According to most definitions, a Lightning Arrester is a Device Used on Power Systems above 1000V to Protect other Equipment from Lightning and Switching Surges
Introduction: Digitalization has become a ubiquitous force, revolutionizing numerous industries and transforming the way businesses operate. In the realm of industrial electrical equipment, the advent of digital technologies has brought about significant changes, enabling increased efficiency, enhanced monitoring and control, improved maintenance, and the emergence of intelligent systems. This essay delves into the profound impact of digitalization on industrial electrical equipment, exploring its benefits, challenges, and future prospects.
Researchers at the Pacific Northwest National Laboratory recently developed a cylindrical powerhouse to transform low-frequency wave energy into a high-power electric output.
Every lightning protection system must undergo an acceptance test following installation.
Data and information technology systems are used in many different applications. Almost every electronic system used to process information is considered extremely important. Ever increasing volumes of data are being stored and must be accessible at all times at very short notice. It has become even more important to protect these systems too against dangerous surges. In order to prevent failure or even destruction of these systems, they must be integrated into the lightning and surge protection concept.
Very large surge voltages are caused mainly by lightning strikes on or close to energy systems.
Correct use of equipotential bonding systems prevents dangerous touch voltages between system components.
The lightning protection equipotential bonding represents internal lightning protection in the building. When lightning strikes, a voltage drop occurs at the earthing resistor, producing dangerous voltage differences between the metal building components and the power and data cables, which need to be prevented. The equipotential bonding connects together all metal installations (gas and water pipes, etc.), electrical systems (power and data cables), the lightning protection system and the earthing system, either directly or via lightning current arresters (SPD type 1 or type 1+2). Surge protection devices (SPDs) can guarantee a voltage limitation according to the insulation coordination.
The standards specify that each system must include an earthing system.
IsCon conductor an insulated, high-voltage-resistant arrestor is used in the field of external lightning protection to reduce or avoid the separation distance according to IEC 62305-3 (VDE 0185-305-3).
