Surge Arrestor 11-36kV(5kA-10kA)

SOHO Surge arrestors, also known as surge protectors or lightning arrestors, are essential components in electrical distribution systems used to protect against voltage surges and transient overvoltages. These devices safeguard the equipment, lines, and systems from damage caused by lightning strikes, switching transients, or other electrical disturbances. When it comes to distribution systems, surge arrestors serve an important role in maintaining the reliability and safety of the electrical network. Here are some key points about surge arrestors for distribution:

1. Surge Protection: Surge arrestors are designed to divert and dissipate voltage surges that can occur due to lightning strikes, switching operations, or other transient disturbances. They provide a low-impedance path for surges to travel to the ground, protecting the distribution system.

2. Types of Surge Arrestors: There are several types of surge arrestors used in distribution systems, including:

  • Lightning Arrestors: These protect against lightning-induced surges.

  • Metal Oxide Varistors (MOVs): Commonly used for voltage surge protection.

  • Gas Discharge Tubes (GDTs): Suitable for high-energy surges.

  • Silicon Avalanche Diodes (SADs): Used in low-voltage applications.

3. Voltage Rating: Surge arrestors are rated for specific voltage levels to match the distribution system's voltage. Common voltage ratings include 120V, 240V, 480V, and higher.

4. Coordination: In a distribution network, surge arrestors are often coordinated and installed at strategic points to ensure effective protection. They may be placed at substations, on distribution poles, or within distribution cabinets.

5. Voltage Limits: Surge arrestors have voltage protection levels and response times. The voltage protection level is the voltage level at which the surge arrestor starts to conduct, shunting the surge to ground. The response time is how quickly the surge arrestor responds to a surge.

6. Maintenance: Surge arrestors require periodic maintenance to ensure their continued effectiveness. This may involve visual inspections, testing, and replacement of faulty units.

7. Surge Counter: Some surge arrestors are equipped with surge counters to record and indicate the number of surges they've encountered. This information helps in monitoring their performance and determining when replacement is necessary.

8. Grounding: Proper grounding is crucial for surge arrestors to function effectively. They provide a low-resistance path to ground for the surges they divert.

9. Safety and Equipment Protection: Surge arrestors protect not only the distribution system but also the connected electrical equipment, preventing damage to sensitive devices and ensuring the safety of personnel.

10. Codes and Standards: Surge arrestors and their installation should comply with relevant electrical codes and standards to ensure safety and reliability.

Surge arrestors are an integral part of modern distribution systems, providing protection against voltage surges and helping to minimize costly downtime and equipment damage. Their selection, placement, and maintenance should be carefully considered to maintain the system's robustness and reliability.
