Definition And Purpose Of Lightning Arrestors

In the realm of circuit protection, lightning arrestors play a vital role in safeguarding insulation and components from potential damage caused by voltage surges. Also known as surge arrestors or surge protectors, lightning arrestors are devices designed to divert excess electrical energy to the ground, minimizing the risk of equipment breakdown or failure.

How Lightning Arrestors Protect Insulation And Components

Lightning strikes and switching in inductive circuits are common culprits behind voltage surges. When lightning strikes or an abrupt change occurs in an inductive circuit, it results in a sudden increase in voltage, known as a transient voltage. This surge can inflict substantial damage to insulation and components if left unprotected.

Lightning arrestors act as a preemptive defense mechanism by intercepting these voltage surges and shunting them to the ground, effectively protecting insulation and components from high levels of electrical stress. By providing a low-impedance path to ground, lightning arrestors redirect the excess electrical energy away from the sensitive circuitry, preventing potential breakdown and ensuring the smooth operation of electrical systems.

Sturdy lightning arrestors are equipped with two key components: a spark gap and a series inductor. The spark gap acts as a switch that instantly bridges the gap between the conductors when the voltage surge exceeds a certain threshold. This mechanism allows the excess electrical energy to be safely discharged to the ground, protecting the insulation and components.

On the other hand, the series inductor helps regulate the flow of the electrical current and prevent any unwanted disruptions. It acts as a buffer by impeding the flow of high-frequency surges while allowing low-frequency power signals to pass through. This balance ensures that the lightning arrestor effectively safeguards the circuit without interrupting the normal operation of the electrical system.

By employing lightning arrestors, electrical systems can effectively mitigate the risk of damage caused by lightning strikes and transient voltage surges. These devices provide a reliable and cost-efficient solution to protect insulation and components, ensuring the longevity and optimal performance of electronic systems and equipment.
