A surge arrester is a crucial component in electrical systems, designed to protect electrical equipment from voltage spikes caused by lightning strikes, switching operations, or transient faults. The effectiveness of a surge arrester largely depends on the materials used in its construction, as they

Surge protection is crucial in safeguarding electrical and electronic devices from voltage surges or transient overvoltages that can cause damage or malfunction. Two commonly used devices for surge protection are surge diverters and surge arresters. In this article, we will explore the key differences between these two devices and their respective functions in protecting against electrical surges.

In our modern world, electricity powers nearly every aspect of our lives. From the lights in our homes to the machines in our factories, our dependence on electrical systems is undeniable. However, this reliance comes with its fair share of challenges, one of which is the occurrence of electrical su

At some point, all electrical equipment has an end-of-life-event (EOLE). Sometimes this event can be as benign as being removed and replaced with a newer device, but it can also be the by-product of a thunderous overload. In the case of distribution surge arresters, such a thunderous overload can trigger either a short or long-term outage.

Lightning accounts for about 60% of all transmission line trippings in China and is closely linked to season as well as region. Based on the physical processes, lightning overvoltages can fall into two broad categories: those caused by direct strike to the tower, shield wire or conductor; and those where lightning strikes the ground near lines, generating an induced overvoltage on conductors.

Increased penetration of Distributed Generation (DG) from solar and wind plants has created challenges for network operators when it comes to power quality issues such as voltage regulation, power factor and harmonics.
