  About us






Today, the situation on low voltage AC systems has become a serious concern. The quality of electrical power in commercial and industrial installations is undeniably decreasing. In addition to external disturbances, such as outages, sags and spikes due to switching and atmospheric conditions. There are inherent internal causes specific to each site and resulting from the combined use of linear and non-linear loads.
Untimely tripping of protection devices, harmonic overloads, high levels of voltage and current distortion, temperature rise in conductors and generators all contribute to reducing the quality and the reliability of a low voltage AC system. The current drawn from the ac mains has harmonic components, which causes to poor power factor, low efficiency, voltage and current distortion, interferences in some instruments and communication equipment by the EMI, over heated transformers and electromagnetic fields and increased losses in transmission and distribution systems.
The above disturbances are well understood related to the proliferation of loads consuming non-sinusoidal current, referred to as non-linear loads. This type of load is used for the conversion, variation and regulation of electrical power in commercial, industrial and residential installations.
