Analysis of cable ampacities in cable systems containing harmonics

$15.00

The objective of this paper is to develop a method of calculation of cable ampacity in the presence of harmonics for a cable system. A simple general equation has been developed that can be used to calculate the “harmonic derating factor”–HDF, and “neutral harmonic derating factor”–NHDF of a cable system.
