This brings up a point I've often considered...
Is grid damage resulting from over-drive primarily the result of
instantaneous high Ig, or is it more from a combination of both high Ig and
duration? It would seem that if a grid is relatively immune to short bursts
of high Ig, then a fast-acting fuse would be appropriate. On the other
hand, if most damage to the grid occurs very quickly, then one would
probably want fast-acting, electronic protection.
