An increasing number of electrical devices are connected to the grid and cause various disturbances in the electrical grid. Some voltage spikes, some voltage drops, some frequency shifts, sometimes completely cut-off.

However, all of these devices, on which our vital dependence is gradually formed, require energy of high quality, that is, within the norms and which cannot tolerate even the slightest interruption.

Various devices can be used to prevent these disturbances in the network from reaching our sensitive devices. Choosing the most suitable for the purpose requires the evaluation of many factors. However, the only device that will eliminate all disturbances and prevent power cuts is uninterruptible power supplies. The components of a reliable power system are: Uninterruptible power supplies, rectifiers, inverters, transformers, filters.
