Lightning rods protect buildings—but do they protect… electronics? Time for Part 2 of our training!

Recently, we introduced you to the world of surges and direct lightning strikes (if you missed the first episode, you’ll find the link in the comments!👇). Today, we’re taking it a step further by tackling the issue responsible for nearly 90% of damage to modern electronics.

We’re talking about indirect lightning effects (LEMP).

In this new episode on our YouTube channel, we explain why protecting a building can, paradoxically, harm the installation.

In this video, you’ll learn:

What the “lightning rod paradox” is and how to avoid it
The right-hand rule in practice – what you need to know as a designer or installer
How to effectively protect devices from electromagnetic impulse (LEMP)

This training is a must-watch for anyone responsible for the reliability of LAN, CCTV, or automation systems.

Watch Part 2 of the training on YouTube: https://youtu.be/gOih40aBLbg

Remember, all recordings and additional materials are also available in the new “Training” section on our website: https://ewimar.com/

Has modern technology become too fragile to withstand a storm?

Modern electronics are far more susceptible to damage than systems from decades ago. This is a direct result of miniaturization. Although devices are smaller and faster, their physical resistance to power surges has dropped dramatically for several key reasons:

👉 Limited thermal resistance: Smaller components overheat instantly when exposed to excess surge energy.
👉 Delicate PCB structure: Extremely narrow copper traces in densely packed circuits can literally vaporize under the influence of surge current.
👉 Lower operating voltages: The drop in nominal voltages in digital circuits means that even minor voltage spikes become fatal for communication interfaces.
👉 Standard ESD protection is insufficient: Effective protection systems require high-power components, for which there is no space inside devices. Furthermore, such protection must have a properly designed energy dissipation path to ground, which internal electronic circuits typically do not provide.

At Ewimar, we design surge arresters that serve as an essential protective barrier for miniaturized electronics. For example, the PTF-51-EXT/PoE/Micro/T surge arrester (https://ewimar.com/miniature-surge-protector-for-lan-network-protection-ptf-51-ext-poe-micro-t-with-heat-shrink-cover.html) and PTF-51-EXT/PoE/T (https://ewimar.com/lan-network-surge-protector-series-ext-ptf-51-ext-poe-t-with-heat-shrink-cover.html) have been effectively protecting our customers’ outdoor cameras for years. Our devices absorb the impact of surges, protecting the sensitive components of CCTV, intruder alarm, and LAN systems from costly failures.

If you’d like to learn more about these threats, we invite you to watch the first part of our training series on YouTube (https://youtu.be/OVJui6f8XEw), where we analyze in detail how these threats impact modern infrastructure. In upcoming lessons, we’ll explore methods for preventing damage to modern infrastructure.

We’ve launched a new training series dedicated to threats affecting telecommunication and low-voltage installations. 👇

The materials were prepared for system designers, installers, and professionals responsible for the reliability of telecommunication infrastructure. In the upcoming episodes, we will discuss the most important risks faced by modern installations and present practical solutions that help protect equipment and critical infrastructure.

We will also introduce the technologies used in our products that increase the safety and resilience of installations.

In the first episode you will learn:
• what electrical surges are and the main types of surges
• why a direct lightning strike is one of the most serious threats to installations
• what damage can occur when lightning hits a building or a power line
• how lightning discharges affect LAN networks, CCTV systems, and security installations

The video is also available here on Facebook, while the next parts of the training will be published on our YouTube channel. For our customers’ convenience, we have also created a “Training” section on our website where you can quickly find all the recordings:
https://ewimar.com/

Make sure to follow and subscribe so you don’t miss the upcoming episodes, where we will explain in detail how to protect installations and how to select the right surge protection solutions.

PTF-64-EXT/PoE – 4-channel surge protector for Gigabit LAN network.

In LAN networks and monitoring systems, as much as 90% of electronic failures result from surges induced by atmospheric discharges near the installation. To ensure reliable device protection according to the PN-EN 62305-4 standard, it is essential to use surge protectors at the boundary of LPZ zones.

PTF-64-EXT/PoE from Ewimar offers advanced signal and PoE power protection, as well as:

• 3-stage protection: gas arrester, TVS, MOSFET – effectiveness 1kA (10/350 μs) and 2.5kA (8/20 μs) per conductor, residual voltage < 8 V.
• Full PoE and Hi-PoE compatibility: standards 802.3 at, af, bt (max 60 W/channel).
• Multiple use: the protector does not wear out during standard operation and responds multiple times to surges.
• Certification: tests compliant with PN-EN 61643-21 standard.

In practice, the device is installed near the switch in combination with single-channel protectors mounted at cameras, which ensures comprehensive network protection against surges induced on LAN segments. The excess energy generated by the surge is instantly diverted to grounding, protecting sensitive system components and ensuring continuous operation of the installation. Thanks to compatibility with 19’’ Rack enclosures, it is possible to neatly install several modules in one cabinet, maintaining order and full system functionality.
Protect your network and equipment from surges – PTF-64-EXT/PoE from Ewimar.

Do you have lightning protection installed? This is a very important step towards building safety. However, it’s worth remembering that it does not fully protect electrical and electronic devices operating in the installation.

A lightning protection system safeguards the structure of the building but does not eliminate indirect surges. Voltage spikes can occur even when a discharge happens nearby—through power or signal lines. These are one of the most common causes of electronic damage.

That’s why a key supplement to protection is surge protection devices 𝗦𝗣𝗗. They limit dangerous voltage spikes in the installation, and their effectiveness depends on properly executed grounding, which allows safe dissipation of energy away from protected devices.

👉 Want to truly protect your electronics and ensure stable operation of your installation?
Combining lightning protection, 𝗦𝗣𝗗, and proper grounding is the only effective solution.
