FAQs
What is the main purpose of an oil-immersed test transformer?
A: The primary purpose is to test the insulation strength of electrical equipment by applying high-voltage. This helps identify any weaknesses in insulation materials. It’s commonly used in power stations, distribution networks, and research labs.
Why is oil used instead of air in these transformers?
A: Oil is used because it offers better cooling and insulation than air, allowing the transformer to handle higher voltages in a more compact size. It also helps prevent arcing and dissipates heat more effectively.
How do oil-immersed and dry-type test transformers compare?
A: Oil-immersed transformers are ideal for high-voltage, outdoor use as they handle more power and have better thermal efficiency. Dry-type transformers, however, are safer for indoor use because they don’t contain flammable oil.
What maintenance is required for these transformers?
A: Regular maintenance includes checking oil levels, monitoring temperatures, and inspecting for leaks. You should also test the dielectric strength of the oil and inspect the bushings for cracks every few months. Annual checks should include electrical tests and oil filtration if needed.
What are the disadvantages of using oil?
A: The main drawbacks of oil are its fire risk and environmental impact. If the transformer leaks, the oil can contaminate the ground and water, and the oil itself is flammable, which could lead to explosions under extreme conditions.
