What do you mean by an exact average temperature of the spark plasma? To my knowledge, the laser sensor tests have measured temperatures that are far too high and then with an accuracy of + - 2000 K. The spectroscopic investigations of single discharges are even more accurate. The problems with the measurement are that the plasma is very small, that the dielectrics interfere with the measurement, that you have to find the place of the discharge, and much more. Just take something, what others have already done is difficult.

Good

Hi. One way is to use Laser optical sensors (high sensitivity) to measure the temperature of the tool/workpiece at the arc root. To predict the temperature, you can use commercially available softwares such as ANSYS FLUENT + ANSYS Electromagnetics to simulate the arcing phenomenon. This would require a good understanding of arc physics.

Hope this helps.

Thank you sir... I will try using Software tools..

Professor, I mean the Exact average temperature is the average temperature.

The temperature induced in the sparking zone is in order of thousand which may be beyond the range of optical pyrometer. So optical pyrometer may not be helpful.

Thank you Uttam ji, Deepti ji for your valuable suggestions..
