Abstract

Metal pipelines are widely used for the transport of fluids and liquid and gaseous hydrocarbons. When these pipelines are installed near overhead power transmission lines, AC interference can occur between the high voltage power lines and pipelines. This interference can cause the appearance of induced voltages that present a risk of electric shock to the operator safety, direct effects on the pipeline, such as corrosion of the coating and steel. Evaluation of this coupling is necessary to ensure the safety of personnel and equipment connected to the pipeline. In this paper, an optimization method combining PSO with CSM is proposed to simulate the capacitive coupling between the HV power lines and aerial pipelines and analyze the different factors that affect the level of this coupling, the simulation results were compared with a previous study of specialty, the results are found in good agreement.DOI:http://dx.doi.org/10.11591/ijece.v4i4.6289

Abstract

Breakdown voltage characteristics of air gaps considered a random process we have investigated how to find relevant statistical different leading to breakdown or with standing during an impulse voltage test under the same condition for a plane high voltage electrode and a grounded electrode configuration.In the present paper methods of the modelling and prediction of the AC breakdown voltage  in point-plane air gaps are investigated. An analysis based on experiments design method has been developed with indicates that.Measurements to contain some relevant information test at early stages in reduced time frame investigation were done on a point-plane with barrier varying in position and size. The barrier used was mounted vertically between the electrodes.The use of methodology of experiments design is one of this methods and present an original idea in high voltage prediction problems several factors were considered,namely the distance between electrodes and different parameters of the barrier such us is dimension and his holes.The experimental results are compared with results from numerical simulations.We firstly present the principals of this model then we apply it to the study of barrier effect. A good agreement has been found between the computed and experimental results.
