I wonder what the below properties mean
+ Sparkover
+ Impulse Sparkover
+ Impulse Transverse Delay

It's defined right there on the page:

DC Sparkover 100 V/s (slow rate of rise of voltage)
Impulse Sparkover 100 V/?s (fast rate of rise of voltage)
Impulse Sparkover 1000 V/?s (very fast rate of rise of voltage)
Impulse Transverse Delay 1000 V/?s (time to fire with very fast rate of rise
of voltage?)
 
DC Sparkover 100 V/s (slow rate of rise of voltage)
Impulse Sparkover 100 V/?s (fast rate of rise of voltage)
Impulse Sparkover 1000 V/?s (very fast rate of rise of voltage)
Impulse Transverse Delay 1000 V/?s (time to fire with very fast rate of rise
of voltage?)

I never use a GDT so I have a hard time to understand the word
literally. I guess the question should be: what is the definition of
Sparkover, Impulse Sparkover and Impulse Transverse Delay for
non-engineer?

Thanks

"?s" should read uS or microsecond or millionth of a second. A rate of rise
of voltage of 100 volts per second is quite slow - if it was a lamp you
would see it change.

A rate of rise of voltage of 100 volts per millionth of a second is very
fast.

A rate of rise of voltage of 1000 volts per millionth of a second is very
fast indeed - in one second you go from zero volts to 1000,000,000 volts
(one billion volts).

I hope this helps.
