چکیده
ABSTRACT: An intensive research work is carried out to determine the effect of humidity and contamination on cable termination and it’s aging. In this paper, the effect of atmospheric conditions on cable termination has been investigated by measurement of discharge inception voltage, discharge magnitude, dielectric loss and capacitance of each phase of cable. The three possible conditions i.e normal, wet and contaminated have been simulated in the laboratory. The deterioration is determined under simultaneous stress from applied voltage and contamination by measuring various parameters. It can be stated with some confidence that above mentioned factor under these conditions will help to know about the conditions of termination and aging of the cable. The cable was three phase Aluminum core XLPE cable and connected to switchgear through an epoxy resin bushing. Termination was made by heat shrinkable method.

متن کاملClassifying Faults Locations in Cable Terminations and Investigation of the Faults Reasons
Cable termination faults are problematic in electrical networks almost always. Technology has solved problems somewhat, but there are many annual reports about damaged cable terminations. For analyzing the problems, faults in two regional electricity companies are studied. At first step, damaged cable terminations are analyzed statistically and grouped according to their problems. Then, some of...
متن کاملEstimation of stresses in atmospheric ice during aeolian vibration of power transmission lines
Aeolian vibration in bare and iced cable was simulated using the theory of cable vibration. High frequency vibration creates stresses in the cable and consequently in the ice covering that cable, which may result in ice failure and eventually ice shedding. These stresses were estimated in this study. Displacement of the cable during vibration was determined; furthermore, instantaneous wind load...
متن کاملElectrical and Thermal Analysis of Single Conductor Power Cable Considering the Lead Sheath Effect Based on Finite Element Method
This paper investigates the effect of metallic sheaths on losses and temperature of medium voltage power cables. Two grounding methods of sheaths, including both ends bonding and single point bonding that causes different situations on cable ampacity, are considered. Electrical losses of cables that are main sources of heat are calculated in both conductor and metallic sheath of the cables. She...
