What is Transformer?

Isolated transformer or isolation transformer; Used to isolate the load from the mains in case of a decrease or increase in the mains voltage. Transformers are produced as isolation transformer and auto transformer according to insulation type; single phase and three phase according to number of phases; mantel transformer and toroidal transformer according to core type. Isolated transformers are also called shore transformer, separation transformer or isolation transformer in the ship sector.

The earthing transformer is a special type isolated transformer that is used when the neutral earth voltage cannot be drawn to the desired level, although there is earthing in the workplaces. In establishments where earthing transformers are used, neutral-ground voltage is reduced below 1V.

If the voltage rises to a much higher level, it means that higher distribution voltages draw lower currents for the same power and therefore experience lower I2 * R losses along the mains-connected cable. These high AC transmission voltages and currents are then reduced to a much lower, safer and usable voltage level that can be used to power electrical equipment in our homes and businesses.

Transformers consist of 2 coils and these coils do not have electrical contact. They have a "core" structure that allows them to be interconnected by magnetic.

The fact that they do not make electrical contact with each other makes them isolated from electricity, thus reducing the possibility of collision and therefore it is called an isolated transformer.

ARTSAN Brand Transformers

The isolation transformer is usually given the input voltage from the primary winding, transforming it into a magnetic field. The secondary winding converts the alternating magnetic field to the required electrical power.

A standard Artsan transformer is produced by using 9,000 - 17,000 gauss, 0,20mm - 0,65 mm thick siliceous sheets as the core, and H class copper, aluminum and CCA wires in the windings according to the user's preference. Since B (t) / H (t) graph is taken into consideration during transformer design and calculations are made, transformers do not work in the saturation region. Flat and round wires are used in isolated transformer windings, as well as transformer options using foil winding technique.

After the winding and sheeting process is completed, transformers with CE certificate are removed from the vacuum boilers and starting the varnish process. After the varnishing process is finished, it is dried in the oven at high temperature. Thus, by preventing mechanical vibrations originating from the magnetic field, the heat generated in the transformer is further reduced and the loss is slightly reduced, thus extending the service life of the transformer.

Basically, an isolation transformer or a voltage transformer changes the voltage from the input winding by using the magnetic field and transmits it to the output. Transformer (Isolation Transformer) changes the mains voltage using the Faraday principle.
