Re: [PSES] Interesting material

Thanks, Aldo.

Separately, effects on inanimate objects like ESD materials and transmission 
lines seem generally sensitive to relative humidity whereas humans, and likely 
other mammals, are sensitive to absolute humidity measured as dew point 
temperature. As temperature is not important up to 120?F, or more, if the dew 
point temperature is below freezing.

Once I realized this some time ago and applied it to myself, I have no problem 
running for an hour or two at 115?F in the Nevada desert passing signs that say 
"Danger! Do not enter here in the summer!" Most young athletes are not able to 
do this, yet I will be 76 in a few weeks.

Here is a better video where I limit the applied voltage to a reasonable 
operating voltage to just see the humidity effect.

Re: [PSES] Interesting material

Dear Doug,

 

Very interesting!  I am aware of humidity level that affects the insulation.  
Thanks for your experiments that show the spark as well.  If the humidity would 
affect the leakage current, I do not notice the standard gives the humidity 
condition for the current measurement.  Is there any default condition applied?

 

Regards,

 

Scott

Hi All,

 

I was testing a new material for a different purpose and accidentally found 
that it was very sensitive to humidity/moisture. Might make a good humidity 
alarm for an industrial process or other application. What do you think? Here 
is a short video:
