Short Term Low Voltage

Cause
Triggered by the startup of large loads
Utility Switching
Utility equipment failure
Power service that's too small for the
demand
Effect
System Crashes
Damage hardware
Solution
Protect your critical
equipment with a UPS!
Power Sag Definition: Power sags involve voltages 80 to 85 percent below normal
for short periods of time (one or more cycles). Possible causes are heavy
equipment being turned on, large electrical motors being started, and the
switching of power mains (internal or utility). A power sag can have effects
similar to those of a power surge, such as memory loss, data errors, flickering
lights and equipment shutoff.
