Muscat: Oman Electricity Transmission Company has completed all construction and operational works for the project to install a Fault Current Limiter System on the 132 kV network in Muscat Governorate, at a total cost exceeding OMR4 million.
The fault current limiters are being installed to reduce fault current to a safe level without disconnecting the network, thereby protecting transformers, circuit breakers, cables, and other infrastructure from excessive thermal and mechanical stress.
They also help avoid costly equipment upgrades when current levels exceed design limits due to system expansion or the integration of new networks, ensuring the stability, safety, and reliability of the electricity grid while maintaining continuous power supply to the rest of the network.
This project is part of the company’s ongoing efforts to enhance the sustainability and resilience of the national electricity transmission network, aligning with its strategic goals to improve efficiency, reduce system failures, and ensure rapid response through the use of the latest smart technologies and global best practices in the field.
Eng. Masoud Salam Al Riyami, Head of Operations at Oman Electricity Transmission Company, explained that the project represents a significant strategic step in enhancing operational efficiency and power supply quality. It reflects the company’s commitment to investing in smart infrastructure that ensures better grid performance and supports national energy development objectives.
He noted that the company’s five-year strategic plans for assessing the grid’s condition and implementing future and current projects aim to build a smart transmission network that complies with the highest international standards, capable of keeping pace with growing demand and the energy sector’s transformation.
He emphasized the Company’s commitment to continuous development, cost-effective investments, and the deployment of high-standard systems to maintain the reliability and sustainability of the electricity transmission network, stating that the Fault Current Limiter System is a key step toward fulfilling this commitment.
It is worth mentioning that Oman Electricity Transmission Company, part of Nama Group, is responsible for transmitting and controlling electricity across Oman’s transmission network. Electricity is transmitted from production stations to load centers distributed across all governorates.
The transmission network operates at 132 kV and above, covering all governorates. The company also manages the interconnection lines between Oman and the GCC Grid at 220 kV.
