Filter tips

Power line communication systems benefit from careful planning and prudent filtering. By Stefan Melly.

The application of power lines for transmission of signals and data is becoming more common but can be arduous to implement. Adding decoupling filters to power line communications (plc), especially when many 'networks' are operating on the same mains feed, promotes fault free operation and data security.

The plc filter is basically a mains filter with stringently specified safety and reliability features. An input filter to a house is, to the plc, what a firewall is to a computer network; it prevents the ingress of unwanted signals and interference – both of which can reduce the data throughput significantly.

Using a decoupling filter offers: protection for disturbances and external signals; data security; protection for the environment (or neighbour); optimised terminal impedance for maximum range, and perfect coupling between three phases.
