A sphere gap is a type of voltmeter. It contains 2 spheres
one of it is connected to Earth n second is connected to the
point of which voltage is to be measured. The gap between 2
spheres is reduced till a breakdown takes place. After a
break down the gap is measured n the gap is compared with a
standard table.
Eg. if B/D takes place at 2mm then the voltage recorded in
standard table for 2mm is known.
