A smart approach to electrical interference

REO UK has launched a range of power line filters to combat electromagnetic interference (EMI) and Radio Frequency Interference (RFI) on power lines. The CNW 161 and 163 filters are designed for building controls, renewable and factory automation applications. They are claimed to provide effective filtering in electrical power networks that use ripple control technology or data lines that use Power Line Communication (PLC).

The rise of Industry 4.0 has led not only a large number of electronic devices on lines, but also to a rise in the use of PLCs. This involves the transmission of data in electrical grids, often using existing lines to minimise costs. However, this further increases the likelihood of electrical interference.

REO’s power line filters tackle EMI and RFI by removing high-frequency electrical noise from the supply network, with a filtering range from 50kHz to 20MHz. Most electronic noise falls within this range and will be safely removed before it reaches the powered devices.
