Introduction
When power fails, the cost is more than just inconvenience—it’s lost data, halted operations, safety risks, and damaged reputations. Yet, what’s often overlooked is that many of these failures are preventable.
At KEMET Engineering, we believe that preventive maintenance is not just a service—it’s a critical part of system reliability. Whether it’s UPS systems, inverters, rectifiers, or measurement instrumentation, routine maintenance ensures longevity, compliance, and peace of mind.
1. The True Cost of Downtime
According to industry studies, even a few minutes of unplanned power interruption can cost thousands—or even millions—for industries like data centers, healthcare, and manufacturing.
💡 Statistic: Data center outages average $8,851 per minute in losses (source: Uptime Institute).
And yet, most failures could be avoided with proactive inspection and care.
2. What Preventive Maintenance Really Involves
It’s more than replacing parts. A solid preventive maintenance program includes:
- Battery testing & health monitoring
- Visual inspections for wear, corrosion, heat damage
- Firmware updates for smarter system behavior
- Thermal imaging to detect unseen electrical risks
- Load testing to confirm system capacity under stress
- Cleaning & cable tightening for reliability and safety
This applies across UPS systems, rectifiers, inverters, and frequency converters—especially in harsh or high-demand environments.
3. Best Practices from the Field
International guidelines (e.g., NFPA 70B, IEEE 1188) recommend preventive checks at regular intervals.
Our own best practice at KEMET involves quarterly system inspections, backed by smart monitoring tools (like those found in DEWEN’s IoT-enabled UPS systems), which allow remote diagnostics and predictive alerts.
4. Benefits That Go Beyond Uptime
✔ Extends the lifespan of critical power infrastructure
✔ Reduces emergency repair costs
✔ Improves safety and reduces insurance risk
✔ Maintains compliance with regulatory and safety standards
✔ Supports sustainability by reducing premature replacements
5. KEMET’s Lifecycle Support Philosophy
KEMET Engineering provides more than just systems—we support the full lifecycle. From installation and commissioning, to routine inspections, system upgrades, and on-site support, we ensure your energy infrastructure performs at its peak.
💡 Through DEWEN™, we deliver smart UPS systems that enable AI-based predictive maintenance, reducing manual checks and preventing failures before they occur.
Conclusion
Power reliability is no longer a luxury—it’s a business essential. Preventive maintenance is the key to avoiding breakdowns, protecting investments, and ensuring operational continuity.
Whether you’re running a data center, a hospital, or a factory floor, the question isn’t if you should maintain—it’s how soon you can start.
