Mineral oil is widely used across a range of substation equipment and its performance is well understood and documented. Although standard mineral oil is used in a range of applications it would be advantageous to have alternative options for non-standard applications where mineral oil may not be the first choice. Although alternative oils have been available for a number of years it is necessary to build up a level of knowledge of their behaviour to gain confidence that they do perform as expected.
The use of mineral oil for insulation in transformers and switchgear is becoming more onerous over time, efforts need to be made to find reliable and sustainable alternatives.
