Flickers (Momentary Power Outages)
Signs of power disturbance problems
Most digital clocks and electronic equipment are extremely sensitive to momentary power outages. These outages can result in
- Digital clocks and displays flicker.
- Lights flicker.
- VCRs lose programming.
- TV or computer screen images shrink.
Why the devices fail
Momentary power outages as short as one second can cause microprocessor-operated equipment to lose their random access memory (RAM). RAM is the computer memory where current work or active programs are stored.
Examples of RAM chip functions for two common household devices:
- VCR: programming function and station settings
- Digital Clocks: time settings and alarm settings
Causes outside the home
The most common causes of flickers are
- weather - lightning, wind or rain
- objects or animals contacting the power lines and
- damage to underground electrical equipment.
An uninterruptible power supply (UPS) is one device that can help protect your sensitive electronic equipment from power variations.
Uninterruptible power supply (UPS)
A UPS switches the computer over to a battery system during a power loss, and can provide up to 15 minutes of continuous power to your computer.
