Solid state power supplies are protected from medium surge voltage using
:
Zinc-oxide-based
varistors
Cermet
resistors
Metal
glaze resistors
Silicon-carbide
varistors
Zinc-oxide-based
varistors
Zinc-
Oxide based varistors (ZnO)- The surge arrestor which uses Zinc-oxides
semiconductor as a resistor material known as a metal oxide surge arrestor or
ZnO varistor. The diverter provides protection against all type of AC and DC
fault.
Solid
state power supplies are protected from medium surge voltage using Zinc oxide
based varistor.
Hence,
the correct option is (A).
