Shielded Underground Cable Estimator1
1) These cable parameters are conceptual estimates and should not be used in production.
2) Positive sequence parameters use basic assumptions and simplified equations.
The cable manufacturer or vendor would provide these values based on installation specifics.
3) Zero sequence parameters use basic assumptions and simplified equations, likely with large error.
Do Not use these in production for system protection settings!
The cable manufacturer or vendor might provide good estimates based on installation specifics.
Field measurements based on fault data are really required to accurately calculate zero sequence parameters.
