrical equipment undertaking the responsibility of transforming alternating current/voltage as well as transporting alternating electricity.
