Abstract

يتألف خط نقل القدرة من ثلاثة نواقل ثلاثية الطور تتوضع في المستوي z=d فوق سطح الأرض. أجريت الدراسة على مجموعة من النواقل الثلاثة المتوازية ذات تباعد أفقي متساو. يتوضع الناقل المركزي الأول في المستوي y=0 بينما يتوضع الناقلين الثاني والثالث في المستويين y=±3m على الترتيب. تم تحديد مركبات الحقل الكهرطيسي في النقاط القريبة من خط النقل عالي الجهد الذي يرتفع عن سطح الأرض بمقدار 15m بالطريقة التحليلية. وبعد إيجاد منحنيات توزع شدة الحقل الكهرطيسي بتابعية البعد عن الخط المركزي y، لاحظنا أن شدة الحقل الكهربائي لها قيمة عظمى عند الموضع y=±9m، وحقل التحريض المغناطيسي من مرتبة الميكروتسلا. The power line consists of three wires, three-phase in the plane z=d over the earth surface. This study was carried out on the equally spaced horizontally conductor configuration. The central conductor 1 lies in the plane y=0 while conductors 2 and 3 in the planes y=±3 m, respectively. The components of electromagnetic field at all points near high- voltage transmission line is determined in analytical method. This study shows that the electric field strength has a maximum value at position y= ±9m, but the values of the magnetic induction field is of the order micro -tesla.
