The Correct Option is B
Solution and Explanation
Ceramic insulators are used in electrical applications.
High tension insulators are used where high voltage is involved.
In such applications, the surface condition of the insulator is very important.
If the surface becomes highly charged or contaminated, electrical discharge may occur.
Semiconducting glazes are used on high tension ceramic insulators to control surface conductivity.
They help in distributing electric potential more uniformly over the surface.
This reduces local electrical stress.
It also helps to reduce corona discharge and flashover problems.
Opaque, transparent, and translucent glazes mainly describe optical properties.
They are not specifically used for controlling electrical behavior in high tension insulators.
Therefore, the glaze used on high tension ceramic insulators is:
\[
\text{Semiconducting glaze}.
\]
