Why do we need lightning arrestors on pylon that carry electricity?

Lightning arrestors are necessary on pylons that carry electricity to protect the equipment and infrastructure from damage caused by lightning strikes. When lightning strikes a pylon, it can cause a sudden surge of electricity that can damage or destroy the electrical components and potentially cause power outages. Lightning arrestors are designed to safely divert this excess electricity to the ground, protecting the equipment and preventing damage. This helps to ensure the reliability and safety of the electrical system.

Lightning arrestors are installed on pylons that carry electricity to protect the electrical system and equipment from damage caused by lightning strikes. Lightning is a sudden and powerful electrical discharge that can occur between clouds, between a cloud and the ground, or between the ground and a cloud. When lightning strikes a pylon, the massive surge of electrical current can travel through the electrical system, causing damage to transformers, insulators, and other equipment.

Lightning arrestors are designed to divert the lightning current away from the electrical system and into the ground. They are typically made of a metal oxide varistor (MOV), which is a non-linear resistor that has a high resistance at low voltages and a low resistance at high voltages. When lightning strikes the pylon, the MOV allows the lightning current to flow through it and into the ground, preventing it from damaging the electrical system.

Lightning arrestors are an important part of any electrical system, and they play a vital role in protecting the system from damage caused by lightning strikes.
