What is the function of lightning arrester? The difference between lightning arrester and lightning arrester

February 02,2023

One of the worst natural disasters is the lightning tragedy. Every year throughout the world, lightning-related calamities claim countless lives and destroy vast amounts of property. As electronic and microelectronic integrated equipment is used increasingly frequently, lightning overvoltage and lightning electromagnetic pulse are damaging an increasing number of systems and pieces of equipment. Therefore, it is crucial to find a quick solution for the lightning catastrophe protection of structures and electronic information systems. The installation of surge protection devices (SPD) to suppress surge and instantaneous overvoltage on the line and discharge overcurrent on the line has become one of the key components of contemporary lightning protection technology due to the increasingly strict requirements of relevant equipment for lightning protection. What makes a lightning arrester different from a lightning arrester will now be discussed.

1、 What is the function of lightning arrester

An electronic device called a lightning arrester offers safety protection for different electronic instruments, tools, and communication connections. The surge protector can conduct shunt in a very short amount of time to prevent surge damage to other circuit equipment when a spike current or voltage is unexpectedly generated in an electrical circuit or communication line due to external interference.

The surge protector is suitable for use in power supply systems with AC 50/60HZ and rated voltages of 220V/380V. It can protect against both direct and indirect lightning impacts as well as other transient overvoltage surges. It can be used for surge protection requirements in residential dwelling, secondary industries, and industrial domains.

2、 Difference between lightning arrester and lightning arrester

1. While the lightning arrester often only has low-voltage goods, it has multiple voltage levels that range from 0.38KV low voltage to 500KV ultra-high voltage.

2. To stop lightning waves from directly invading a system, the majority of lightning arresters are installed on the primary system, whereas the majority are installed on the secondary system. The employment of lightning arresters as supplemental measures occurs when the direct invasion of lightning waves has been eliminated or when the lightning arresters are unable to totally eliminate the lightning waves.

3. Electrical equipment can be protected by a lightning arrester, however these devices are typically used to safeguard instruments or meters.

4.The lightning arrester should have enough external insulation performance because it is connected to the electrical primary system, and most of them will have a reasonably large appearance size whereas most of them will have a relatively modest appearance since they are connected to low voltage.
