i need this question to be solved asap...

Hint:we have to apply voltage using the ramp function to steadily increase it and then use damping function to exponentially decrease it and in the start we have to use spark gap to show over voltage for 2-4 seconds.

Experiment No. Objective: "Transient generated due to switching over voltage a) Transient generated after fault clearance. b) Over voltage generated due to disconnection of unloaded transformer. c) Over voltage generated due to capacitance switching, Software Used: MATLAB (R.2009) Theory: The insulation has the lowest strength for switching surges with regard to long air gaps. Further, switching over voltages are of relatively higher magnitudes as compared to the lightning over voltages for UHV systems. Over voltages are generated in EHV systems when there is a sudden release of internal energy stored either in the electrostatic form in the capacitance) or in the electromagnetic form (in the inductance) a) Transient generated after fault clearance Vin out R L 0000 MATLAB Code: MATLAB Results: b) Over voltage disconnection of transformer. generated due to unloaded isolation transformer Circuit breaker MATLAB Code: MATLAB Results: c) Over voltage generated due to capacitance switching.
