What oil is used in transformers?
Transformer oil, also known as insulating oil, is commonly used in transformers. The most common type is mineral oil, derived from the refining of crude oil. It has excellent insulating properties and helps dissipate heat generated by the transformer.
In some cases, biodegradable oils or synthetic oils are used, particularly where environmental considerations are important.
Oil is present inside the transformer mainly for two reasons: insulation and cooling.
The oil acts as an electrical insulator, preventing short circuits and electrical breakdowns inside the transformer. Additionally, it helps dissipate heat generated during transformer operation, thereby maintaining optimal performance and preventing overheating.
What is transformer oil called?
The transformer oil level should be monitored regularly to ensure it is within the recommended range. Generally, the oil level should be between the minimum and maximum marks on the transformer oil gauge.
It is important to maintain a proper oil level to ensure adequate insulation and cooling, and to prevent air from entering the transformer, which could cause insulation failure.
What oil do transformers use?
The cost of transformer oil can vary depending on factors such as the type of oil, quantity purchased, and market conditions.
Mineral oil is generally less expensive than specialty biodegradable or synthetic oils. Cost is usually measured per liter or per gallon, and prices can fluctuate based on supply and demand, as well as the quality of the oil.
The breakdown voltage of transformer oil is an indicator of its insulating resistance. It measures the voltage at which oil begins to conduct electricity and break down. A typical breakdown voltage for transformer oil should be at least 30 kV for a 2.5 mm gap.
Higher breakdown voltages indicate better insulating properties and oil quality, which is essential for the safe and reliable operation of transformers.
