Stress control tubes (SCTs), made out of materials characterized by nonlinear electric properties, are widely adopted for the realization of cable terminations, in order to achieve a significant stress control. The influence played on the electric field distribution around the cable termination by SCTs parameters (e.g. length, thickness and position) has been studied only in the case of sinusoidal power frequency applied voltage, while no data can be found in the literature concerning applied standard impulse voltages. The purpose of this paper is to investigate on such interesting aspect by evaluating the potential distributions taking place under impulse voltages in cable terminations characterized by different arrangements of the SCT.

Abstract
Stress control tubes (SCTs), made out of materials characterized by nonlinear electric properties, are widely adopted for the realization of cable terminations, in order to achieve a significant stress control. The influence played on the electric field distribution around the cable termination by SCTs parameters (e.g. length, thickness and position) has been studied only in the case of sinusoidal power frequency applied voltage, while no data can be found in the literature concerning applied standard impulse voltages. The purpose of this paper is to investigate on such interesting aspect by evaluating the potential distributions taking place under impulse voltages in cable terminations characterized by different arrangements of the SCT.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
