Loadshedding has become a grim reality for South African businesses and households. While the immediate frustration of being left in the dark is well understood, an often-overlooked consequence is the increased probability of electronic, networking, and computer equipment failure. Despite the classic IT meme, โ€œHave you tried turning it off and on again?โ€, the truth is that equipment isnโ€™t designed for constant power cycling. The more frequently devices are powered down and rebooted, the higher the chance of a failure occurring. Add power surges and spikes into the mix, and youโ€™ve got a recipe for disaster. ๐Ÿš๏ธโš ๏ธ๐Ÿ”„

The Risks of Constant Power Cycling ๐Ÿ”๐Ÿ”‹โš™๏ธ

Every time electronic equipment is turned on, it undergoes an inrush currentโ€”an initial surge of electricity required to power up. Over time, repeated exposure to these surges wears down components such as capacitors, power supply units, and even storage devices. Networking gear, routers, and servers are particularly vulnerable, as they are typically designed to operate continuously rather than being switched on and off multiple times per day. ๐Ÿ“‰๐Ÿ’ป๐Ÿ”ง

With each loadshedding cycle, the probability of failure increases. Some devices may not power back on at all after an outage, and others may start behaving erratically due to degraded internal components. ๐Ÿ›‘โš™๏ธ๐Ÿ’”

The Dangers of Power Restoration: Surges & Spikes โšกโš ๏ธ๐Ÿ”Œ

When Eskom flips the switch back on, a surge of power rushes through the grid. These sudden voltage spikes can damage power supplies, fry delicate circuitry, and, in worst-case scenarios, completely destroy electronic equipment. ๐Ÿ”ฅ๐Ÿ’€๐Ÿ’ป

While some may think an Uninterruptible Power Supply (UPS) will solve the problem, most consumer-grade UPS devices are not equipped to handle significant power fluctuations, and they often fail after repeated use. The same applies to surge protectorsโ€”while better than nothing, many are incapable of handling high-energy surges over time. ๐Ÿšง๐Ÿ”‹โš ๏ธ

Mitigating the Risks ๐Ÿ›ก๏ธ๐Ÿ”„โœ…

Since loadshedding isnโ€™t going away anytime soon, businesses and households need to take proactive measures to protect their equipment. ๐Ÿ ๐Ÿข๐Ÿ”Œ

1. Install a Surge Protector at the Distribution Board (DB) โšก๐Ÿ›ก๏ธ๐Ÿ 

One of the most effective ways to mitigate power surges is to install a surge protector directly at the DB. This provides protection at the source, ensuring that all connected circuits benefit from voltage regulation. โš™๏ธ๐Ÿ”๐Ÿ”„

2. Implement a Time-Delay Circuit โณ๐Ÿ”Œโšก

A time-delay switch is an excellent way to reduce the risk of damage when power is restored. Instead of energizing all circuits at once, a time-delay relay ensures that sensitive equipmentโ€”like networking gear, computers, and serversโ€”only powers up after a few minutes. This allows voltage levels to stabilize and minimizes inrush current damage. โฒ๏ธ๐Ÿ”‹๐Ÿ–ฅ๏ธ

3. Use a Manual Load Management Process ๐Ÿ› ๏ธ๐Ÿ’ก๐Ÿ”„

In the absence of an automatic time-delay switch, a manual approach can help. Before loadshedding starts, switch off all circuits except for essential lighting. When power returns, allow the lights to stabilize before manually switching on other circuits. While this can be effective, it is also prone to human error, making an automatic solution far more reliable. ๐Ÿคทโ€โ™‚๏ธ๐Ÿ’กโš ๏ธ

4. Invest in High-Quality Power Protection Equipment ๐Ÿ”๐Ÿ›ก๏ธ๐Ÿ’ฐ

Beyond DB-level protection, businesses should invest in enterprise-grade surge protectors, voltage regulators, and power conditioners. These devices provide an extra layer of security against power fluctuations. ๐Ÿ“Š๐Ÿ”ง๐Ÿ’พ

5. Monitor and Maintain Equipment Regularly ๐Ÿ› ๏ธ๐Ÿ“ก๐Ÿ”„

Frequent power cycles put additional strain on networking and computing equipment. Implementing a proactive maintenance strategyโ€”such as checking power supplies, monitoring logs for signs of degradation, and keeping spares on handโ€”can prevent unexpected failures. ๐Ÿ“‹๐Ÿ’ก๐Ÿ“Š

Wrap ๐Ÿšจ๐Ÿ”Œโœ…

Loadshedding isnโ€™t just an inconvenience; itโ€™s a silent killer of electronic equipment. The repetitive cycle of power cuts and restorations significantly increases the risk of hardware failure. By implementing surge protection at the DB, using time-delay circuits, and investing in quality power management equipment, businesses and homeowners can mitigate these risks and ensure their equipment remains operational for as long as possible. ๐Ÿ โšก๐Ÿ”ง

In short, when it comes to protecting your gear, donโ€™t wait until you hear the dreaded click-click... nothing happensโ€”act now to keep your equipment safe! ๐Ÿšจ๐Ÿ’€๐Ÿ”‹
