In today’s around the clock business environment, downtime just isn’t an option. The ability to ensure that computer systems and mission-critical applications are up and running at all times is vital. The most frequent cause of system-wide failure stems from nine common power problems, all of which can threaten your network’s functionality, as well as your company’s integrity. Downtime – even as a matter of seconds – can carry a staggering price tag. Studies show that businesses can lose $10,000 to several million dollars per minute when networks go down, a steep price to pay when premium power protection is available for a fraction of what you’re spending on your hardware solutions.
One of the most successful means of mitigating the risks associated with power problems in the installation of a Powerware Uninterruptible Power System (UPS). A complete line of UPSs is available featuring three levels of protection: Series 3 Series 5 and Series 9. Also available are products with ferroresonant technology. Depending on which series of UPSs you chose, your equipment will be safeguarded against, three, five or all nine of the most common power problems. |

|
Power failure: A total loss of utility power. Can be caused by lightning strikes, downed power lines, grid over demands, accidents, etc… |
| |
|
|
 |
|
Power sag: Short-term low voltage. Triggered by the start-up of large loads, utility switching, utility equipment failure, lightning and power service that is too small for the demand. Can cause system crashes and hardware damage. |
|
|
|
 |
|
Power surge: Also known as a spike. Short-term high voltage above 100% 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 damage hardware. |
|
|
|
 |
|
Under voltage: Also known as a brownout. Reduced line voltage for extended periods ranging from a few minutes to a few days. Can be caused by an intentional utility voltage reduction to conserve power or heavy loads that exceed supply capacity. |
|
|
|
 |
|
Over voltage: Increased line voltage for extended periods ranging from a few minutes to a few days. Can be caused by a lightning strike. A spike almost always results in data loss and/or hardware damage. |
|
|
|
 |
|
Electrical line noise: High frequency waveform interference. Ca be caused by either Line RFI or ELI interferences generated by transmitters, welding devices, SCR-driven printers and lightning. |
|
|
|
 |
|
Frequency variation: A change in frequency stability, resulting from generators or small co-generation sites being loaded and unloaded. Can cause erratic operation, data loss, system crashes and equipment damage. |
|
|
|
 |
|
Switching transient: Instantaneous under voltage (notch). Normal duration is shorter than spike. |
| |
|
|
 |
|
Harmonic distortion: Distortion of the normal waveform caused by switch-mode power supplies, variable speed motors and drives, copiers and fax machines and other non-linear loads. Can result in communication errors, overheating and hardware damage. |
