Power transformers are one of the critical assets in any power system. Several diagnostic measures have proven to be successful in identifying underlying faulty conditions and thus to enhance dependability and reliability of the asset.
In this 4-day virtual workshop, we will share with you more about these power transformer diagnostic measures with up-to-date case studies and bring theory to life with demonstrations.
