 20 Jul 2004 16:03 Data and high Voltage Separator |
|
|
|
Hi every body,
Did any you all know how to inject and separate a data from a high voltage line ? example if I want to send a data through electric 110 Vac or 240Vac line. How to inject the data in and how to separate the data at the end of the line ? If there is a literature about it is better.
Thanks

This is a very dangerous operation. You have to use components rated for mains use. Otherwise you will end up with a fire or damaging the electronics or its operator.
In general, you use series capacitors to the line for the data and clamp on ferrite on the mains in the direction the data is not to go.

I don't know what the "traditions" are but I would use a High-Freq transformer in series with a small capacitor to prevent the burning out of the transformer.
Capacitor must be calculated in such a way so that it is not resonant with the transformer at AC line frequiency,i.e. 60 or 50 Hz.
The AC line has a line impedance which must be matched with the transformed impedance of the output/input electronic device.
