are suitable for use in a transformer. Research has been ongoing worldwide, and America appears to have had a breakthrough. In the US almost no mineral oil is being used anymore – at least not in the smaller transformers. They are using vegetable oils instead, such as palm oil or sunflower oil. The step towards using these oils in power transformers also seems near, but has not yet been fully realised. Developments come in rapid succession and experts are working hard, as clients in the branch increasingly need solutions. They want biodegradable oils, but these substances need to be treated with care, as vegetable oils have the disadvantage of spoiling quickly, when exposed to open air, for instance. So you have to be certain that your power transformer is completely sealed. What's more, cold air can quickly cause vegetable oils to become more viscous. And if that happens to your power transformer, you might just end up with a very expensive problem. So is it really worth it, spending so much time and money searching for alternative oils? Maarten van Woerkom from Royal SMIT Transformers B.V. thinks so. “There are many benefits. Vegetable oils are less scarce and easier to obtain. On top of that, they are more biodegradable and therefore less damaging to the environment. In the event of an accident with a power transformer using vegetable oil, there is less reason to panic. Furthermore, these oils burn less intensely.” 11 OVERARCHING BRANCHE ORGANIZATION
