Additional Notes

The objective of this project is to upgrade the outdated feeder protection relays in the 11kV switchgear at the Hajar 66kV Substation. The current relays (P122) are no longer available on the market, so the plan is to replace them and retain the existing ones as spares for use in other substations. This approach ensures the continued reliability and availability of the protection system across the network. This upgrade aims to enhance the safety, reliability, and performance of our electrical system. The scope of work includes the removal of obsolete protection relays, installation of new state-of-the-art protection relays, and ensuring seamless integration with the existing infrastructure. ,الهدف من هذا المشروع هو تحديث أجهزة الحماية للمغذيات القديمة في لوحات المفاتيح ذات الجهد 11 كيلوفولت بمحطة حجر لنقل الكهرباء ذات الجهد 66 كيلوفولت. الأجهزة الحالية (P122) لم تعد متوفرة في السوق، لذا يتم التخطيط لاستبدالها والاحتفاظ بالأجهزة الحالية كقطع غيار لاستخدامها في محطات نقل كهرباء أخرى. يضمن هذا النهج استمرار موثوقية وتوافر نظام الحماية عبر الشبكة. يهدف هذا التحديث إلى تعزيز السلامة والموثوقية وأداء النظام الكهربائي. يشمل نطاق العمل إزالة أجهزة الحماية القديمة، تركيب أجهزة حماية حديثة ومتطورة، وضمان التكامل السلس مع البنية التحتية الحالية ,
