Protection transformers | Choosing the Right Transformer
There are two types of transformer configurations: Dry transformers Immersed or oil-filled transformers Dry transformers These transformers are composed of coils wrapped in an epoxy resin without intermediate liquid, which allows them to withstand thermal shocks well. The presence of epoxy resin prevents dielectric leakage and the risk of fire or explosion. The coating allows them to be resistant to external agents such as dust and humidity.  These...
