Fast Response 10D 561k Metal Oxide Varistor Low Clamping Ratio And
No Following-On Current
Metal oxide varistors are key protection devices for power and
electronic systems, directly determining the safety and reliability
of system operation. This book systematically introduces the basic
research, preparation process, performance regulation and
application progress of varistors such as zinc oxide, including
conduction and aging mechanism, microstructure electrical
characteristics, microstructure test and microstructure simulation
analysis, high gradient low residual voltage oxidation The research
progress of varistor ceramics, titanium oxide, tin oxide and other
system varistor ceramics, etc., has established the correlation
between the microstructural characteristics and macroscopic
characteristics of varistors
Electrical characteristics
Varistors remain non-conductive during normal operation. As a shunt
mode device, varistors are often used to suppress line voltage
surges when the voltage across them remains well below their
"clamping voltage". Varistors can fail for two reasons.
Catastrophic failures have occurred due to unsuccessful attempts to
limit very large surges caused by events such as lightning strikes,
where the energy involved is many orders of magnitude higher than
the varistor can handle. Subsequent current flow from the impact
could melt, burn or even vaporize the varistor. This thermal
runaway is due to the lack of uniformity at the junctions of
individual grain boundaries, leading to the failure of the dominant
current path under thermal stress when the energy in the transient
pulse (usually measured in Joules) is too high (i.e. significantly
exceeds the fabrication quotient of the "Absolute Maximum
Ratings"). The potential for catastrophic failure can be reduced by
overrating or using specially selected MOVs in parallel.
