Q2. What is the Vdv test in transformers?
Ans. 
The Vdv test assesses the insulation resistance and dielectric strength of transformers to ensure safe operation.
• Vdv stands for Voltage, Dielectric, and Voltage test.

• It measures the insulation resistance of transformer windings.

• A typical test voltage might be 500V or 1000V, depending on the transformer rating.

• The test helps identify potential insulation failures before they lead to breakdown.

Q3. What is the function of a Buchholz relay in a transformer?
Ans. 
A Buchholz relay detects gas and oil flow changes in transformers, providing protection against faults.
• Monitors gas accumulation due to insulation failure or overheating.

• Detects sudden oil movement caused by internal faults.

• Provides alarm signals for maintenance or immediate action.

• Commonly used in oil-immersed transformers.

• Example: If a transformer overheats, gas is produced, triggering the relay.
