Device for reducing the voltage at the base of the transformers are usually used in alternating

**current**. If there are surges, it is recommended to use stabilizing devices (ferroresonant stabilizers). The projected increase in voltage may compensate for an ordinary autotransformer. This device also will provide a reduction in the magnitude of the voltage within the specified range. At the heart of all these devices use different types of transformers.2

For low-power consumers in alternating

**current**you can use a damping resistor or capacitor. The value of the resistor (in ohms) can be calculated by the following formula: R = Uпад/I = (IP - U)/I. Capacitance (in microfarads) of the quenching capacitor can be calculated by the formula: C = 3200 I/, where R is the resistor value, Ohm; I is consumed by the device current, A; Uпад –**voltage**, which needs quenching resistor, In; IC –**voltage**network; U –**voltage**power supply devices, V.3

To reduce the supply voltage in DC

**current**, in most cases, are used sequentially included in the circuit the Zener diode, microbore stabilizer (ROLL) or switching Converter. Various types of these devices designed to reduce voltage to a certain value. The above electronic devices based on the properties of semiconductors. So their use requires a solid knowledge in electronic engineering.Note

Making the decision on choosing one of the above methods of reducing stress, it is necessary to follow the following algorithm:

to determine the amount by which required;

- choose one of the acceptable methods;

- to make calculations and make sure they are correct;

- perform all work with adherence to safety regulations;

- conduct the testing of circuits only when setting the rated fuses in electrical circuits.
