Distance protection relay - Reference temperature cable impedances
Distance protection relay - Reference temperature cable impedances
(OP)
Hello all
I need to parameterize a distance protection relay based on measurements of cable synchronous and zero sequence impedances on a 50 kV line.
However I am in doubt about the reference temperature to be used for the resistance values. We have measured them at 3°C, but I can´t find anything about requirements to which temperature the results are to be corrected. Are anything stated in the standards or manuals for distance protection relays and in case where ?
Best Regards
Hans-Henrik.

Try Anderson's Analysis of Faulted Power Systems.

Thank you very much for the answer. Are you able to make reference to an IEC, EN, etc. standard about the temperatures.
