Question Paper
1. Explain different types of rectifier circuits for producing high DC voltage. Also draw the waveforms of output voltage.
Define the front and tail times of an impulse wave.
How are the front time and tail time of a wave controlled in impulse generator circuits?
3. Explain how a sphere gap can be used to measure the peak value of voltages. What are the factors that influence such voltage measurements?
4. A resistance divider of 1400 kV (impulse) has a high voltage arm of 16 kohm and a low voltage arm consisting 16 members of 250 ohm, 2 watt resistors in parallel. The divider is connected to a CRO through a cable of surge impedance 75 ohm and is terminated at the other end through a 75 ohm resistor. Calculate the exact divider ratio.
5. Describe the different tests performed on surge diverters before using on high voltage applications.
6. Explain the inductively coupled ratio arm bridge for audio frequency range measurements. Also discuss its merits and demerits.
7. What are electronegative gases Derive the criterion for the breakdown in electronegative gases.
8. Explain the suspended particle mechanism for the breakdown in liquid dielectrics. Also discuss the pure liquid dielectrics.
9. Write short notes on any two of the following:
Hall effect generators for high voltage measurement
Corona Discharge
High voltage testing of circuit breaker
