No Power Problem Definition Cause and Results UPS Solution
1 Power Outage A total loss of utility power Can be caused by a number of events: lightning strikes, downed power lines, grid over-demands, accidents and natural disasters. Standby
Line-interactive
Online
2 Power Sag Short term low voltage Triggered by the startup of large loads, utility switching, utility equipment failure, lightning and power service that’s too small for the demand. In addition to the crashes, sags can damage hardware Standby
Line-interactive
Online
3 Power Surge Short term high voltage With voltages above 110% of nominal, surges can be triggered by a rapid reduction in power loads, heavy equipment being turned off, or by utility switching. The results can potentially damage  hardware. Standby
Line-interactive
Online
4 Brownout Reduced line voltage for extended periods of a few minutes to a few days Can be caused by intentional utility voltage reduction to conserve power during peak demand periods or other heavy loads that exceed supply capacity Line-interactive
Online
5 Electrical Line Noise High frequency Waveform that piggybacks
on the line waveform
Can be caused by either RFI or EMI interference generated by transmitters, welding devices, SCR driven printers, lightning, etc Line-interactive
Online
6 High Voltage Spike Instant and
dramatic increase in line voltage
Can be caused by lightning strikes and can send line voltages to levels in excess of 6,000 volts. A spike almost always results in data loss or hardware damage to unprotected systems Online
7 Frequency Variation A change in
frequency stability
Resulting from generator or small
co-generation sites being loaded and unloaded. Frequency loss, system crashes and equipment damage.
Online
8 Switching Transient Instantaneous
high voltage increase impressed on the power line waveform
Normal duration is shorter than a spike and generally falls in the range of nanoseconds. Online
9 Harmonic Distortion Distortion of
the normal line waveform, generally transmitted by
nonlinear loads.
Switch-mode power supplies, variable speed motors and drives, copiers and fax machines are examples of nonlinear loads. Harmonic distortion can cause communication errors, overheating and hardware damage. Online
