Sometimes it happens so that tension in network slightly below that which is necessary for normal functioning of devices. From this situation there is an exit. It is possible to increase tension very simply. For this purpose enough elementary knowledge of electrical equipment.
It is required to you
- Transformer
Instruction
1. To increase tension, will be necessary the simple textbook in physics and the lowering transformer (to what – it will become clear after some simple calculations provided below). So, primary winding of the transformer has to be on 220 volts, and its secondary winding has to be calculated on that tension on which just and it is necessary to increase tension in network.
2. Now take and analyze the following formulas: In = Rn? Un and P = U2? I2. By means of the first formula calculate current of a secondary winding of the transformer. After in calculation result P power becomes known, pick up the transformer which is the most suitable in parameters (power and output voltage) for the received results.
3. Further work with these formulas: Uvykh = Uvkh ± (Uvkh? Ktr) and Ktr = U1? U2. Thanks to these formulas becomes clear that for the correct result it is rather simply correct to phase (primary or secondary).
4. Install the received device in such place from which it will not disturb as in the course of work from the transformer quite unpleasant rumble proceeds. Therefore it is expedient to install the transformer somewhere in the basement or in the utility room.
