Today, it is quite common to find private baths with a wood-burning stove and equipped with the use of age-old traditions, but with the addition of such a good of civilization as electric lighting, there is a need for calculating the transformer .
The fact is that the conditions in the bath are critical for electrical equipment operating from the voltage of a household network, a mandatory rule is to use a 12 V transformer and appropriate lighting devices. A wide selection of these devices is available in the electrical departments of household supermarkets. For those who want to make it on their own, we give the criteria for a preliminary calculation.
Parameters for the calculation
If there is a 220 V household voltage in a country house or cottage, it is necessary to install a network for connecting 12 V lighting devices to the adjacent or located on the site bath. For this you need:
- Determine the type of connection to the transformer - serial or parallel.
- Set the exact number of simultaneously switched on electrical appliances - 20% must be added to the total power according to the existing rules.
- Measure the thickness of the available copper wire - it will be used to make the primary and secondary winding of the transformer coil.
- Determine the type of transformer core.
In this case, we are talking about the conversion of an available used transformer to equipment capable of operating in a voltage reduction mode from 220 at the input to 12 V at the output, it is impossible to make all the necessary components yourself.
All that is needed at the preliminary stage of preparation is to accurately calculate the number of turns of copper wire of the primary and secondary winding of the transformer coil. The necessary physical formulas for these calculations are presented on the Otransformator information and cognitive site. The resource contains all the necessary background information with a detailed description in an accessible language understandable even for a non-professional, illustrated with clear diagrams and color photographs.
