Lightning Arrester

Lightning arresters in Mehsana, Kadi, Kalol, Deesa, Palanpur and Radhanpur North Gujarat, India are crucial components of lightning protection systems, especially given the country's susceptibility to lightning strikes due to its geography and climate. Lightning arresters, also known as surge arresters or lightning rods, are designed to safeguard structures, equipment, and personnel from the destructive effects of lightning strikes.
points of lightning arresters :
Types of Lightning Arresters : Various types of lightning arresters are used in India, including rod-type lightning rods, ESE (Early Streamer Emission) lightning arresters, and surge protection devices (SPDs). The choice of lightning arrester depends on factors such as the type of structure, location, and specific requirements.
Applications : Lightning arresters are employed in a wide range of applications across India, including residential buildings, commercial complexes, industrial facilities, telecommunication towers, power plants, and infrastructure projects like airports and railways.
Standards and Regulations : The design, installation, and maintenance of lightning protection systems, including lightning arresters, are governed by national and international standards. In India, the Bureau of Indian Standards (BIS) sets guidelines for lightning protection, including IS/IEC 62305 series, which covers risk assessment, design, installation, and maintenance of lightning protection systems.
Installation : Lightning arresters are typically installed at the highest points of structures to intercept lightning strikes. Proper installation involves ensuring adequate grounding and connection to the structure's electrical system to safely dissipate the lightning current.
Maintenance : Regular inspection and maintenance of lightning arresters are essential to ensure their effectiveness. This includes checking for signs of damage, corrosion, or degradation, as well as verifying proper grounding and connections.
Awareness and Education : Increasing awareness about the importance of lightning protection and the role of lightning arresters is essential for promoting safety and minimizing the risk of lightning-related damage and casualties.
lightning arresters are essential components of lightning protection systems, providing vital protection against the unpredictable and potentially devastating effects of lightning strikes. Proper selection, installation, and maintenance of lightning arresters are essential for ensuring the safety and resilience of electrical systems and structures.

    

Lightning Arrester

Components : Lightning Arrester
Spark Gap (older types): Air gap that breaks down under surge conditions. Non-linear Resistors/Varistors (modern types): Usually made from metal oxide (ZnO). Ground Terminal: For safely discharging the surge into the earth. Housing: Insulated body, often made of porcelain or polymer.
Works :
Normal Conditions: Arrester offers high resistance � negligible current flows.
Surge Occurs: Voltage exceeds a threshold ? arrester becomes conductive.
Surge Current Diverted: Energy is safely conducted to earth.
Post-Surge: Arrester returns to high resistance, resuming normal insulation.

Applications

• Transmission and distribution lines
  Substations
  Transformers and switchgear
  Telecommunication and control systems

Advantages

• Protects costly equipment from damage
  Fast operation � reacts in microseconds
  Long lifespan
  Low maintenance, especially in modern polymer types
