The possible types of damage are injury to living beings due to step and touch voltage physical damage (fire, explosion, mechanical destruction, chemical and radiological release) due to lightning current effects and failure of internal systems due to lightning electromagnetic impulse (LEMP).

We hope this article will help you understand the clear difference between the conventional lightning arresters and ESE lightning arresters. The ESE lightning arrester does not just protect structure but also the open surroundings too.For the lightning protection of the larger fields or solar parks, the ESE lightning arrester becomes inexpensive considering their protection radius.The larger radius can be protected using the ESE lightning arrester.The ESE system will not hit random objects such as structures, solar panels, electrical or communication line, etc. The ESE lightning arrester system will respond faster when compared to Conventional lightning arresters. Watch the video to understand the difference in detail Generally, the ΔT gets defined as per the area & requirement of the project. At Axis Electrical Components, we have a range of products from the ΔT of 10μs to 60μs.

As per NFC 17-102, the ΔT for an ESE Lightning Arrester should be at least 10μs. The ESE lightning arrester can cover a larger radius compared to a traditional lightning arrester. The response time for ESE IS reduced by storing energy from the ambient electromagnetic field or static charges at the time of the lightning. The main difference between a conventional lightning arrester and an ESE lightning arrester is the response time ( ΔT) taken to ground the lightning strike through the lightning protection system. Hence instead of hitting random objects or the structure of the facility, the lightning bolt will conduct through the ESE lightning arrester and the high voltage spike will get grounded safely.

The key purpose of using the ESE lightning arrester is to become the fast conductive point of discharge for the lightning bolt & ground current safely. Hence the current discharge gets distributed evenly throughout the ground and thus protects the structure. And when the lightning strikes, the device allows the lightning leader from the cloud and grounds it safely through the installed grounding system. Through the grounding system, the positive charge rises to the tip of the lightning rod. The lightning arrester is placed at a dominant height, making it a favourable point for the lightning bolt to strike. Their effectiveness is decided based on their position, morphology, materials used, and physical reaction that is performed due to the electrostatic field during the lightning. The conventional lightning arrester consists of Franklin rods. Types of lightning arrester – conventional For more info on lightning arresters, feel free to read this blog on “ Why do we need Lightning Arresters?” Now, we will discuss the clear difference between the conventional lightning arrester and ESE lightning arrester by understanding their working. The lightning arrestor provides the low impedance path when the traveling wave of lightning reaches a certain level and gets grounded without affecting the structure. The lightning arrester defends the power system by forwarding this high voltage surges to the ground. Hence to protect the structure and electrical systems, the lightning arresters are used. The wiring or the electrical systems of the facility may get damaged due to the voltage surge. And it directly hits on any facility or electrical service. Let’s start off by discussing the working principle of lightning arresters.Ī lightning bolt generates a voltage surge. In this article, we will discuss the difference between Conventional and ESE Lightning Arresters. There are different types of lightning arresters, they protect our structure & electrical systems from getting affected by lightning. But are we aware of the fact that we need to protect our structure and electrical system from it too? Yes, there is a device called a lightning arrester. Well, we all are aware of the lightning strike that occurs during the rainy season. Follow us on LinkedIn for regular updates on everything about Lightning Arresters!
