1. How Does A Lightning Arrestor Work?

A lightning arrestor is a crucial component in protecting electrical systems from damage caused by high voltages during a lightning strike. It works by providing a low-impedance path to ground for the lightning’s current. This allows the surge of electrical energy from the lightning strike to safely dissipate into the ground, preventing it from damaging the connected devices and electrical infrastructure.

Explanation Of How Lightning Arrestors Prevent Damage From High Voltages.

During a thunderstorm, when lightning strikes or nearby electrical disturbances occur, a large amount of electrical energy is released. This surge of energy can travel through power lines, telecommunication cables, and other conductive pathways, posing a significant risk to connected devices and infrastructure.

A lightning arrestor acts as a safeguard by diverting this excessive electrical energy away from the protected equipment. It does so by using a spark gap or a combination of metal oxide varistors (MOVs) and gas discharge tubes (GDTs). These components provide a low-impedance path to ground, allowing the high voltage of the lightning to flow through them instead of reaching the sensitive electrical devices.

Importance Of A Low-impedance Path To Ground For Lightning’s Current.

A low-impedance path to ground is essential for effectively diverting the lightning current. The low impedance ensures that the electrical energy encounters minimal resistance as it travels towards the ground. This path should have a significantly lower resistance than the connected devices to ensure that the majority of the electrical energy bypasses them and safely dissipates.

By providing a low-impedance path to ground, the lightning arrestor prevents voltage buildup and limits potential electrical surge damage to the connected equipment. It also minimizes the risk of electrical fires and ensures the safety of personnel working with or near the electrical system.

Restoration To Normal Operating Condition.

Once the lightning surge has been diverted and dissipated into the ground, the lightning arrestor returns the electrical system to its normal operating condition. It does this by quickly restoring the flow of electricity, ensuring that the protected devices can resume their normal functionality without any lasting damage.

This rapid restoration to normal operating condition is crucial, especially in critical systems or environments where downtime and interruptions can lead to significant financial losses or safety hazards.
