Efficiently install and fix industrial lightning arrestors by following these step-by-step guidelines. Lightning arrestors should be placed near the equipment they protect, connected between ground and phase in an AC system, and between ground and pole in a DC system.
Each phase of an AC system should have its own arrester. Metal oxide lightning arresters are recommended in the industry as they use a ceramic housing filled with metal oxide discs, providing effective surge protection. It is important to adhere to the IEC standard for lightning arresters and consider the minimum height of the building for lightning protection.
By following these guidelines, you can ensure the efficient installation of industrial lightning arrestors for optimal protection.
Understanding Lightning Arrestors
This article provides a step-by-step guide on efficiently installing industrial lightning arrestors. It covers the ideal placement, installation standards, and the use of metal oxide lightning arresters for effective surge protection.
What Is A Lightning Arrester?
In the field of industrial lightning protection, lightning arrestors play a crucial role in safeguarding equipment, structures, and personnel from potential damage caused by lightning strikes. A lightning arrester, also known as a surge arrester or lightning surge diverter, is a device designed to protect electrical systems from the harmful effects of power surges and transient voltages.
How Does A Lightning Arrester Work?
A lightning arrester works by providing a low-impedance path for the surge current to discharge, thereby diverting the excess electrical energy and preventing it from reaching the protected equipment or structure. It essentially acts as a buffer, absorbing the energy generated by lightning strikes and redirecting it safely to the ground.
Lightning arrestors are typically installed at points where the electrical infrastructure enters a building or facility, such as at the main electrical panel or distribution board. When a surge or transient voltage occurs, the lightning arrester detects the increase in voltage and quickly establishes a conductive path to ground, effectively dissipating the excess energy and protecting the connected equipment.
The Importance Of Lightning Arrestors In Industrial Settings
In industrial settings, where sensitive electronic equipment is often used, the installation of lightning arrestors is of utmost importance. These devices help prevent costly damages to machinery, downtime, and potential risks to personnel caused by lightning-induced power surges.
Lightning arrestors provide a reliable and cost-effective solution to mitigate the risks associated with lightning strikes and power surges. By diverting the excessive electrical energy away from the equipment, they ensure the smooth operation and longevity of electrical systems in industrial settings.
Overview Of The Iec Standard For Lightning Arrestors
The International Electrotechnical Commission (IEC) has established standards for the design, installation, and testing of lightning arrestors. These standards ensure that lightning arrestors adhere to strict guidelines and provide reliable protection against lightning-induced power surges.
The IEC standard specifies the requirements for lightning arrestors in terms of their performance, mechanical strength, electrical characteristics, and testing procedures. It also provides guidelines for proper installation and maintenance to ensure optimal performance and safety.
By adhering to the IEC standard, industrial facilities can ensure that their lightning arrestors are of high quality and effectively protect their equipment and assets from lightning strikes.
Assessing The Installation Requirements
When it comes to installing lightning arrestors in industrial buildings, determining the ideal placement is crucial. The location of your lightning arrestor can greatly impact its effectiveness in protecting the equipment it is installed for. To ensure the maximum safety and efficiency of your lightning arrestor installation, it is necessary to consider a few factors:
- Proximity to the equipment: The lightning arrestor should be placed near the equipment it is meant to protect. By positioning it as close as possible to the equipment, you minimize the distance for lightning surges to travel and increase the chances of successful diversion.
- Linking between ground and phase: In an AC arrangement, the lightning arrestor is generally linked between ground and phase, while in a DC system, it is connected between ground and pole. This connection ensures that any surges are directed towards the ground, bypassing the equipment.
- Separate arrestors for each phase: AC systems typically require a separate lightning arrestor for each phase. This allows for optimal protection of all phases and reduces the risk of surges affecting other equipment.
When installing lightning arrestors in industrial buildings, there are several factors that need to be taken into account to ensure a successful installation:
- Structural layout: The layout of the building should be considered to determine the most suitable locations for lightning arrestor installation. Areas with high equipment concentrations or areas that are more exposed to lightning strikes should be prioritized.
- Type of equipment: Different types of equipment have varying levels of sensitivity to lightning surges. It is important to consider the equipment’s vulnerability and select appropriate lightning arrestors accordingly.
- Distance from power lines: If the building is in close proximity to power lines, the risk of lightning strikes increases. In such cases, extra precautions should be taken and lightning arrestors should be installed accordingly to mitigate this risk.
- Compliance with regulations: Ensure that the installation of lightning arrestors adheres to the relevant industry regulations and standards. This will help guarantee the safety and compliance of the building.
The ideal location of a lightning arrester in relation to the equipment it protects depends on the type of system and the specific requirements of the equipment. Generally, the lightning arrestor should be installed as close as possible to the equipment, with the appropriate connections to ground and phase or ground and pole.
In an AC system, separate arrestors for each phase might be necessary to ensure comprehensive protection. By positioning the lightning arrestor near the equipment, it creates a direct path for lightning surges to be safely diverted to the ground, protecting the equipment from damage.
When it comes to lightning arrestors, there are different types preferred in the industry, each with its own advantages and applications. The most commonly used lightning arrestors in industrial settings are:
| Type | Description |
|---|---|
| Metal Oxide Lightning Arrester | Metal oxide lightning arresters are a newer type of arrester that use a ceramic housing filled with metal oxide discs. The metal oxide material has a highly nonlinear resistance that decreases with increasing voltage, providing effective surge protection. |
| Gapped Silicon-Carbide Arresters | Gapped silicon-carbide arresters utilize a series of gaps filled with silicon-carbide materials to provide surge protection. They are known for their durability and reliability in high-energy environments. |
| Gas Discharge Tubes | Gas Discharge Tubes, also known as spark gaps, utilize a short gap filled with gas. When a surge occurs, the gas ionizes, providing a low impedance path for the surge to travel, thus protecting the equipment. |
Choosing the appropriate lightning arrester type depends on the specific requirements of your industrial setting and the equipment in need of protection. Consulting with a qualified professional can help you determine the best lightning arrester solution for your particular needs.
