That's the one I have to find out because the voltage pulse must not triggered the over voltage relay or over the cable specification. That's why I asked about dc pulse voltage injected to a ac power cable (without shutting down the line) because all of the theory that I could find is in dc...
my supervisor told me that there are 2 capacitive coupling sensor installed in ther overhead transmission line. So all I need is to add a pulse into it
about that, I don't know the cable yet because, he said I need to prove that the pulse can successfully transferred to the cable using the...
Here is another question. My supervisor ask me to build a line distance measurement in ac power cable (without shutting down the line). So i have reading for couple weeks. So I came up with using a pulse to measure the line through a contactless capacitive coupling device. So the question is...
No without disconnect the ac power... Like superimpose the pulse to the ac voltage...
I see the TDR is not a dc pulse. Because I looked into this website
https://www.epanorama.net/circuits/tdr.html
They use dc voltageas an input and i think the output is dc as well ( i don't see any...
Hi guys,
I want to ask a silly question but i don't get it yet. So for example I have a 10 kV ac voltage cable. And suddenly I applied a dc voltage pulse signal (like TDR). Is the signal will disrupt the ac voltage?
