“…The modes leading to failure of the CSEs are still under investigation. Generally, cable accessories, such as CSEs, are potential hot spots in cable circuits therefore temperature related effects are likely to be involved [13,14]. The effect of increased heating due to increased harmonic levels from power electronic converters has also been investigated [15].…”

This paper reports on a method combining the use of finite element simulations and external measurements to provide preliminary condition diagnosis of oil-filled cable sealing ends (CSEs) without requiring downtime. Good agreement has been obtained between the predictions from the electric field and thermal simulations and the measurements on a 132 kV oil-filled CSE. The electrostatic computation combined with electric field measurements can provide information regarding the electric field distribution inside the CSE and help in identifying potential issues with the CSE design, the materials or the cable termination process. The thermal computation combined with thermal imaging can reveal potential problems, such as high resistance connection to the busbar, and provide information regarding the cooling efficiency of the liquid dielectric. The method presented can provide the starting point for prioritizing maintenance operations on CSEs.

“…The highest conductor temperature in a cable system often occurs within a cable accessory rather than in a straight cable run. It is therefore important to study temperatures in cable accessories, both with full-size experiments and using computer models [2]. One of the dominant factors of cable termination fault in medium voltage circuit breaker compartment is due to excessive heating phenomenon.…”

The temperature distribution along the length of the termination of a single core cable as well as the maximum temperature location are calculated using an analytical method. Also, parameters affecting the maximum temperature along the length the medium voltage cable termination such as: the ambient temperature, the cable load current, insulation thermal conductivity, and termination dimensions (outer jacket length, length of the semi-conductor, length of the field regulator, thickness of the insulation, and thickness of the jacket) are discussed. The analytical method used is based on the heat flow produced by cable conductor and heat transfer by conduction, convection, and radiation.
