Transformer Asset Management
Power transformers are expensive and critical equipment in power systems and play a significant role in the transmission and distribution of electricity. Transformer asset managers’ focus is to achieve the required
levels of safety and reliability from their fleet of transformers at minimum cost. Knowledge of condition is therefore essential for efficient transformer asset management decisions. Without this information only the most basic activities are possible; such as time-based maintenance, replacement before end of life, or repair after failure.

The analysis of dielectric fluid in a transformer provides valuable information to assess changes in the internal condition of the transformer. These dielectric fluid tests are essential for the condition assessment, for the predictive maintenance and for preventing unexpected outages.
