Other Problems With Mineral Oil-Filled Transformers
Electrical transformers can hold hidden risks—mainly due to the type of materials used inside the transformers to cool and insulate them. The vast majority of today’s transformers are filled with liquid—a potentially dangerous one. The fluid traditionally used in transformers is petroleum-based mineral oil, a fluid with both a destructive environmental profile and the risk of fire should a transformer fail eventfully. Read about what can happen and how the effects of transformer failures can be mitigated.
