Special Issue Information
Dear Colleagues,
Power transformers are undeniably critical components within electrical power systems, playing a vital role in the efficient transmission and distribution of electrical energy by altering voltage and current levels. Their secure and reliable operation is vital to ensuring grid stability and a continuous power supply. However, transformers are susceptible to varied internal faults, such as inter-turn short circuits, winding failures, and core faults, and external faults, which can lead to severe consequences, including equipment damage, widespread power outages, and significant economic losses. Furthermore, abnormal operating conditions such as overloading, overvoltage, and insulation degradation pose persistent threats to their longevity and functional integrity.
This Special Issue, titled "Safe Operation and Protection of Power Transformers," will collate cutting-edge research and innovative engineering solutions dedicated to enhancing the safety, reliability, and intelligence of power transformers. Its scope encompasses both traditional protection philosophies and advanced diagnostic methodologies. We invite original contributions and review articles that explore novel approaches in protection schemes, such as improved differential protection algorithms capable of reliably distinguishing between internal faults and challenging transients, including inrush currents, and the application of artificial intelligence, including fuzzy logic and artificial neural networks, for fault diagnosis and decision-making.
Additionally, topics of interest include advanced condition monitoring techniques, such as dissolved gas analysis (DGA) and vibration analysis; predictive maintenance strategies leveraging real-time data; and smart monitoring systems for early anomaly detection and operational hazard mitigation.
Research on the safe integration of transformers into modern grid architectures, including challenges related to distributed generation and microgrids, is also highly relevant.
By bringing together research that bridges the gap between theoretical development and practical implementation, this Special Issue will contribute significantly to the body of knowledge aimed at minimizing transformer failures, optimizing maintenance, and ensuring the resilient operation of power systems. We believe that Energies, with its strong reputation in the field and commitment to high-quality, open-access research, is an ideal platform for disseminating these important findings.
