|---|---|---|
| none | directly buried | This analytic method is according to IEC 60287-2-1 with objects buried directly in homogenous and thermally stable soil. Cables can be laid inside ducts. |
| dry | drying-out of soil | This analytic method is an extension to the directly buried method with object buried directly in thermally unstable soil. Backfills cannot be added but cables can be laid inside ducts. Buried systems with partial drying-out of the soil are limited to a single circuit according to IEC 60287-1-1. Consider sufficient spacing between the systems to limit mutual heating |
| back | with backfill | This analytic method is an extension to the directly buried method. Up to five non-empty rectangular or round backfill areas can be defined. Objects may also be installed outside of the backfills and cables can be laid inside ducts. |
| fem | finite element method | This numeric method uses finite element to calculate the external thermal resistance of the ambient outside of cables and ducts. All losses are still calculated according to IEC standard. Finite Element can result in significant deviations to IEC method |
| sub | installation subsea | This analytic method is in principle identical to the IEC Standard method. The preview is changed to represent objects buried in seabed underwater. The distinct subsea module offers more calculation methods in addition the IEC 60287 to allow for partially or non-buried cables but has other limitations in installation. |
