Being a foreign stranger or a strange foreigner, I cannot distinguish, nor discriminate, nor differentiate nor even discern or descry which words are of current casual regular use from others.
I took the word keraunic from one of Don White's books: Lightning & Lightning Protection, a mandatory reading for my engineers. Our collection (to speak only of those edited by Don White in the '90s) :
- The Aerospace Engineer's handbook of Lighning Protection
- Shielding design, methodology and procedures
- Grounding for the control of EMI
- Electromagnetic Shielding, Materials and Performances
- EMP environment and System Hardness design
- EMI Control in the Design of Printed Circuits Boards and Backplanes
- EMI control in Aerospace Systems
- Lightning & Lightning Protection
On another topic, I agree on your comments in your post on the same thread about the virtues of fast recovery diodes, and SiC among them. The less energy in the inverse conduction pulse, the less energy will energize the stray resonant tanks around the diodes (wire inductance, interwiring capacitance).
But replacing standard diodes by SiC diodes or other fast recovery techies tries to mitigate the consequences (a dv/dt kick making the whole damned PS to resonate with slowly decaying oscillations) instead of the cause: crappy wiring, bad choice of transformer, and no damping of oscillations (see reference to some ancient article by J Hagerman in the same thread) .
As for trailer parks, we don't have them, but Gypsies. Somehow different, I think. They had the reputation to bring plague and bad luck, but not to attract lightning (to increase the keraunic level, to speak PC)
