A surge arrester intercepts electrical surges and sends them to ground before they damage connected devices. The terms surge arrester, surge protector, and lightning arrester are interchangeable. Lightning arresters prevent surges from outside the power grid, while surge protectors prevent those from inside. Industrial lightning arresters and surge arresters are the same and are almost always destroyed by waves. Surge arresters work by melting the line going to the protected device and pushing the voltage out through a grounding system, which can be dangerous if the grounding system is faulty.
A surge arrester is a device that intercepts electrical surges and sends the surge to ground before it can damage a connected device. These arresters are also known as surge protectors or lightning arresters, but there are some very minor differences between these devices. In most cases, when a surge arrester catches a surge, it fuses to prevent transmission. This will stop the wave, but it will also destroy the device. If the arrester is not installed correctly, this melting can cause more problems than the initial spike.
The differences between a surge arrester, surge protector and lightning arrester are very minimal. In many cases, these differences are more of a trend than an actual technological difference. In fact, these terms can be used interchangeably and still be correct.
The main differences between a lightning arrester and a surge protector are time and location. In the past, there were only lightning rods, as lightning was the only place where large current surges came from. Now, a lightning arrester typically prevents surges from outside the power grid, and a surge protector prevents those from inside.
Surge protectors also protect against grid surges, but they do it in a different way. They protect the systems by connecting to the wall, so they always have direct connections to the electricity grid. A device can be placed on any line that carries electricity. There are devices that plug into standard electrical wire, coaxial wire, and even speaker wire. Also, a surge protector is a long-term device, while a surge protector is a form of one-time protection.
From an industrial point of view, there are only two different types of protection. A surge protector prevents overloads on power lines only. These devices work similar to the home version; they are connected to the wall and to a protected machine, but will operate at much higher voltages. These devices will not necessarily be damaged by power surges.
Industrial lightning arresters and surge arresters are one and the same. They connect to any energy transfer line, whether it’s connected to a wall or between two machines. These are almost always destroyed by waves, regardless of location. Many machines have a surge protector that protects the machine from the wall and a surge protector that protects internal systems.
Surge arresters work by melting the line going to the protected device. This prevents voltage from traveling into the device and instead pushes it out through a grounding system. This is both the greatest strength and greatest danger of a surge protector. If the earthing system is installed correctly, the arrester will work properly. If the grounding system is faulty, the voltage has nowhere to go and can travel up the line or even start a fire.
