Copper and aluminum are commonly used conductors in transmission.

• Copper is an excellent conductor due to its high electrical conductivity.

• Aluminum is also widely used as it is lightweight and cost-effective.

• Other conductors like silver and gold are rarely used due to their high cost.

• Copper-clad steel conductors are used in specific applications where strength is required.

Different types of tests related to transformers include routine tests, type tests, and special tests.

• Routine tests are performed on every transformer and include measurement of winding resistance, insulation resistance, and voltage ratio.

• Type tests are performed on a sample transformer to verify its design and include temperature rise test, impulse test, and short-circuit test.

• Special tests are performed on transforme...read more
