isolation circuits

give me the idea about isolation circuit
i mean any means to isolate the main circuit while interfacing with power line
normally for power line communication to transmit/receive data
isolation circuit may be any form of transformer
 

Re: isolation circuits

Isolation cicuits:

Galvanic - we have power transference between two circuits without the same reference point/ground.


Optocoupler
Transformer



There is Blocking of DC with a infinite series capacitor like in the previous options, but isn't Galvanic.
