Prevention is better than cure
Prevention is better than cure
This is true, not only for people, but also for the “health“ of
your electrical and electronic components and equipment.
Cost-effective strategies demand an investment in surge
protection. Such an investment would only be a fraction
of the amount of possible damage. The shut down of a
manufacturing plant because of the failure of a controller
or the collapse of industrial data transmission can be very
costly. But the signicant overhead in repairing the problem
is not the only factor. You must also take into account the
system down times. The lifespan of your components (mean
time between failure) will also be shortened.
Surge voltages present a signicant danger and this can be
demonstrated in many other ways than the examples given
in damage statistics from property insurers.
All electrical equipment is potentially threatened by
surge voltages: this includes free-standing high-voltage
switching facilities and also electronic micro-components.
For low voltages, this risk is predominant in the elds
of power supply, measure and control technology,
telecommunications, and data transmission. We therefore
work with protective strategies and systems when designing
lightning and surge protection. Only an entire system can
provide effective protection for all areas of power, signals
and data and we offer an ideal form of surge protection for
all these applications elds.
Surge protection has become an area of increasing
signicance. On the one hand, electrical and electronic
components continue to get smaller. On the other hand,
the levels of automation in the industrial and consumer
electronics sectors are continuing to rise.
The safety clearances for insulation decrease as do the
tolerance limits. Electronic circuits function at low voltage
levels of only several hundred volts. Thus surge voltages can
present a signicant danger.
The German “Law on electromagnetic compatibility in
devices” establishes the proper EMC-compliant design and
layout for electrical and electronic devices.
Surge protection is an element of these EMC measures and
implementation of this protection is described in a variety
of IEC/VDE standards. Such measures can also help in
obtaining the CE mark of approval.
To guarantee the safety of consumers, different product
standards offer a method for ensuring a global product
standard.
