For a description of this LN, see IEC 61850-5 (LNs PROL, PSOL). PTTR shall be used for all thermal overload functions. Depending on the algorithm, the LN describes either a temperature or a current (thermal model). Temperature data objects are also provided by other LNs. Examples are the hot spot temperature in LN YPTR or the isolation gas temperature in LN
SIMG.
