Question Paper

1. Draw a typical impulse current generator and explain its operation and application.

2. A 12-stage impulse generator has 0·126 MF capacitor. The wave front and the wave tail resistance connected are 800 ohms and 5000 ohms respectively. If the load capacitor is 1000 MF, find the front and tail time of the impulse wave produced.

With the help of a suitable diagram, explain the working of a Van de Graaff generator used for generation of impulse voltage.

What are the advantages and disadvantages of Van de Graaff generator?

4. Explain the construction and working principle of an electrostatic voltmeter with the help of a suitable diagram.

5. Explain in detail the various factors influencing the spark voltage of sphere gap used in high voltage measurements.

6. Draw a high voltage Schering bridge for measurement of dielectric loss of a specimen, which is not grounded and derive an expression for loss angle.

7. What do you understand by intrinsic strength of a solid dielectric? Explain the electric breakdown of a solid dielectric.

8. Explain Streamer's theory (mechanism) of breakdown in detail, with the help of suitable diagrams.

What is "treeing" in case of breakdown of solid dielectric Draw a neat sketch of "treeing".

Define Townsend's first and second ionization content.

10. Write short notes on any two of the following:

Paschen's Law

Hall Effect Generator

Voltage Doubler

Rogowski Coil
