Live front vs Dead front transformer

The main difference between a Dead Front Transformer and a Live Front Transformer lies in their high-voltage bushing design:

Dead Front Transformer: In a dead front transformer, the high-voltage bushing is separate and consists of a bushing well and a load break bushing insert. Both the bushing well and the load break bushing insert are insulated. High voltage cables are connected to the transformer using a deadbreak elbow connector. As a result, there are no exposed electrical components in the high-voltage section when the transformer is energized. This design minimizes the risk of accidental contact or electric shock.

Live Front Transformer: In a live front transformer, the high-voltage bushing is typically a one-piece spade type made of materials such as porcelain or epoxy. At the end of the bushing, there are usually 2-4 holes. High voltage cables are connected to these holes using a mechanical lug or a crim plug. Unlike the dead front transformer, the high-voltage bushing in a live front transformer is completely exposed. In cases where the bushing has moisture, oil, or dust, there is a possibility of generating an arc, which can pose a safety hazard.

These differences in high-voltage bushing design between dead front and live front transformers highlight the contrasting approaches to safety and insulation. Dead front transformers provide an additional layer of protection by separating the high-voltage bushing and using insulated components, reducing the risk of accidental contact or electrical shock. Live front transformers, on the other hand, have an exposed high-voltage bushing, making them potentially more susceptible to issues like arcing when exposed to moisture, oil, or dust.
