Procedure to do the Experiment

1. When the page gets loaded the value of Diameter of the sphere should be choosen from the displayed dropdown box.

2. The sphere gap distance values gets populated in response to the selected sphere diameter in another drop down and one of the value should be selected.
   

3. The type of polarity should be choosen.
   
   
4. The Temperature and pressure values should be mentioned in the corresponding text boxes.
   
   
5. The Setup_IVG button is clicked to display the Applied Voltage values drop-down box and the no.of pulses to be applied on the voltage in the form of radio buttons.
   
   
6. The enabled Applied Voltage value(kV) is selected from the displayed drop down box.
   
   
7. The pulses are applied on the selected voltage value by selecting the enabled radio button one at a time.
   
   
8. The fact that Breakdown has occured or not is displayed by the flash object.


9. The Break-down probability for each voltage level is calculated as Number of pulses break-down divided by Total Number of pulses.


10. Steps 7 & 8 are repeated for next enabled pulse.


11. Steps 6,7 & 8 are repeated for all applied voltage values to complete the Experiment.


12. The show Graph button will be displayed at the end of the experiment.


13. The button is clicked to display the variation of the Applied Voltage versus the Breakdown probability.


14. The critical flash over voltage value (for given sphere diameter and gap spacing) namely the voltage value for 50% probability of breakdown is displayed prominently on the graph.
