Transformers, like any other assets, produce their best output when they are in peak operating condition. To keep a transformer in optimum form, it is essential that regular condition monitoring is conducted. By doing this, potential problems are identified early, meaning less unplanned downtime, less maintenance required and longer periods without any maintenance needed.

What is important, though, is to identify all the parameters that can give a complete view of the transformer’s health, and insight into what remedial actions, if any, must be taken to ensure continued reliability.

Technical Bulletin 78 - the first in a series of transformer monitoring articles – features an in-depth discussion about the range of different condition monitoring techniques available for assessing transformer health.

Technical Bulletin 78 is only available in the digital version. You can download it for free here.
