In this article, we will overview what you ought to know about a surge protection device. So, if you need to know where to start, keep reading to learn how SPDs can make all the difference.

What is a Surge Protective Device?

A Surge Protective Device (SPD) is your initial safeguard against sudden and disruptive spike in electrical currents. Such transients may result from causes like lightning, variations in power supply, or turning on/tripping off large electrical loads. When there is no surge protection, these sudden voltage peaks can degrade, damage, or even destroy crucial electronics. It will also reduce the equipment’s lifespan or bring an entire system to its knees. They are a basic necessity for the protection of the various gadgets in our homes and the industry. It distributes the current and allows systems to continue running without fear of blackout.

Types of Surge Protection Devices

There are three categories of Surge Protective Devices in the market. Opt for the one that fits your needs. Type 1 SPD: Its placement location is the point of electrical entry to a building, like the main distribution box. They protect the system from external rise in voltage, such as lightning strikes. Type 2 SPD: Its placement area is sub-distribution boards to shield against surges found in the building, residential/commercial. Type 3 SPD: The perfect placement for type 3 is near the protected load or individual appliances. It works only in addition to Type 2 SPDs. Upon the installation of multiple SPDs, ensure they synchronize in proper coordination.

How Do Surge Protection Devices Work?

Surge Protection Devices (SPDs) provide the ultimate protection to electrical systems and devices. When a surge, like lightning or power outages, causes the voltage in an electrical system to spike, the SPD steps in. SPD detects the surge and immediately directs the excess voltage away from your devices and safely toward the ground. In this way, the surge doesn’t reach and damage your equipment. SPDs typically use two main components to handle this process: Metal Oxide Varistors (MOVs) and Gas Discharge Arrestors (GDAs). Once the SPD handles the surge and the voltage levels return to normal, the SPD resets. It then goes back to the monitoring phase of electrical flow, ready to handle future surges.

When to Use Surge Protection Devices?

SPDs work as shield providers to electrical systems. Therefore, every area needs its installation to protect the systems from voltage surges.

Residential Settings

SPDs safeguard home electronics from high voltages resulting from lightning or instability in power companies. In severe weather conditions, SPDs in connection with the electrical panel serve the electrical circuit of the whole house.

Commercial Buildings

Businesses such as offices and data centers require computers, servers, and checking machines. They assist in avoiding downtimes, data loss, and equipment damage in the case of power surges.

Industrial Environments

Factories have heavy machinery, which creates some power fluctuations during the work. SPDs safeguard control panels and circuits, safety circuits, and telecommunication equipment so they can run at all times. For this reason, SPDs are important and provide safety and reliability in the industrial, commercial, and residential categories.

How Do I Know if I Need Surge Protection Devices
