Introduction to Lightning Arrester

Lightning arresters are devices installed to shield power lines, homes, and structures from dangerous power surges. As the name suggests, they're primarily designed to safeguard against damage caused by lightning strikes. However, they can also protect the structure from various other sources.

Types of Lightning Arresters

 

 

Horn or ESE Lightning Arresters
Horn or Early Streamer Emission (ESE) lightning arresters are designed to provide advanced warning and protection against lightning strikes. These arresters have a pointed metallic rod that extends above a surrounding system of radial metallic plates. When an electrical field associated with an approaching lightning strike reaches a certain threshold, the ESE arrester emits a streamer, effectively capturing the lightning before it can strike the protected structure.


Valve or Spark Gap Lightning Arresters
Valve or spark gap lightning arresters are based on the principle of creating a low-resistance path for lightning currents. They consist of two or more metal electrodes with a small air gap between them. Under normal operating conditions, the air gap acts as an insulator. However, when a high voltage surge, such as a lightning strike, occurs, the spark gap breaks down and allows the surge to pass through and be safely conducted to the ground.


Carbon Electrode Lightning Arresters
Carbon electrode lightning arresters utilize carbon or graphite rods as the main conductive element. These arresters are effective in diverting lightning currents due to the high electrical conductivity of carbon. Carbon electrode arresters are commonly used in high-voltage applications and can withstand multiple lightning strikes without significant degradation.


Gas Tube Lightning Arresters
Gas tube lightning arresters use a small hermetically sealed gas-filled chamber to protect against lightning surges. Inside the chamber, there are two electrodes separated by a small gap. When a surge occurs, the gas breaks down and forms a low-resistance path, allowing the surge to be safely discharged. Gas tube arresters have a fast response time and are commonly used in telecommunication systems.


Hybrid Lightning Arresters
Hybrid lightning arresters combine multiple technologies to provide enhanced protection against lightning strikes. They typically incorporate elements of both valve and gas tube designs, resulting in improved surge handling capabilities. Hybrid arresters are often used in critical infrastructure, such as power substations and data centers, where high levels of protection are required.


Surge Protective Devices (SPDs)
Surge protective devices (SPDs), also known as transient voltage surge suppressors (TVSS), are a type of lightning arrester used to protect electrical systems from transient voltage surges caused by lightning strikes and other sources. SPDs work by limiting the voltage level of incoming surges and diverting excess energy safely to the ground. They are commonly installed at the main electrical service entrance to provide comprehensive protection to an entire building or facility.

Working Principle of Lightning Arresters

 

 

Lightning arresters help prevent lightning damage to the apparatus because of high voltages. The lightning arrester provides a low-impedance road all the way to the ground for the lightning’s current. It then restores to a normal operating condition. A lightning arrester can be compared to a relief valve on a water heater. It releases high pressure until it can work normally again. When the pressure returns to normal, then the safety valve is ready for the next move. When a high voltage exists on the line, the lightning arrester immediately forms a path to the ground, limiting and draining the excess voltage.

Installation Tips for Lightning Arrester

Select the Location
Surge arresters should be installed at strategic locations on the power distribution network where there is a high risk of overvoltage transients. This may include near transformers, circuit breakers, and other critical equipment.


Prepare the Mounting Surface
The surge arrester should be installed on a stable and secure mounting surface. This may include a concrete pad, a metal frame, or a pole.


Connect the Ground Lead
The ground lead of the surge arrester should be connected to the grounding system of the power distribution network. This provides a low-impedance path to the ground for the transient energy, diverting it away from the protected equipment.

Connect the End Fittings

The surge arrester should be connected to the power distribution network through its end fittings. The end fittings may include a connector, a terminal, or a bushing, depending on the specific application.

Verify the Connections

Once the surge arrester is installed, the connections should be carefully verified to ensure that they are tight and secure.

Test the Surge Arrester

The surge arrester should be tested to verify its electrical performance. This may include testing its response to simulated surge currents and verifying its voltage rating.

Ultimate FAQ Guide to Lightning Arresters

Q: What is the difference between a lightning arrester and a surge protector?

A: Surge arrester protects the installation from inside while lightning arrester protects the equipment from outside. Surge arrester protects the system from lightning, switching, electrical faults, and other transients voltage and surges while lightning arrester is mainly used for lightning strikes and associated surges.

Q: What is the difference between a lightning conductor and an arrester?

A: When the lightning surge occurs, it reaches the ground through this conductor. Whereas a lightning arrester is part of the power network and carries power under normal conditions. But under the lightning condition, it directs that surge to the ground and prevents further damage to the network/system.

Q: What is the main purpose of a lightning arrester?

A: A lightning arrester, surge arrester or line arrester is a device used on electrical power systems and telecommunications systems to protect the insulation and conductors of the system from the damaging effects of lightning. The typical Lightning Arrester has a high-voltage terminal and a ground terminal.

Q: Do I need lightning arrester on my house?

A: Most residential homes don't need lightning protection. However, if you have the following conditions then a lightning rod and lightning protection makes sense: You live in an area with a high frequency of lightning strikes. The home is tall.

Q: Where should lightning arresters placed?

A: Lightning arresters are generally located on both the high and low side of a substation transformer to protect it from strikes coming in either direction.

Q: What is another name for a lightning arrester?

A: A 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.

Q: What does a lightning arrestor look like?

A: As the name suggests, they're primarily designed to safeguard against damage caused by lightning strikes. However, they can also protect the structure from various other sources. Lightning arresters are cylindrical objects, one- to two feet long, consisting of a series inductor and a spark gap.

Q: Why do lightning arresters fail?

A: Moisture ingress is probably the leading single cause of arrester failures worldwide – both for porcelain-housed arresters and most likely for hollow core polymeric-housed arresters as well. Such ingress takes place either through the metal diaphragms that are part of the venting system or around rubber seals.

Q: How do I know if my lightning arrester is working?

A: The most common method is visual inspection: checking that the arrester has no visible external mechanical damage. However, an arrester with no visible external damage can sometimes suffer internal damage. As a result, it may not be able to protect against a surge or overvoltage.

Q: Do lightning arrestors go bad?

A: An arrestor fails when the flow does not shut off and the primary voltage keeps going to the ground until the arrestor blows. If the arrestor gets dirt and or moisture inside of it this causes it to conduct primary voltage to ground and fail.

Q: How does a lightning arrester work?

A: A lightning arrester does not prevent lightning from striking a home or business. It is typically installed between the power line and the home, substation, or circuit breakers. Lightning rods differ from arresters in that they are passive rods that absorb lightning strikes and send them through an attached cable to the ground. The electrical circuits still run the risk of being affected by the sudden surge in power when using a lightning rod only. A lightning arrester has a high voltage terminal and a ground terminal. The current spike naturally wants to flow to the electrical components. This is where the lightning arrester comes in. It diverts excess current into a predetermined location.

Q: What are the key features of a surge (lightning) arrester?

A: ● A properly working lightning arrester breaks down quickly when exposed to an abnormal voltage over the rated breakdown value. A “breakdown” refers to the function of the lightning arrester wherein the insulation inside breaks down momentarily so that the voltage surge can be directed to the ground.
● It should divert the current at the precise moment that the transient voltage reaches the rated breakdown threshold.
● The spark-over voltage must go beyond the usual power frequency occurring in the system for the device to work. It shouldn’t be electrically conductive under normal conditions.
● Lastly, the lightning arrester should channel the discharged electrical energy without losing its durability when these breakdowns happen.

Q: How safe is lightning arrester?

A: A lightning arrester can save your building by providing a low-resistance path for the lightning to follow, diverting the electrical charge away from the building and its occupants. Lightning arresters work by capturing the electrical discharge and then grounding it safely.

Q: Should I use surge arresters or lightning arresters?

A: In short, the decision to choose one among them varies on the kind of protection you need. The purpose of both of them is to protect your home. Because both these tools tend to protect your home, either of them should work effectively. In most situations, homeowners may choose either one as protection. However, one should consider certain aspects of what they are trying to protect. Rest assured, any one of the tools can provide the right kind of protection needed for the electrical appliances at home. When in doubt, homeowners can call a certified and experienced electrician who can provide them with the right solution. Because every home is different, the needs vary as well. The experts have specific recommendations tailored to the needs of every individual.

Q: Where a lightning arrester should be located

A: An arrester should be located close to the equipment that is supposed to be protected. Usually, they are connected between the phase and the ground in an AC system and the pole and the ground in a DC system. If you have an extra-high voltage AC system, then the lightning arrester is used to protect generators and transformers as well as bus bars, lines, and circuit breakers. In an HVDC system, the lightning arrester is used to protect buses and valves converter unit reactors, etc.

Q: How to maintain a Lightning Arrester?

A: ● Clean the outside of the arrester housing
● De-energize the line before handling the arrester
● Check the earth connection periodically
● Record the readings of the surge counter
● Securely fasten the line lead to the line conductor and arrester
● Securely fasten the ground lead to the arrester terminal and ground

Q: What is a metal oxide arrester?

A: Metal oxide surge arresters are commonly used in electrical networks and devices to protect them from high-voltage surges. The metal oxide semiconductor material in the arrester acts as a resistor, and it's designed to absorb energy from any surge of voltage or current that exceeds safe levels.

Q: How is a lightning arrester installed?

A: It is typically installed between the power line and the home, substation, or circuit breakers. Lightning rods differ from arresters in that they are passive rods that absorb lightning strikes and send them through an attached cable to the ground.

Q: How often should lightning arresters be inspected?

A: It is recommended that all Lightning Protection Systems be visually inspected at least once per year. In some areas where severe climatic change occurs, it might be advisable to instead visually inspect systems semi-annually, or following extreme changes in ambient temperatures.

Q: What happens if a lightning arrester fails to work?

A: If protection fails or is absent, lightning that strikes the electrical system introduces thousands of kilovolts that may damage the transmission lines, and can also cause severe damage to transformers and other electrical or electronic devices.
