Diagnosing Power Problems for Businesses in Raleigh-Durham, NC
Protect your critical systems from costly power disruptions with expert power quality diagnosis and UPS protection solutions from PTG's experienced team serving the Research Triangle Park area.
The Hidden Cost of Poor Power Quality
Most businesses in Raleigh, Durham, and the Research Triangle Park area don't realize that power quality issues are silently damaging their IT infrastructure every single day. These problems go far beyond occasional blackouts and lightning strikes.
Computers and sensitive electronics are extraordinarily vulnerable to their power environment. While most business owners are aware of the need to protect against obvious threats like lightning strikes and utility outages, the reality is far more concerning. The electrical environment in which most computers operate is significantly more problematic than commonly understood.
Final data from a comprehensive five-year survey of power quality in North America conducted by National Power Laboratory reveals a startling truth: the average computer site experiences 289 disruptive or destructive power disturbances per year. That's nearly one power problem every single day. Even more surprising, the most noticeable types of problems—blackouts and lightning strikes—account for less than 12% of these events.
The majority of power disturbances are under- and over-voltage conditions and electromagnetic interference—disruptions that are nearly impossible to detect with the naked eye but can cause devastating damage to your business operations. A more recent study by IBM demonstrated that a typical computer is subject to more than 120 power problems per month. The effects of these power problems range from subtle issues like keyboard lockups and hardware degradation to dramatic failures including complete data loss or burnt motherboards.
For businesses across Raleigh, Durham, Cary, and the entire Triangle region, this represents thousands of dollars in potential losses from downtime, data recovery costs, premature hardware replacement, and lost productivity. The utility companies simply cannot provide the clean, consistent power demanded by today's sensitive electronics, and you are ultimately responsible for the health and safe operation of your equipment.

10 Warning Signs of Power Problems
If your computer systems exhibit two or three of these symptoms regularly, you should seriously consider implementing proper power protection. Each symptom indicates specific power quality issues that can damage equipment and disrupt operations.
Flickering Lights
While most people recognize flickering lights as power-related, they often dismiss these brief flickers as inconsequential. However, computers operate in a world where milliseconds count. A voltage sag lasting just 17 milliseconds is sufficient to crash a network. If your workstation shares an office with your file server, you may notice the server locking up after light flickers, but remote users may never make this connection.
Recommended: Level 5-9 UPS for servers, Level 3 for workstationsData Transmission Errors
Errors in data transmission between network nodes are extremely common, yet few technicians recognize power problems as the cause. Ground loops between devices linked by data cables can create voltage differentials that scramble data or even damage I/O cards. Electromagnetic interference (EMI) from fluorescent lights, radio transmitters, or computer power supplies can also disrupt communications between workstations, servers, and peripherals.
Recommended: Level 5-9 UPS with single grounding pointSystem Lockup
Random system crashes and unexplained freezes are often signs of low voltage sags or subcycle power failures starving logic circuits of necessary voltage. Logic chips operate on just 5 volts DC with tight tolerances—when voltage drops below 4.75 volts, RAM errors increase dramatically. NPL and Bell Labs data show voltage sags are the most common type of power problem. Some cheap Level 3 UPS systems can actually cause logic voltage drops during transfer, measuring as low as 3.5 volts in laboratory tests.
Recommended: Level 9 UPS (no transfer time) or quality Level 5 UPSPremature Component Failure
When I/O cards, motherboards, power supplies, or other vital components suddenly fail without apparent reason, the failure is often incorrectly blamed on manufacturing defects. In reality, rigorous quality control makes built-in defects rare. The true cause is typically latent chip damage from high voltage spikes, line noise, or harmonic distortion. Lightning and other spikes don't always cause immediate failure—delicate conductive traces can be weakened and fail weeks or months later when the damaging event has been forgotten.
Recommended: High-quality UPS with UL 1449 surge suppressionHard Drive Crashes
While less frequent than in the past, hard drive crashes still occur and power problems are often to blame. Sudden power loss during read/write operations is especially dangerous—drive heads can drop precipitously onto the disk, damaging the magnetic medium and creating bad sectors. If this damage occurs in critical areas, complete disk boot failures may result. Modern drives are more resilient, but the risk remains significant without proper protection.
Recommended: Level 3-9 UPS for orderly shutdown capabilityCMOS Corruption
Many users have experienced the horror of turning on their computer to find it suffering from amnesia—no longer remembering drive configurations, monitor types, or memory amounts. Modern systems store vital configuration data in CMOS and EPROM chips. High-voltage impulses can scramble this data, forcing complete system reconfiguration from scratch. CMOS chips are also vulnerable to electrostatic discharge (ESD)—those nasty shocks on dry days that can reach several thousand volts, enough to wipe ROM chips clean.
Recommended: High-quality surge suppressors and ESD protectionHarmonics Issues
If your network behaves strangely as more workstations power up, harmonics may be the culprit. Harmonics appear as current or voltage distortions on oscilloscopes. Ironically, computers themselves are major harmonic sources because their power supplies draw current in isolated gulps instead of smooth sine waves. When many network devices share the same circuit, harmonic content builds as devices turn on, causing increasingly erratic behavior as more workstations operate simultaneously.
Recommended: Level 9 UPS or FERRUPS with ferroresonant transformerModem Transfer Problems
Power problems can cause modem uploads and downloads to abort frequently or generate high rates of error messages. High-frequency spikes or impulses traveling on power lines can couple into phone lines, which rarely have any shielding protection. These signals are then interpreted by receiving modems as bad data blocks, causing transfer failures and frustrating communication problems that seem unrelated to power quality.
Recommended: UPS with phone-line surge protection jacksWavering Monitors
If displays flicker, waver, or dance, it could signal larger power problems affecting your entire network. Voltage sags make monitor displays shrink noticeably. Wavering displays can also indicate strong electromagnetic fields near the monitor. Either situation does more than disrupt your screen—they cause RAM errors, scramble data, and contribute to component failure throughout your systems. What appears as a simple monitor issue often indicates widespread power quality problems.
Recommended: Level 5-9 UPS or FERRUPS with voltage regulationDisk Write Errors
Hard and floppy drives, as the only moving parts in your network, are especially vulnerable to power aberrations. Beyond sudden power loss and RAM errors from low logic voltage, bad power affects disk rotation speed. Proper drive access depends on correct rotation rates—undervoltages cause drives to attempt reading or writing data in wrong sectors. The result can be lost data, garbled information, or complete drive failure requiring costly data recovery services.
Recommended: Level 5-9 UPS with voltage regulationProven Results for Triangle Area Businesses

Frequently Asked Questions
What is the difference between Level 3, Level 5, and Level 9 UPS systems?
Level 3 UPS systems provide basic battery backup and surge protection suitable for workstations and non-critical equipment. Level 5 UPS systems add voltage regulation and buck-boost transformers to compensate for voltage sags and swells. Level 9 UPS systems offer the highest protection with true online double-conversion technology that provides zero transfer time and complete isolation from power line problems, making them ideal for critical servers and network infrastructure.
How much does a UPS system cost for a typical small business?
UPS system costs vary widely based on protection level, capacity requirements, and number of devices. Basic Level 3 systems for individual workstations start around $100-300, while Level 5 systems for small servers range from $500-2,000. Enterprise Level 9 systems for critical infrastructure typically cost $2,000-10,000+ depending on capacity. PTG provides free consultations to assess your needs and recommend cost-effective solutions that match your budget and protection requirements.
How long will a UPS keep my systems running during a power outage?
Runtime depends on UPS battery capacity and the power draw of connected equipment. Most UPS systems are designed to provide 5-30 minutes of runtime—enough for an orderly shutdown or for brief outages to resolve. For extended runtime requirements, PTG can design systems with additional battery packs or integrate UPS systems with backup generators for hours of protected operation.
Can power problems really cause that much damage to computer systems?
Absolutely. Studies show the average computer experiences 289 power disturbances per year, with IBM research indicating 120+ problems per month. While dramatic failures like fried components are obvious, most damage is cumulative—voltage sags weaken circuits over time, harmonics cause premature component failure, and EMI corrupts data. The National Power Laboratory survey showed service calls dropped 82% after UPS installation, demonstrating the significant impact of power quality on system reliability.
Do I need separate surge protection for phone and data lines?
Yes. Power surges can travel through phone lines, network cables, and modem connections, bypassing your main power protection. Many quality UPS systems include phone line protection jacks. For comprehensive protection, PTG recommends surge suppressors on all data cables and using UPS systems with single grounding points for both electrical and data connections to prevent ground loops.
