A Ferrite Core Noise Filter (FCN) is a popular noise filtering device. They can be used to help reduce unwanted interference from outside sources, as well as to provide better isolation of cables and other devices. They are also commonly used in telecommunication and networking environments. It's a good idea to purchase a Ferrite Core Noise Filter if you're in an environment where noise and interference are a problem.
The first part of the technology was originally developed for standard data lines. The basic principle is to create a field that is a magnetically confined space with an air gap between the two. The magnetic field is what makes the signal go through, but it's also what provides the insulation from noise and interference. In order to prevent air gaps, the field has to be perfectly large so it fills the gap completely.
This is possible only when certain frequencies are present. An example of this is a ring of fire. A very large air gap, or inflow, will cause a point of light to fall through the ring. However, if the air gap is not large enough, there is no ring of fire.
The problem with having air gaps around a large source of electricity is that they have an effect on different frequencies differently. Most significantly, low frequency sound is hindered by air gaps while higher frequency sounds are unaffected. Noise from equipment is particularly difficult to block.
The reason why an air gap creates more energy loss than does a true magnetic field is because energy is stored in a magnetic field, which is basically a wave form. So, the energy loss from a wide gap in a space filled with air causes an additional energy loss that has nothing to do with the air and is not necessarily bad.
Another example of an environment that might need a Ferrite Core NoiseFilter is the power grid needs to transmit and receive electricity. Because of the distance between many power grids, the potential for transmission losses to cause low level noise becomes significant. This is especially true when the distance is from a large population center such as a city.
The amount of energy that is lost due to transmission noise can be significant, especially in a medium of this size. Not only does this have an effect on the cost of operating a grid, but it also limits the amount of electricity that can be produced. This can cause serious economic problems for a country.
Finally, when it comes to weather changes, heat increases the amount of heat that can escape from insulation. Since a Ferrite Core Noise Filter is designed to increase insulation, it is also a useful tool for helping reduce some of the thermal losses. Since so much heat is lost through the atmosphere, it's important to protect against this loss.
