How much oil is in a substation transformer?

Power transformers, reactors, and regulators may contain anywhere from a few hundred to 100,000 l or more of oil (500 to approximately 30,000 gal), with 7500–38,000 l (approximately 2000–10,000 gal) being typical.

What is the formula of transformer oil?

The transformer oil used in India is paraffin based having long chains of hydrocarbon, with general chemical formula, C nH2n+2.

Which oil is best for transformer?

Naphthenic mineral oil
Naphthenic mineral oil has long been the most preferred insulating liquid for power transformer insulation because it has a good pouring point at low temperatures, good thermal cooling capacity, low cost, high efficiency and availability on the transformers market [1, 2, 3, 7].

What is the weight of 100 kVA transformer?

Are pole mounted transformers oil filled?

The most common type of distribution transformer used in North America is the single-phase oil-filled, pole-mounted transformer, normally referred to as a “pole-top” or “overhead” transformer.

What is PCB transformer oil?

Polychlorinated biphenyls (PCBs) are synthetic chemicals which are no longer produced in the United States, but are still found in the environment. PCBs have been used as coolants and lubricants in transformers, capacitors, and other electrical equipment because they don’t burn easily and are good insulators.

Which oils are used in transformer?

Mineral oil and Synthetic oil are the majorly used transformer oil. These are the petroleum products, like Naphthenic based transformer oil and Paraffinic based transformer oil.

What is the name of oil used in transformer?

Three basic types of transformer oil used are mineral oil (mostly naphthenic), silicone, and bio-based. Mineral oil based transformer oils dominate the consumption as it has good electrical and cooling properties, and provides cost-effective solution.

What is the viscosity of transformer oil?

High quality transformer oils are normally in the range of 7- 8 mm2/sec at 40°C and even with such low viscosity, they still meet the requirement for flash point (<135°C) from the same standard.
