What Are Surge Arresters?

Surge arresters are crucial in data centers, as they protect against overvoltage surges that can damage equipment. They are used in 14 key applications, including power distribution systems, servers, UPS systems, and networking devices. Don’t risk equipment failure – ensure surge protection in your data center.

Definition And Purpose Of Surge Arresters

Surge arresters, also known as surge protectors or lightning arrestors, are devices used to protect electrical equipment from power surges. These surges can occur due to lightning strikes, power grid fluctuations, or switching operations within the electrical system. Surge arresters play a crucial role in safeguarding sensitive electronics by diverting excess voltage away from equipment and into the ground. By limiting the voltage spikes and transient surges that reach the equipment, surge arresters help prevent damage, downtime, and data loss in data centers.

How Surge Arresters Protect Against Power Surges

Surge arresters work on a simple yet effective principle. They employ a combination of metal oxide varistors (MOVs) and gas discharge tubes (GDTs) to redirect transient surges to the ground. When the voltage level in the electrical system exceeds the normal operating level, the MOVs and GDTs within the surge arresters activate. The MOVs, made of semiconductor materials, quickly conduct the excess voltage to the ground, while the GDTs provide additional protection by discharging the surge. This quick diversion of excessive energy helps maintain a stable voltage level and prevents it from reaching sensitive equipment.

Importance Of Surge Arresters In Data Centers

In the fast-paced world of data centers, where processing, storage, and communication of massive amounts of data takes place, the uninterrupted flow of power is critical. Any disruption or damage to the data center’s electrical infrastructure can lead to costly downtime and potential data loss. Surge arresters play a vital role in ensuring the smooth operation and protection of data centers by mitigating the risks associated with power surges. Here are some key reasons why surge arresters are indispensable in data centers:

Factors To Consider When Choosing Surge Arresters

Choosing surge arresters for data centers involves considering various factors to ensure optimal protection. These factors range from the voltage rating and energy absorption capacity to the need for coordination with other protective devices. Additionally, surge arrester applications in data centers can include equipment protection, lightning protection, and protection against transient voltages.

Factors to Consider When Choosing Surge Arresters Voltage ratings and energy absorption capabilities Choosing the right surge arresters for your data center is crucial to protect your equipment and ensure uninterrupted operations. One of the key factors to consider is the voltage rating of the surge arrester. It is important to select surge arresters that can handle the maximum voltage levels expected in your data center. These ratings are typically specified in kilovolts (kV) and indicate the maximum voltage that the surge arrester can safely withstand. In addition to voltage ratings, energy absorption capabilities are equally important. Surge arresters are designed to absorb and dissipate the harmful energy of transient voltage surges. The energy absorption capacity of a surge arrester is specified in joules (J) and represents the amount of energy it can safely handle. Choosing a surge arrester with a higher energy absorption rating ensures better protection against transient voltage surges. Types of surge arresters (movable, non-movable, hybrid) Surge arresters come in different types, each suitable for specific applications. The most common types are movable, non-movable, and hybrid surge arresters. A movable surge arrester is connected to the equipment it protects and moves with it. This type of surge arrester is ideal for mobile or portable data centers where equipment is frequently relocated. A non-movable surge arrester, on the other hand, is permanently installed at a fixed location. It provides protection to a specific area or equipment within the data center. Hybrid surge arresters combine the features of both movable and non-movable surge arresters. They offer the flexibility of mobility, along with the reliability of a fixed installation. Size and form factor considerations The size and form factor of surge arresters are important considerations when choosing the right surge arrester for your data center. In a data center, where space is often at a premium, compact surge arresters are preferred. These surge arresters are designed to occupy minimal space while still providing effective protection against transient voltage surges. Compact surge arresters can be easily integrated into the existing infrastructure without causing interference or congestion. Reliability and warranty options When it comes to surge arresters, reliability is of utmost importance. You need surge arresters that can withstand harsh environmental conditions and operate flawlessly over an extended period. Look for surge arresters that are manufactured by reputable companies and have a proven track record of reliability. Additionally, consider the warranty options provided by the surge arrester manufacturer. A comprehensive warranty not only offers peace of mind but also indicates the manufacturer’s confidence in the product’s quality and durability. Ensure that the warranty covers both the surge arrester and any potential damage caused by transient voltage surges. Installation and maintenance requirements Installing surge arresters in your data center should be a straightforward process. However, it is essential to understand the installation requirements of the surge arrester you choose. Some surge arresters require specialized mounting brackets or additional equipment for proper installation. Consider the availability of these installation components and whether they are compatible with your existing infrastructure. Maintenance requirements are another factor to consider. Ideally, choose surge arresters that require minimal maintenance, such as periodic inspections or simple cleaning. This ensures hassle-free operation and reduces the chances of downtime due to surge arrester maintenance. By considering these factors – voltage ratings and energy absorption capabilities, types of surge arresters, size and form factor considerations, reliability and warranty options, and installation and maintenance requirements – you can confidently choose the right surge arresters for your data center.
