Single Core High Voltage Power Cables
Single Core High Voltage Power Cables
(OP)
Could any one please tell me the relationship between positive sequence and zero sequence resistance / reactance for single core HV power cables.
I am looking for this information in connection with distance protection setting calculations for the 33kV Cable distribution feeders.
I tried some cable manufacturers' websites such as Okonite but to no avail. It would be helpful if I can obtain typical values for different size cables.
Thanks in anticipation.

You should be able to get data for particular cables by contacting the manufacturer.

Thanks for the response. I was told by a colleague that the zero sequence impedance would be equal to the positive sequence one. Is he right?

It would not be valid to use the ratio for this example on other cables or spacings.
