How do i measure the dielectric breakdown of air? - equipment breakdown
Hello,
I want to know whether a particular device for measuring the dielectric breakdown of the air? Or is there a way to build something that can?
Besides, if I wanted an experiment to carry out the distribution of air dielectirc measure, what are the independent and dependent variables and factors are held constant?
Any help would be very grateful!
Thanks

Equipment Breakdown How Do I Measure The Dielectric Breakdown Of Air?

You do not know why, because he has done and can not read books.
However, if you want, should have a pair of parallel plates obtained with rounded edges. The reason is that the side effects discard (concentration of the electric field due to the curvature of the edges of the plate) to their results. These plates are in place, but I do not know where. I'll start with buildings such as Sargent-Welch Lab Products (if you're in the U.S.).
You need to prevent a high-voltage training, like you, that shocked her.
The shear strength of air is nominally 30 kV / cm to 3 MV / m under normal conditions. Factors, which is the tensile strength of the actual air pressure, gas composition and humidity.
If you can field the potential distribution between two plates with very large rooms to increase (the distance known) arc decomposition want to know is experiencing (or). The generally accepted that about 10,000 V / m. The parameters that are different from the accepted value, are things like the composition of air, humidity, atmospheric pressure, temperature ... etc.
It is unlikely that the team the platform to measure the dielectric gas, but probably expensive. All it takes is a simple series circuit with a variable high voltage transformer in the area of what is known that a number of electrodes to decompose, a container received in the pure sample, and to know some devices output as an LED to When the break, if you interested, some are constructed to occur. As for variables to consider, what are the properties of air are the variables. For example, the share of gas, humidity, dust, motion, temperature, etc. See www.wikipedia.org for more ideas.
