Explaining The Working Principle Of Lightning Arrestors
A lightning arrester, also known as a surge arrester, is a crucial component in circuit protection. Its main function is to safeguard electrical equipment against the destructive effects of lightning strikes and power surges. But how do lightning arrestors actually work? Let’s dive into the working principle of lightning arrestors.
Providing A Path For High-voltage Lightning Currents
When it comes to lightning strikes, the electrical currents involved are extremely high voltage and can cause significant damage to connected equipment. Lightning arrestors work by preventing the flow of normal power or signal currents to the ground, but instead provide a path through which the high-voltage lightning current can flow, bypassing the connected equipment.
The purpose of this mechanism is to limit the rise in voltage when a power line or communication line is struck by lightning or is in close proximity to a lightning strike. By redirecting the high-voltage lightning current away from the sensitive electrical equipment, lightning arrestors effectively protect them from damage.
The Role Of Lightning Arrestors In Protecting Electrical Equipment
Lightning arrestors play a crucial role in safeguarding electrical equipment against the destructive forces of lightning strikes and power surges. When a lightning strike occurs near the equipment, the arrester activates and provides a low-resistance path for the lightning current to flow safely to the ground, away from the connected equipment.
This rapid discharge of the lightning energy prevents it from traveling through the electrical circuit and causing damage. By diverting the high-voltage lightning current away from the equipment, lightning arrestors limit the potential rise in voltage, ensuring the safety and integrity of the electrical system.
In addition to protecting against lightning strikes, lightning arrestors also provide protection against over-voltages. When there is an excessive current in the system, the arrestor redirects the excess current away from the equipment, preventing potential damage or malfunction.
Lightning arrestors are essential components in circuit protection, offering effective defense against lightning strikes and power surges. By providing a path for high-voltage lightning currents and diverting them away from sensitive electrical equipment, lightning arrestors ensure the safety and integrity of the electrical system.
