Transformers and Switchgear Technology for Power Systems

Course summary

Transformers and Switchgear technology has developed enormously in recent years and power distribution network engineers are encountering problems and choices today that are vastly different from those of just a few years ago.

This course is designed to give both experienced and newly qualified engineers a comprehensive overview of the role of transformers and an essential update on the latest switchgear technology to improve decision making for safe operation, maintenance and renewal.

The course covers a range of technical options and develops an understanding of switching phenomena essential for reliable system operation. The technology update will also give you an insight into future techniques and technology, by exploring new practices being developed to enhance system reliability.

This course can be enhanced by attending our one-day Oil Diagnostics and Analysis course.
