    Transformer Protection and Transformer Fault | Electrical4U· While for all small size distribution transformers, only high voltage fuses are used as main protective device. For all larger rated and important distribution transformers, over current protection along with restricted earth fault protection is applied. Differential protection should be provided in the transformers rated above 5 MVA.

    Substation Health Risks | EM Watch emit a low-frequency electromagnetic radiation (EMR) which creates an electromagnetic field (EMF). This EMF has two components, an electric field and a magnetic field. Don't worry too much about the electric field. It lacks power to penetrate the substation walls. But the magnetic field goes right through bricks, concrete, or a human body.
