When noise equipment is connected to distribution board
These are examples using Japanese power line and distribution board.
If PLC 1 and PLC 2 can not communicate (influence PLC link) due to the influence of noise
equipment connected to distribution board B, installing (inserting) a noise filter in the sub breaker to
which the noise equipment is connected will often cause noise to decrease, and you can
communicate. (Noise equipment examples: fan motor, inverter, etc.)
In addition, when there are two main trunks (main breakers) in the distribution board, if PLC 2
connected to one with more noises can not communicate with PLC 1 in distribution board A,
change the connection beyond the main trunk with less noise. There are many times that noise will
be reduced and communication becomes possible.
