WebNeher–McGrath method. In electrical engineering, Neher–McGrath is a method of estimating the steady-state temperature of electrical power cables for some commonly encountered configurations. By estimating the temperature of the cables, the safe long-term current-carrying capacity of the cables can be calculated. WebAccording to two different methods (IEC 60287, Neher-McGrath) the maximum current through a cable can be determined. 1. The Cable Ampacity of one pipe-type cable (without considering other nearby cables) is calculated. 2. The Cable Ampacity of the pipe-type cable and the parallel lines is calculated. A Cable Layout is used to consider the ...
