stator on the oven... trend

stator on the oven... trend

stator on the oven... trend

(OP)
hi, i had read in a manual (Marelli generators, Italy) that they talk about generators heating to take out humidity on the oven, and you´ll see a trend... and recomendations, in example, measurements of isolation each hour... and you´ll see, the trend of insulation rise and after some time decrease... and then rise again to the final and stable point.... why this trend? and why to cheek insulation each hour?

and why to check insulation each hour?
Well if you want to see a trend  you are going to have to check at some regular period.


As for that particular trend?  Someone else will have to say.

but why that particular trend? why up, then down and up again??
 

RE: stator on the oven... trend

I think (stress on the think) that I read somewhere it is because as the moisture "bakes" out of the insulation (Sort of like steam) the IR values will drop from the humidity, than as the insulation moisture contect decreases, the IR values go back up and exceed the pre bake values.
