Voltage stabilizers for production

In order to make the right choice of an industrial stabilizer, knowledge is needed not only about electrical engineering, but also about the model range of stabilization devices on the market in our country. You need to determine the required power, current fluctuations and most importantly, your financial capabilities.

First, you need to find out what voltage you have at the output of the network: single-phase or three-phase. A three-phase stabilizer is required for three-phase voltage, and a single-phase stabilizer for single-phase voltage, respectively. It is worth noting that the production of almost any type must be based on a three-phase network, since the energy consumption of machines and other equipment requires increased energy security. Almost all three-phase stabilizers include in their design three single-phase stabilizers connected to each other in a «star» - this is done for more or less equal loading of all voltage stabilization devices. The power difference in the phases should not be more than 60%, otherwise the stabilizer may overheat and be damaged.

Three-phase voltage stabilizer Shtil R100K-3. Power 100 kVA. Accuracy 4%. Weight: 325 kg.

To determine the required power of the voltage stabilizer, it is worth calculating the total power of all electrical devices that will be connected to a stable power source. When calculating the above indicator, take into account the devices that you will buy in the future. In this case, it is worth considering not the average power of the devices, but the peak, maximum. For the power of machines and other devices with high starting parameters, the starting power must be taken into account. It is necessary to take into account the power reserve, which is approximately 30%. If the voltage regulator is not working at maximum power, then its service life will increase significantly.

Some precision and medical devices require high output current accuracy. For measuring and medical devices, the amplitude of the current strength should be no more than 220 + -3%, more noticeable changes in the current strength can affect the quality of measurements and the operation of the device. For household appliances, fluctuations should not exceed 5%. If the requirements of the devices connected to the stabilizer are different, then the minimum current fluctuations should be taken as a basis.

Voltage stabilizers have some more parameters that are important for the operation of devices used in production. The ability of the stabilizer to withstand overload, the higher this ability, the higher the reliability and power reserve.For stable voltage sources with a high degree of overload, it is possible to ignore the starting power of devices with high starting power consumption. Protection against large network overloads and output short circuits can save the life of the stabilizer and equipment, and therefore your finances. If the output power is exceeded by 5-40%, the stabilizer turns off, thus saving the equipment connected to it from burning out. If a short circuit occurs at the stabilizer output, the emergency shutdown system will operate immediately. The ability to adjust the output voltage will help to use devices with non-standard requirements for the electrical network.

When you buy a voltage regulator, you need to make sure that it provides the output power declared by the manufacturer, otherwise you can pay the time and money spent to replace the damaged regulator. To prevent such problems, buy high-quality uninterruptible power supplies from well-known and reliable manufacturers.
