Small Power Surges Can Pose Big Risks to Critical Infrastructure
Data-heavy industries such as data centres, telecommunications facilities and financial institutions process millions of data points every second across a complex network of servers and storage systems. While these facilities typically employ sophisticated surge protection for industrial equipment, their operations can still face a significant hidden threat: surge-induced power outages.
When power surges trigger protective systems to cut power, the subsequent outages can lead to major consequences for data-heavy operations. While large-scale power outages are obvious threats, danger can often lie in smaller, more frequent power surges. These seemingly minor voltage fluctuations can trigger protective systems, leading to brief but impactful outages. Over time, these surge-induced interruptions can accumulate, gradually degrading equipment and potentially corrupting critical data.
In this blog, we’ll look at the impact of surge-induced outages on data-heavy industries and how stand-by power solutions, including switchgear power maintenance systems, provide the Power Assurance needed to protect data integrity and prevent equipment damage.
Understanding Surge-Induced Power Loss
When power surges occur, power surge protection systems often trigger automatic shutdowns to prevent equipment damage from high voltage. While this protection is necessary, the impact of this power loss can be wide-reaching for data-heavy operations. These events might last from seconds to hours, depending on the severity of the surge and the time needed to safely restore power.
Why Data-Heavy Industries Are Particularly Vulnerable
Data centres process millions of operations per second. Financial institutions rely on microsecond-accurate timestamps for trading transactions. Telecommunications providers must maintain constant, error-free data transmission. These are all examples of industries that rely heavily on continuous data processing.
Servers, network switches and storage arrays are engineered to perform under specific power conditions. When voltage fluctuates beyond these parameters, even briefly, it can cause subtle but potentially significant issues, such as data corruption and equipment damage. “IT hardware cannot tolerate significant disturbances, such as major voltage sags and swells or the complete loss of power, for more than a tiny fraction of a second,” according to the authors of the Uptime Institute Global Data Center Survey.
Consequences of Unchecked Power Surges
Data Corruption and Loss
The impact of surge-induced outages on data integrity often manifests gradually. Ongoing data operations are stopped abruptly, which can introduce errors in stored data, lead to incomplete writes and corrupt databases. For financial institutions, this might mean lost transaction records, while telecommunication providers could face widespread service disruptions.
Hardware Damage and System Downtime
Sudden power loss can also cause physical damage to electronic components. Modern servers and network equipment require proper shutdown sequences to protect their components. When power is cut abruptly after a surge, these sequences can sometimes be bypassed and potentially lead to hardware damage.
Sensitive components in IT systems can slowly degrade, which might not be immediately apparent, but the effects can compound over time and lead to gradual failure. Organisations face not only immediate hardware replacement costs but also extended recovery periods, lost operational time and potentially damaged client relationships.
Detecting Early Signs of Power Surge Outages
One of the challenges with power surge outages is that damage often goes unnoticed until significant system failures occur. However, there are early warning signs that facility managers and engineers can look out for:
- Flickering lights: This is often one of the first signs of inconsistent voltage levels.
- Unexplained system reboots: If your IT systems are rebooting without any clear cause, it could be due to small power surge outages.
- Frequent error messages: Data corruption caused by outages can manifest as frequent error messages or corrupted files.
- Shortened equipment lifespan: If your servers or networking gear seem to be overheating, failing prematurely or requiring frequent repairs, it may be due to repeated exposure to small voltage spikes and outages.
- Frequent data recovery operations: If your systems are running data recovery procedures more frequently than scheduled, it may be that critical operations are being interrupted by power surges.
Paying attention to these warning signs and conducting regular inspections of your electrical infrastructure can help you catch potential problems before they lead to major failures.
How Stand-by Power Systems Can Help Mitigate Risks
Even with vigilant monitoring of early warning signs, the speed and unpredictability of power surges often means detection alone isn’t enough to protect critical systems.
When power surge protection triggers protective shutdowns, stand-by power systems work together to maintain stable power delivery to critical operations. DC charging systems and battery tripping units maintain live switchgear systems, enabling backup power solutions like UPS to deliver stable power to key processes. This ensures power can be efficiently distributed when needed
This infrastructure enables:
- Controlled shutdowns – by maintaining live switchgear systems, backup power can be properly routed to allow for safe system termination and proper data-saving sequences
- Operational continuity – keeping switchgear systems live ensures immediate power transfer between main and backup power sources, allowing protective mechanisms to function and preventing data corruption during transitions
- Prevention of cascading issues – maintained switchgear readiness helps avoid system restart complications and potential data recovery operations that could compound outage-related damage
