Transformers
A transformer is a device that is used to either raise or lower voltages and currents in an electrical circuit. An electric transformer is used to switch voltage from one electric circuit to another. It consists of two coils, primary and secondary, that are connected to a magnetic field. These coils work as a conductor and the number of windings on these coils determines the ability of transformer.
Alta transformers ca be provided with the following options:
Case A) - Encapsulated with uniformly distributed resin thickness
Case B) - Production in shells or in insulated containers
Case C) - Metal containers
Case D) – Metal container with oil or inert gas proof seal
Case E) – In air / impregnated with resin and/or insulating paints
N.B: Cases A/B/C/E can be supplied in PCB versions
Case B) - Production in shells or in insulated containers
Case C) - Metal containers
Case D) – Metal container with oil or inert gas proof seal
Case E) – In air / impregnated with resin and/or insulating paints
N.B: Cases A/B/C/E can be supplied in PCB versions

Impulsive transformers
Produces with voltage insulation of 20kV max. and impulsive tensions
generate do not exceed 30 kV. Area of transfer. Unit of measurement in
Vµs.
This parameter defines the minimum area “tensions/time”.
Transferable form the primary to the secondary with minimum deformation
of impulse of entry.
