PARAMETRIC ANALYSIS OF IMPULSE VOLTAGE GENERATOR
SIMULATOR
EQUIVALENT CIRCUIT DIAGRAM
INSTRUCTIONS
- The objective of this experiment is to observe the variation in output
waveform by varying one parameter and keeping all the others constant.
- When the page loads the user is presented with three input parameter
buttons namely Tail Capacitance(Cl),Front Resistance(Rf),Tail Resistance(Rt)
on left frame and a circuit representation of IVG on right frame.
- One of the parameter buttons is clicked to continue the experiment for parametric analysis.
- The user gets a display of non-editable parameters namely Charging voltage(VO),
Ground Capacitance(Cg),Front Inductance(Lf),Load Inductance(Ll),Tail Inductance(Lt)
with default values and two editable parameters namely parameter button choosen(Cl,Rf,Rt)
with default values.
- The editable parameters are changed by adjusting slider position.
- Then click on open ground switch to give supply to IVG and you can see it in simulator
- The Charge Capacitor button is to be clicked to charge generator capacitors.Charging time of capacitor is displayed by bar on left corner of simulator
- The Trigger generator button is to be clicked to display the mechanism of IVG and the fact that Breakdown has occurred or not is displayed.
- After complete the process the respective graph will be shown. Different alert statements are included to direct the user whether there are withstand or flashover occurs between sphere gaps.
View the waveform carefully how waveform is changing with variation in parameters. And also different wave forms are generated for withstand and flashover.
- Mouse-hover on wave to see the variation of generated voltage with time. You can drag it or Zoom In/Zoom Out the wave form for detail study.
- Find out Front time and tail time from the wave from for each waveform and compare them (Front time = 1.25 times of time time taken by waveform to reach 10% to 90% of peak value, Tail time = Time taken by waveform to reach 10% to 50% of peak value while decaying).
- after finding front time and tail time you can compare the generated Impulse wave with standard switching impulse wave.
