This summer, Gauteng has been hit with some truly vicious lightning storms. While the rain is a welcome relief, the lightning can wreak havoc on our electronic devices, including the often-overlooked gate motor.
A direct or nearby lightning strike can send a powerful surge of electricity through your gate motor’s system. This can fry the circuit board, damage the battery, and leave you with a very expensive and inconvenient problem. Not only will you be stuck manually opening and closing your gate, but you’ll also be facing costly gate motor repairs.
This article will guide you on how to protect your gate motor from lightning.
How to Protect Your Gate Motor from Lightning
Protecting your gate motor doesn’t have to be complicated. By taking a few preventative measures, you can significantly reduce the risk of lightning damage.
Here’s a step-by-step guide:
Step 1: Ensure Proper Earthing
Good earthing is the most critical step to protect your gate motor. Electricity always follows the path of least resistance to the ground.
An earthed motor provides a safe channel for the electrical surge to travel, diverting it away from the sensitive electronic components. An “earth spike,” which is a metal rod installed in the ground next to the motor, is a highly effective way to create a stable earth point.
This simple addition makes it much more likely that lightning will strike the rod instead of your motor.
Step 2: Install Surge Protection
Surge protectors are essential for safeguarding your gate motor’s electronics. These devices are connected to your motor’s power supply and are designed to “clamp” or block excessive voltages caused by lightning and power surges.
While a surge protector won’t stop a direct lightning strike, it will absorb most of the energy.
Step 3: Check for Built-in Protection
Many modern gate motors come with some form of built-in lightning protection. Manufacturers are well aware of the risks in regions like Gauteng and often include components like gas arresters and other surge-limiting elements directly on the circuit board.
When purchasing a new motor or getting your current one serviced, ask about its built-in protective features.
Step 4: Unplug During a Storm
If you know a major electrical storm is on the way, the simplest action is often the most effective.
Unplugging your gate motor from the mains power supply can prevent a surge from travelling through the wiring and damaging the unit. It might be a small inconvenience, but it could save you from significant repair costs.
Benefits of Protecting Your Gate Motor
Investing a little time and effort to protect your gate motor offers several advantages:
- Saves Money: You’ll avoid the high costs associated with gate motor repairs or full replacements.
- Ensures Convenience: Your gate will remain operational when you need it most, saving you from the hassle of opening it manually in bad weather.
- Improves Security: A functioning automated gate is a crucial part of your home’s security, and protecting it ensures it continues to keep you safe.
- Gives Peace of Mind: Knowing your gate motor is protected allows you to worry less every time a storm rolls in.
