Protecting electronic systems Introduction
Devastating effects
Transient overvoltages can reach magnitudes of up
to 6000 Volts in a well-insulated 230/400 V power
distribution system, over eight times the level
tolerated by many electronic systems.
Although lasting only thousandths or millionths of a
second, without protection they can devastate modern
electronic systems:
disrupting system operations, through data
loss, data and software corruption and
unexplained crashes
degrading equipment components and
circuitry, shortening equipment lifetime and
increasing failures
destroying components, circuit boards and
I/O cards
causing costly and unnecessary system downtime
Protection benefits
Effective transient overvoltage protection can prevent:
lost or destroyed data
equipment damage
repair work - especially costly for remote or
unmanned installations
the high cost of extended stoppages - sales lost to
competitors, lost production, deterioration or
spoilage of work in progress
loss of essential services - fire alarm, security
systems, building management systems
health and safety hazards caused by plant
instability, after loss of control
fire risks and electric shock hazards
Effective protection is achieved through installation of
a coordinated set of Furse Surge Protective Devices
(SPDs), covering incoming/outgoing mains and data
lines and protecting sensitive and critical electronic
systems from damage.
