Do you know what isPartial Discharge?
Self accelerating process (it just goes worse).
Discharge ⇒ material deterioration ⇒ more intense discharge... :-(
It's within solid insulation system and therefore not visible!
Time-difference look-uptable method FTW*!
#1 #3
#2
* For The Win
FDTD s imulat ionPD posit ion
UHF s ignals
Ok, let's RECAP
We already have look-up table
We already have measurement data
Final step? Compare all the things!
Step #1
Step #2
CONCLUSION
But, it's fast
And relatively accurate
Sensors location may be crucial
You need simulation and measurement
(just comparison)
(371 mm vs. 617 mm - 40 %)
