Lightning arresters are important components for safeguarding electrical systems from the effects of lightning strikes. They can be installed in a wide variety of power systems, including extra-voltage AC arrangements and HVDC structures.
They are usually a cylindrical object, one to two feet long. They have a spark gap and series inductor to divert electricity from high-voltage lines to the ground, which protects your home’s wiring and electrical devices from damage.
How to Connect Lightning Arrester:
There are a few things you need to consider before connecting a lightning arrester, such as the voltage rating of your system and the frequency of your power line. You’ll also need to pick the rated nominal discharge current for the lightning arrester, and check for temporary overvoltage.
The rated nominal discharge current should be greater than your system’s peak (phase-to-ground) voltage rating and greater than the maximum frequency of the power line. Make sure that you use a quality lightning arrester from a manufacturer that provides high-quality products with proper characterization, testing, and maintenance.
How to Size a Lightning Arrester:
When sizing lightning arresters for your application, you should start with MCOV ratings expressed in phase-to-ground voltage, at the terminals. For metal oxide varistors, the rated nominal discharge current is also a good place to begin.
You can also use TOV ratings, which represent the phase-to-ground voltage at the end of the arrester’s life, as well as the MCOV rating. However, this can be quite tricky.
It’s recommended to consult a qualified electrician for assistance. They can help you find the best lightning arrester for your needs and install it safely without any issues.
How to Choose a Surge Suppressor:
A surge suppressor is a device that can help you prevent electric surges, transients, and voltage spikes caused by lightning, switching, or electrical faults. It can be installed inside or outside your home.
They can also be used in commercial settings and other buildings to prevent electrocution. They also provide a path for lightning to disperse, so that you can enjoy peace of mind in your home or office.
How to Install a Lightning Rod:
A lightning rod is a simple, inexpensive method for protecting your property from the negative impacts of lightning. They come in many different sizes and are designed to be easily mounted on the height of your building or transmission towers.
The main reason for the installation of a lightning rod is to provide a path for the lightning surge to get to ground. This will prevent your structure from getting blown up and damaging the wiring, as well as preventing electrical surges that can lead to fires and explosions.
How to Connect a Lightning Arrester:
The most basic lightning arrester is the spark gap. These are made of ZnO or SiC and are non-conductive under normal conditions, but become conductive when a high voltage is applied across them. These are the most common lightning arresters and are often called “spark gap insulators” or “silicon carbide insulators.” They are typically mounted near a critical circuit point, such as the generator, and activate when a bolt of lightning strikes to divert the voltage and current away from your equipment and into a safer path.
