A Thunder Arrestor, properly called a Lightning Arrester, is a protective device used in electrical systems to protect equipment from high voltage surges caused by lightning.
What It Does
When lightning strikes a power line or nearby area, it creates a sudden surge of electricity.
The lightning arrester:
• Diverts the excess voltage safely to the ground
• Protects transformers, cables, meters, and appliances
• Prevents fire hazards and equipment damage
