On the Time Lag Measurement of Spark in Solid Dielectric

Abstract

Intending to measure the time lag of spark in solid dielectric, the author has uti'ized the same method as was used by the author to measure the time lag of spark in oil.
The solid dielectrics tested are ebonite, bees-wax, presspahn, paraffin, paper, mica and glass.
It can be in fered from the author's observations that:-
1. The time lag of spark in solid dielectric is greater than that in air.
2. The time lag of spark in solid diel ctric depends upon its material.
3. The solid dielectrics as mica and glas seem to have different characters from other solid dielectrics.
4. The time lag of spark in thin solid dielectric is in order of 10-8. sec. under the utilized source.
5. The empirical formula for the time lag of spark is:-
elther t=d2 or t=d√l
