Lightning arrester vs surge arrester: which one do you need for better electrical protection

Image
Lightning can damage a building and the electrical equipment inside it. These risks need different types of protection. An ESE lightning arrester is part of an external lightning protection system. A surge arrester, or SPD, protects electrical circuits and connected equipment from transient overvoltage.   Some buildings may need both. Feature ESE lightning arrester Surge arrester / SPD Main purpose Protects the structure from direct lightning strikes Protects electrical circuits and connected equipment from transient overvoltage Installation Outside the building Inside the electrical distribution system Protection path Down conductor and earthing system Diverts surge current through the SPD to the earthing system Typical location Roof, mast or other suitable high point Main or sub-distribution boards Protects ...

How can a type 2 surge protection device protect your electrical equipment from surges

Image
  A voltage surge can last for only a few microseconds, yet it can damage control panels, electronic equipment and other connected loads. Lightning-induced disturbances and switching operations can create these sudden voltage rises. A surge protection device spd helps limit that voltage and reduce the stress reaching downstream equipment.   A Type 2 surge protection device protects electrical equipment by limiting transient voltage and diverting surge current away from downstream circuits. It is commonly installed at distribution boards to reduce the surge energy reaching connected equipment such as control panels, automation systems and electronic devices. What is a Type 2 surge protection device? A surge protection device type 2 is installed in low-voltage distribution systems to limit transient overvoltage. It is commonly fitted at a distribution board after the incoming protection, protecting circuits and equipment further down the installation.   Axis offers Ty...

How to choose the right lightning arrester manufacturer: 10 things to check before you buy

Image
  A quotation can tell you what a lightning arrester costs. It cannot tell you whether the product has been properly tested, whether its claimed protection radius suits your structure, or what technical support will be available after installation. That is why the ese lightning arrester price should never be the only basis for selecting a supplier. The right lightning arrester manufacturer should be able to show verified testing, clear technical specifications, applicable standards, installation support and long-term product support. Price matters, but it should come after these checks.   Before comparing numbers, check these 10 factors. What to check Why it matters Product quality Helps assess materials, construction and manufacturing consistency ESE technology Confirms the technology and claimed performance Testing Shows whether performance claims are supported by test evidence ...

How to choose the right surge protection device (SPD): complete selection guide

Image
  Choosing a  surge protection device (SPD)  isn't simply about picking the highest kA rating. The correct selection depends on the electrical system, installation point, expected surge exposure and equipment being protected. IEC 61643-11:2025 sets requirements for low-voltage AC SPDs, including performance, safety and testing.   In simple terms, the right SPD depends on where it will be installed and what it needs to protect. For many distribution-board applications, a  surge protection device Type 2  is commonly used, while Type 1, Type 1+2 and Type 3 devices may be needed at other points in the system. Start with the protection point SPD type Where it is used Main purpose Type 1 Main incoming supply Handles high-energy surges, including lightning-related exposure Type 1+2 Main distribution point Combines Type 1 and Type 2 protection Type 2 ...

ESE lightning arrester vs conventional lightning rod: Differences, benefits, and applications

Image
  If you are planning a new building, chances are you will come across two choices for lightning protection: an ESE lightning arrester and a conventional lightning rod. They may look similar at a glance, but they are designed for distinct conditions.   But once you understand how each one functions, selecting the correct system becomes much easier.   Here's how they compare. ESE lightning arrester vs conventional lightning rod Feature ESE Lightning Arrester Conventional Lightning Rod How it works Creates an early upward streamer to intercept lightning sooner Waits for lightning to strike before carrying it safely to the ground Protection area Covers a larger area Protects only the nearby structure Number of units needed Usually fewer Usually more Installation Faster for large sites Better suited for smaller build...

Type 1 vs Type 2 vs Type 3 surge protection devices: Which SPD is right for your electrical system

Image
 You may never notice a power surge, but your electrical equipment certainly will.   A single surge can happen in a fraction of a second. Sometimes it's caused by lightning or by electrical equipment inside the building starting or stopping. Either way, that sudden spike in voltage can shorten the life of your electrical system. Hence, surge protection is a standard part of modern electrical installations. The only question is which surge protection device (SPD) is the right one for your system. Let us find out! Type 1 SPD: Where is it used? Think of a Type 1 SPD as the first line of defense. It is installed at the main electrical service entrance. Its job is to handle very large surges, especially those caused by direct or nearby lightning strikes, before they propagate through the rest of the electrical system.   If your facility is in a lightning-prone area or has an external lightning protection system, a Type 1 SPD is usually the right starting point...

How to choose a reliable lightning arrester manufacturer and avoid frequent system failures

Image
 Volatile storm seasons pose a serious risk of catastrophic insulation failure for industrial facilities. If your external interception terminals fail to stop a strike, thousands of amperes can surge straight into digital controllers, destroying hardware and causing major downtime.   Working with a certified, experienced  lightning arrester manufacturer  is the best way to keep your systems online, stay compliant with regulations, and protect your critical infrastructure.   Verifying international certifications, compliance, and testing A dependable  lightning arrester manufacturer  never relies on unverified product claims. Industrial buyers should verify that air terminals possess ISO 9001 Quality Management Systems and full IEC compliance. High-quality hardware must undergo type-testing in accredited laboratories, including high-voltage impulse testing, mechanical tensile strength testing, and environmental aging testing.   Look...
