Single phase safety and insulating transformers Safety transformer: It is an insulating transformer designed to supply circuit at a maximum of 50V (safety extra-low voltage). Insulating transformer: It is a transformer in which the primary and secondary windings are separated by a double or reinforced insulation, in order to limit, in the circuit supplied by the secondary winding, any risk due to accidental contacts with active parts or parts that can become active in case of an insulation fault. Impregnation: The transformers are completely impregnated with a inorganic resin. This...

High temperatures cause deterioration of the materials and shorten the "average life" of the transformer itself. For this reason the...
