Algorithm for Estimating Conductor Temperature in Three-Phase High-Voltage Cable Lines with Cross-Linked Polyethylene Insulation1

Resumo

Amathematical algorithm for calculating the real-time temperature of the conductors in three-phase high-voltage cable lines using data on the distributed temperature in screens and the current load in the conductors was developed. It was proposed that the heating of the cable conductors be calculated using equivalent thermal circuits constructed on the basis of the Van Wormer method.
