What made you select MRC Component’s MRC Rolls as a product to feature? Why is it important that MRC Rolls Suppress Harmful Interference Currents?
I selected MRC Rolls to feature because they provide a significant cost and implementation benefit for customers who need to suppress harmful interference currents and reduce radiated emissions.
Electric and magnetic fields, or electromagnetic fields (EMF), are linked together and form electromagnetic waves. Activities such as power generation produce EMFs and radiate emissions as a side effect of generation. However, very strong electric and magnetic fields endangers health and life, therefore it is necessary to limit the range of the EMFs and their associated radiated emissions.
At wind farms, for example, it is common for radiated interference and magnetic interference to influence other fields. For instance, nearby model-airplanes crash, or house cables (pipes) near wind farms might make strange sounds. Often, it is very difficult to measure such interferences correctly because it is a radiated emission emanating from a large area with no centralized chamber. Thus, shielded cables are used to reduce the amount of radiated emissions. In the case of old installations, it is very difficult to exchange unshielded cables with shielded cables, and it’s close to impossible in huge installations. Exchanging old cables with new ones is also a very expensive option. Furthermore, even with shielded cables, magnetic fields can still appear.
In order to maintain the strict emission targets, it is necessary to use either additional filters or inductive absorbers which work at radiated frequencies and help to reduce such emissions by absorption. Easy to install and to retrofit, MRC Rolls as well our adapted filter cores provide an easy and cost effective solution.
What are the key features and specifications of MRC Components MRC Rolls?
- MRC Rolls are a quick and convenient solution of absorbing harmful radiated interference from unshielded cables
- Easy to install and to retrofit, the MRC Rolls provide an easy and cost effective solution to shield radiated emissions
- Offerings cover power ranges from 7 to 800 kW
What are common markets/applications of MRC Rolls?
Because MRC Rolls suppress harmful interference currents, any market or application that needs to limit the range of EMFs and their associated radiated emissions can benefit from MRC Rolls. Some of these include:
- Wind Parks/Farms
- Solar Parks/Farms
- Solar installation on the roof or top of buildings
- DC Power Supply Systems
- Radio systems
