The damage caused by power problems to computers, networks and othersensitive
equipment can vary from a small disruption to complete equipmentfailure and
destruction. Different products have been developed to deal withthe specific
power problems shown in the diagrams below.
|
 |
CLEAN POWER
This is the ideal mode for all electrical equipment.
|
 |
SURGES
Power surges can result in permanent damage to hardware and other
electrical equipment.
Suggested solution: powerline conditioner or UPS with voltage regulation.
|
 |
SAGS/BROWNOUTS
These are short term, low voltage brownouts, created by large loads,
lightning,utility switching or equipment failure. Sags/brownouts
cause hardwarecrashes and occasional hardware damage.
Suggested solution: powerline conditioner or UPS with under and over voltage protection.
|
 |
SPIKES
Also called transients or instantaneous surges. Spikes cause data
corruption,data lockups and significant hardware damage.
Suggested solution: UPS with surge suppressor, mains spike or filter.
|
 |
RF NOISE
Creates a rough and jagged sinewave. RF noise can even be generated by
normal computer operation. It causes keyboard lockups, program freezes
and data corruption.
Suggested solution: UPS and noise filter or RF mains filter.
|
 |
WAVEFORM DISTORTION
Most common is the harmonic distortion, which causes a doubling of
the normal sinewave. This condition can be triggered by factory
equipment or utility power.
Suggested solution: true on-line double conversion UPS.
|
 |
FREQUENCY VARIATIONS
Mainly caused by back up generators taking over from utility power. Only on-line
UPS systems can rectify this problem.
Suggested solution: true on-line double conversion UPS.
|
 |
COMPLETE OUTAGE/BLACKOUT
Described as 0 volts condition for longer than half a cycle. Unprotected
networks suffer badly during an outage.
Suggested solution: true on-line double conversion UPS.
