Understanding Lightning Arresters

Lightning arresters, also known as surge protectors, safeguard electrical equipment from voltage surges caused by lightning strikes. They divert excess energy to the ground, preventing damage to sensitive devices. Here’s what you need to know:


A typical lightning arrester consists of two main terminals:

  • High-Voltage Terminal: This terminal faces the power line and intercepts lightning surges.
  • Ground Terminal: The ground terminal provides a safe path for the diverted current to flow into the earth.

Smaller versions, known as surge arresters, are connected between each conductor in power and communication systems and the earth. These arresters allow high-voltage lightning currents to bypass connected equipment while protecting against normal power or signal currents.

Purpose and Function:

A lightning arrester acts as a barrier between electric wires and the ground. Its primary purpose is to safeguard the insulation and conductors of power transmission and telecommunication systems.

When lightning surges (or similar switching surges) travel along power lines toward the arrester, the arrester diverts the current through itself and directs it safely to the ground.

In telegraphy and telephony, lightning arresters are strategically placed where wires enter structures. This prevents damage to electronic instruments inside and ensures the safety of individuals nearby.

Working Principle:

When lightning strikes or a surge occurs, the arrester provides a low-resistance path for the excess energy.

By diverting the surge to the ground, the arrester prevents voltage spikes from damaging transmission lines, transformers, and other sensitive devices.

Without proper protection, lightning-induced voltage spikes can harm electrical appliances and even pose risks to human safety.


Lightning arresters are essential for:

  • Electric power transmission systems.
  • Telecommunication networks.
  • Protecting electric fences.
  • Safeguarding transmitters feeding mast radiators.
  • They can also form part of large electrical transformers.
Safety Measures:

High-voltage transformer fire barriers are necessary to withstand ballistics from small arms and projectiles from transformer bushings and lightning arresters.

Proper installation and maintenance are critical to ensure effective lightning protection.

Types of Grounding Methods

Lightning Arrester Grounding

Different grounding techniques include:

Grounding Rods: Buried rods dissipate energy into the earth.
  • Grounding rods, also known as grounding electrodes, are typically made of copper or galvanized steel.
  • They are buried deep in the ground near the structure or equipment that needs protection.
  • When a surge or fault occurs, the grounding rod provides a low-resistance path for electrical energy to flow into the earth.
  • The earth’s conductivity allows the energy to dissipate harmlessly.
  • Common applications include lightning protection systems and grounding for electrical substations.
Grounding Wires: Conductive wires connect the arrester to a grounding system.
  • Conductive wires connect surge protectors (such as lightning arresters) to a grounding system.
  • These wires ensure that any excess electrical energy is safely directed away from sensitive equipment.
  • Grounding wires are essential for preventing damage due to lightning strikes or power surges.
  • Proper installation involves connecting the wire to both the surge protector and a grounding electrode (such as a rod or plate).
Grounding Plates: Large metal plates spread energy over a larger area.
  • Large metal plates, often made of copper or aluminum, are installed in the ground.
  • These plates provide a broader surface area for energy dissipation.
  • When a surge occurs, the grounding plate spreads the energy over a larger region of soil.
  • The increased surface area enhances the effectiveness of grounding.
  • Grounding plates are commonly used in substations, communication towers, and industrial facilities.

Regular Maintenance and Inspection

Regular maintenance and inspection are crucial for ensuring the continued effectiveness of lightning arrester grounding systems:

  • Visual Inspections: Regularly check for physical damage, corrosion, and loose connections.
  • Testing: Conduct periodic resistance tests to ensure proper grounding.
  • Cleaning: Remove dirt and debris around grounding components.
