Thunder Arrestor

Thunder Arrestor- What is it?

Imagine a tiny bodyguard for your electronics during a storm. That’s basically what a thunder arrester (also called a lightning arrester) is.

It’s a device designed to protect electrical systems from the powerful surges of electricity caused by lightning strikes. Instead of letting that lightning zap your equipment, the arrester diverts it safely to the ground, keeping your electronics safe.

According to Wikipedia, A thunder/lightning arrester (alternative spelling lightning arrestor) (also called lightning isolator) is a device, essentially an air gap between an electric wire and ground, used on electric power transmission and telecommunication systems to protect the insulation and conductors of the system from the damaging effects of lightning

Lightning arrestors, also known as lightning rods or surge protectors, are devices designed to safely divert the massive electrical energy from lightning strikes away from structures and equipment. They act as a shield, preventing damage and ensuring safety.

Types of Lightning Arrestors

  1. Metal Oxide (MO) Arrestors:
    • Utilize metal oxide varistors to absorb and dissipate lightning energy.
    • Commonly used in residential, commercial, and industrial settings.
    • Effective and reliable protection.
  2. Non-Gapped Line (NGLA) Arrestors:
    • Combine spark gaps with non-linear resistors.
    • Often found in substations and power distribution systems.
    • Provide robust protection against high-voltage surges.
  3. Externally-Gapped Line (EGLA) Arrestors:
    • Feature spark gaps in series with resistors.
    • Suitable for critical infrastructure and sensitive electronic equipment.
    • Ensure rapid discharge of lightning energy.

Thunder Arrestor Components

A thunder arrester, also known as a lightning arrester, is a fairly simple device with two key components:

  1. Diverter: This is the core element responsible for shunting away high voltage surges. In modern arresters, this is typically a Metal Oxide Varistor (MOV).

MOVs are special semiconductors that act like a variable resistor. Under normal voltage conditions, they have very high resistance, blocking current flow. However, when a sudden surge like a lightning strike occurs, the MOV’s resistance rapidly drops, allowing the surge current to safely pass through it.

  1. Housing: The thunder arrestor is encased in a weatherproof housing, usually made of porcelain or polymer. This protects the internal components from environmental factors and ensures safe operation.

Some arresters may also include additional components like:

  • Spark Gap: In older thunder arresters, a spark gap might be used instead of an MOV. This is a small air gap between two electrodes. During a surge, the air gap breaks down, allowing the current to flow. However, spark gaps are less precise than MOVs and can cause damage during operation.
  • Pressure Relief Valve: This safety feature releases excess pressure in case of an internal fault within the arrester, preventing it from exploding.

Installation and Grounding

Proper Placement of Lightning Arrestors

  • Install thunder arrestors at the highest points of structures.
  • Position them near electrical panels, communication systems, and sensitive equipment.
  • Ensure a clear path to ground.

The Critical Role of Grounding

  • Grounding is essential for effective lightning protection.
  • Create a low-resistance path to the earth.
  • Proper grounding minimizes potential damage.

Why Your Home Needs a Thunder Arrestor Solutions

Keeping your home safe from electrical dangers is crucial. One important tool you might not be aware of is a thunder arrester. Here are 5 reasons why installing one is a smart decision:

  1. Protection from Power Surges: Lightning strikes can cause unexpected surges of electricity that damage electronics. A lightning arrester acts like a shield, diverting these surges away from your appliances and safely channeling them to the ground. This helps prevent expensive repairs or replacements.
  2. Promotes Long-Term Equipment Health: By absorbing these surges, the arrester safeguards the electrical systems within your home. This reduces wear and tear, ensuring your appliances function properly for a longer lifespan.
  3. Reduces Risk of Electric Shock: Faulty currents or leakages can sometimes build up on the surface of electrical components. A properly grounded lightning arrester creates a safe path for these stray currents to flow directly to the earth. This significantly minimizes the risk of electric shock for you and your family.
  4. Eliminates Stray Voltages: Ideally, electrical lines should have zero voltage difference. However, external factors can introduce stray voltages. A lightning arrester helps eliminate these stray voltages, ensuring a safer and more stable electrical environment within your home.

How Lightning Arresters Work with Grounding Systems

Lightning arresters work in conjunction with grounding systems. Earthing, as it’s also called, involves creating a low-resistance pathway for excess electrical energy to flow directly into the ground. This rapid discharge protects your home from the damaging effects of lightning strikes.

To achieve this, a low impedance earthing cable is used. This special cable offers minimal resistance, allowing for a quick and safe release of electrical energy.

The Importance of Grounding Systems

A properly installed grounding system is essential for safeguarding your home and its occupants from electrical faults. These systems are relatively low maintenance, with most good quality kits lasting up to a decade.

By combining a lightning arrester with a grounding system, you create a comprehensive defense against the dangers of lightning strikes and electrical mishaps. This investment in safety provides peace of mind knowing your home and family are well-protected.
