What Is a Surge Protector?

Surge protectors are a good investment whether you’re wanting to expand your existing outlet configuration or provide an extra buffer between your sensitive electronics and the outside world.

Navigating the myriad of options, with their vast price ranges and features, can be overwhelming. It’s challenging to discern the genuine quality products from those that are all flash and no substance.

The purchase of a surge protector is a common component of every computer system build. Most designs have one clear purpose: allowing you to charge many devices from a single wall socket.

This is a practical tool because of the many components that together build up a computer system.

A surge protector is a dual-purpose, portable appliance. The first is to allow for the use of a single outlet for charging several devices.

More importantly, surge protectors serve as a shield for your precious electronics, like TVs and PCs, against the devastating impact of high voltage spikes. These spikes are brief, yet can significantly exceed safe electrical current levels.

A Surge Protector: How Does It Operate?

Common surge protectors simply continue to supply power to the devices hooked into them, as if nothing had happened. In the event that the voltage becomes too high, the protector will channel the excess current into the grounding wire of the outlet.

It is common practice to have grounding wires arranged in parallel with the live and neutral wires. They provide as an alternative channel for electricity to take if the normal system of hot and neutral wires fails.

To What Extent Do Surges Differ from Spikes?

A surge is defined as a sustained rise in voltage that lasts for longer than three nanoseconds. A spike is a transient rise in voltage that lasts for only a few ns. That’s the key distinction, right there. However, if the surge is strong enough, the damage done to a machine in those nanoseconds (billionths of a second) can be severe.

The Most Common Reason For A Spike Or Surge

Although lightning strikes are extremely rare, they are one of the most commonly cited explanations. Powerful appliances like air conditioning units, elevators, and freezers are more often to blame. In order to turn on and off, their compressors and motors use a lot of power.

During switching, it causes transient yet intense power demands, disrupting the normally constant voltage flow. Usually, the electrical system of the structure takes the hit, and if it isn’t safeguarded, the damage might be instantaneous or slow to appear over time.

Power surges can be caused by many different things, but the most common ones include damaged wiring, broken utility equipment, and fallen power lines. Numerous potential failure spots exist inside the intricate network of transformers and wires that supplies your houses with energy, increasing the likelihood that a power surge will occur at some time.

The Excessive Use of Surge Protectors: A Problem to Be Solved

Pushing our hose analogy further, excessive pressure could burst a hose. Similarly, electrical cables and devices can burn or degrade over time under the strain of electrical overload, although they don’t literally explode.

Surge protectors prevent damage to electrical components by releasing pressure in the hose (your home’s cables) when it becomes too high. They require specialized parts to make this happen.

Adjusting to Tension

To what end does all that force, or surplus electrical energy, go? Surge protectors work like a pressure-sensitive valve, redirecting excess energy when the voltage rises over a specific threshold. When the voltage is appropriate, current flows freely; however, when a spike or surge occurs, the device quickly activates and diverts the excess.

Metal oxide varistors (MOV) and gas discharge arrestors are commonly employed in surge protectors to handle this pressure, allowing electrical equipment to continue functioning while channeling excess energy to grounding wires.

Need for Multiple Layers of Security

Surge protectors are designed in such a way that you require all three of the following categories to be adequately protected, or at the very least Type 2 and Type 3 devices:

Type 1: Whole House Protection Installed between the power lines in the street and your meter.
Type 2: Whole House Protection Installed between your meter and breaker box.
Type 3: Point-of-Use Smaller protectors at wall outlets where you plug-in appliances.

Isn’t that overkill?

Might this seem like too much? Actually, it’s necessary. The finest whole-house surge protectors can’t catch everything. Minor voltage excesses, capable of leaking up to 15% of your voltage, remain a threat, not to mention the power spikes originating from within your own home. These devices help mitigate surges from external sources like power providers or malfunctioning transformers.

The many surges caused by your home’s equipment, such as the switching on and off of your air conditioner or refrigerator, are not protected against.

It All Depends on Your Foundation

Even with a surge protector, older homes with ungrounded outlets or incorrect wiring and grounding will still experience power fluctuations. If excess power cannot safely leave the system, even the finest surge protector will be ineffective. This is accomplished by grounding.

Grounding problems in the home should be fixed as soon as possible to prevent expensive damage to electronics and the need to replace expensive components.

The following are examples of components and characteristics found in surge protector devices:

This device is an AC power transformer with an iron core. But it can’t handle spikes in pressure.
It is a Zener diode that is frequently used with a voltage fluctuations suppression diode to provide further protection against common circuit spikes.
A surge protector may shield your electronics from external and internal surges in the event that your circuit breaker is tripped or a fuse bursts.
Using a low pass filter to absorb spikes, and by accepting power from sources other than the battery, it provides a constant stream of electricity with no interruptions.
An MOV, or metal oxide varistor, is a thermally fused component that reduces voltage by a factor of three to four over conventional current. In a similar vein, MOV connections prolong service life and hence boost current capacity. MOVs will eventually self-destruct if they are subjected to many big transients or a large number of tiny transients.

Next, we’ll discuss temporary surge protection. It does this by either blocking the current or shorting it out in an effort to keep the voltage at or below the device’s safe operating range.

Using an inductor, which prevents a spike in current, you may achieve the same effect. Also, capacitors prevent a rapid drop in voltage, whereas spark gaps, Zener-type semiconductors, and MOVs short off the circuit when a particular voltage is reached. Multiple components may be used by certain surge protectors.

Surge protectors for the home may be available in both plug-in power strips and standalone outdoor units.Nowadays, a home’s electrical outlets require a total of three wires: the line wire, the neutral wire, and the ground wire.

Due to situations like lighting where both the cable and neutral might experience high voltage rise that need to be shorted to ground, many protectors now connect to all three in pairs.

Securing a high-quality surge protector, along with a UPS battery, is crucial for safeguarding your home against these risks. While various suppliers offer these essential tools, Schneider Electric stands out for its reliability and performance.

In order to safeguard the system against over or under voltage, they have incorporated a wide variety of surge protection devices.

Damage can occur quickly to an electrical gadget if it is plugged into an outlet without a surge protector. Use a surge protector to shield your electronics from lightning and power spikes; they’re cheap and simple to set up. Even in the long run, they prove useful. Use of a surge protector can increase the useful life of your electrical devices.
