The Transformer Maintenance and Testing Training Course offered by Oxford Training Centre provides a comprehensive and technically grounded understanding of how electrical transformers are maintained, tested, and monitored to ensure reliable and safe power system operation. Transformers are critical assets within electrical networks, and their performance directly influences system stability, efficiency, and continuity. This course is designed to equip professionals with structured knowledge and practical insight aligned with the expectations of Power System and Maintenance Training Courses, without promotional framing.
Transformers are subject to thermal, electrical, mechanical, and environmental stresses that can degrade insulation, winding integrity, and overall operational performance. This course focuses on transformer maintenance and testing as a systematic discipline, enabling participants to understand degradation mechanisms and maintenance requirements across the transformer lifecycle. Emphasis is placed on applying electrical transformer servicing training principles to both routine and condition-based maintenance activities.
Participants will explore power transformer preventive maintenance strategies that reduce the likelihood of failures and extend service life. The course examines industry-recognised transformer testing techniques and procedures, including diagnostic, acceptance, and condition assessment tests used to evaluate transformer health. These practices support informed maintenance planning and risk reduction across power and distribution networks.
The programme also addresses transformer inspection and troubleshooting, enabling participants to identify early warning signs of faults and performance deterioration. Attention is given to the maintenance of distribution and power transformers, recognising the operational differences between high-voltage power transformers and lower-voltage distribution units. Through structured analysis, participants will understand how inspection data, test results, and operating conditions inform maintenance decisions.
In addition, the course introduces transformer condition monitoring methods, supporting predictive maintenance approaches. Topics such as transformer safety and operational maintenance are integrated throughout, ensuring that maintenance activities align with safety requirements and operational constraints. By combining theoretical principles with applied maintenance practices, the course supports accurate transformer performance testing and develops practical industrial transformer maintenance skills relevant to modern power systems.
