Why only 3-phase power system? why not 6 phase, 9 phase, 12 phase or some other phase? The number of phases in an electrical system is determined by a number of factors, including efficiency, cost, and ease of use. Three-phase systems are widely used because they offer a good balance between these factors. In a […]

The increasing use of modern power electronics (drives, uninterruptible power supplies, etc.) generates nonlinear currents and thus loads the network with harmonics. The capacitance of the capacitor forms a resonant circuit in conjunction with the power supply transformer. Experience shows that the self-resonant frequency of this circuit is usually in the range of 250 - […]
