Hi
Please help me how to trasmit sine wave (1khz to 1Mhz ) on power line (24 volt). Its very urgnet for me from lastone month struglling.

 

how signals are pass through a power line

 

How? They are high frequency (>50/60hz) signals or data pulses 'superimposed' thru a small value mica or ceramic capacitor to the hot (110/220v) side of a step down transformer... which powers the lot.

You can learn alot by (sorry folks) 'Googling' Carrier-Current Transmission or avoid the NSA/CIA logging and 'use www.scroogle.org instead

See www.x10.com for all type of Carrier-current plans, projects and devices

Hope that helps!

 

if u need help in powerline communication send me email at <snip> with subject powerline, so tht it will be easier for me to notice...

i hardly visit 'allaboutcircuits' so i can miss your post in this page, it will be faster if u can send me email...

thank you

 

You need to be careful. The power company uses power line carriers and would not look kindly on people interfering with their signal on their own lines.

 

Another old thread.
