AbstractThis paper presents the finite element electrothermal analysis done on an industry standard Kevlar armored subsea power cable to determine the cable overload and short circuit ampacities up to 256 times the continuous current rating. It is identified that the subsea cable could withstand 1.5 times and 256 times the rated current for a period of 17 min and 4.8 ms, respectively. The ampacity correction factors for operation in the water medium for a range of temperature and water flow velocities are also identified. The results presented in the form of equations shall serve as a guideline for determining the overload and short circuit protection settings of subsea power cables of similar construction.

Current Reduction

Electrical resistors for power lines are used worldwide as Neutral Earthing Resistors for short-circuit current reduction in power grids, and also as Filtering Resistors in combination with capacitors and inductances. The manufacturers of such resistors must certificate that they withstand the mechanical and thermal stresses imposed by the external loads, in accordance with IEC 62001 standard. Although this certification can be achieved by means of testing the resistor under working conditions, this process is both expensive and time-consuming. In this paper it is proposed a methodology for simulating the thermal and mechanical behavior of an electrical resistor, based on Multiphysics Finite Element Analysis. The methodology has been applied for the analysis of a filtering resistor for the Ethiopia-Kenia Power Systems Interconnection. Keywords: Earthing and Filtering Resistor, Multiphysics Finite Element Analysis, IEC 62001 short-circuit behavior.
