Lightning strikes are one of the most formidable natural phenomena, posing serious risks to life, property, and infrastructure. A single lightning bolt can carry over a hundred million volts of electricity, wreaking havoc on unprotected electrical systems and structures. To safeguard your property and ensure the longevity of your electrical systems, installing a lightning arrester is a critical step.
At Just HardRich Global Resources Limited, Nigeria’s choicest Electrical Power and Control Engineering Company, we provide cutting-edge solutions to protect your assets from the destructive impact of lightning. In this post, we’ll delve into the workings of lightning arresters, their key features, and their importance in today’s power-driven world.
What Is a Lightning Arrester?
A lightning arrester is a specialized device installed along power lines, typically near transformers or electrical panels, designed to protect electrical systems from high-voltage surges caused by lightning strikes. Its primary function is to divert the dangerous surge of electricity safely into the ground, preventing it from damaging electrical components, appliances, or the building’s infrastructure.
Unlike lightning rods, which merely redirect lightning strikes to the ground, lightning arresters actively prevent voltage spikes from entering the electrical system. They are especially important in areas prone to thunderstorms or with sensitive electrical equipment that cannot tolerate sudden voltage changes.
For instance, consider a manufacturing plant in Nigeria operating advanced machinery. A lightning strike could damage these high-value machines, resulting in costly downtime. Installing a lightning arrester ensures these machines remain protected, saving the business from potential losses.
Types of Lightning Arresters
There are multiple types of lightning arresters, each tailored for specific applications. At Just HardRich Global Resources Limited, we provide customized solutions depending on your needs:
- Station Class Arresters:
Designed for high-voltage systems, these arresters are used in substations and other critical installations. They can dissipate large amounts of current and protect essential infrastructure like transformers and circuit breakers. - Intermediate Arresters:
These are used in medium-voltage systems and are suitable for commercial buildings and industrial setups. They offer robust protection against moderate surges. - Distribution Arresters:
Ideal for low-voltage systems, these arresters are used in residential areas to protect homes and smaller businesses from lightning surges. - Secondary Arresters:
These compact devices are installed within homes or offices to protect appliances and other low-power equipment.
Each type of arrester has specific applications, and our team at Just HardRich Global Resources Limited ensures the right device is installed for maximum protection.
How Does a Lightning Arrester Work?
A lightning arrester operates as a safety valve for your electrical system. When lightning strikes a power line, the electrical surge attempts to flow through the system. The arrester, which has two main terminals – a high-voltage terminal and a ground terminal – intercepts the surge.
Here’s how it works in more detail:
- Normal Conditions:
Under standard operating conditions, the lightning arrester remains inactive. Its internal insulation prevents any flow of current, allowing your electrical system to function normally. - Voltage Surge:
When a lightning strike occurs, the surge exceeds the arrester’s breakdown voltage threshold. At this point, the arrester’s insulation temporarily breaks down, allowing the excess current to flow directly into the ground terminal. - Post-Surge Recovery:
After safely diverting the surge, the arrester resets itself and returns to its non-conductive state. This ensures uninterrupted power supply to your home or business.
This process happens in a fraction of a second, protecting your electrical system from the destructive effects of the voltage spike.
Key Features of Lightning Arresters
To ensure maximum reliability and efficiency, a good lightning arrester should exhibit the following features:
- Quick Response Time:
A quality arrester, like those installed by Just HardRich Global Resources Limited, reacts instantly to voltage surges, preventing any delay that could damage your system. - High Durability:
Lightning arresters must withstand repeated surges without degrading in performance. Advanced materials like metal-oxide varistors (MOVs) are often used for this purpose. - Optimal Breakdown Voltage:
The arrester’s breakdown voltage should be slightly higher than the normal operating voltage of your system. This ensures it remains inactive during regular operations but springs into action during a surge. - Minimal Maintenance Requirements:
Modern arresters are designed to operate reliably with minimal upkeep, making them ideal for both residential and industrial settings.
Ideal Locations for Lightning Arresters
The efficiency of a lightning arrester largely depends on its placement. At Just HardRich Global Resources Limited, we recommend installing arresters at:
- Power Line Entry Points: Where electrical power enters your property.
- Near Transformers and Circuit Breakers: To protect critical infrastructure.
- Within Electrical Panels: To safeguard appliances and equipment.
Additionally, for high-risk areas, we suggest combining lightning arresters with surge diverters to provide comprehensive protection.
