Why Are Surge Arresters Installed At The Front End Of Each Major Piece Of Equipment In Areas Prone To Lightning Strikes?

In areas with frequent lightning activity, power systems and electronic equipment face significantly higher risks than in other areas. Lightning can induce high-amplitude transient voltage changes in the surrounding air and wiring, which can potentially travel along cables to the interior of equipment, causing impact stress on the insulation structure and control modules.

Scientific protection measures require guiding potential transient voltage energy to a safe path before lightning energy enters the system, thereby protecting critical downstream equipment. The design of 11kv lighting arrester price is to provide a low-impedance path during voltage surges, allowing the voltage pulse to be rapidly conducted from the line side to the grounding system, reducing the impact conducted to the equipment.

Installing 11kv lightning arreaster price at critical locations such as equipment inlets and outlets can alter the distribution of voltage transients, reducing the energy entering the internal structure through the equipment housing or circuitry. According to industry practice, devices located at main power supply inlets, important switchgear, and distribution panels are the most common installation points, consistent with the protection strategy's emphasis on "placement close to the protected object."
