These controllers allow power factor of the installation to be stabilized to the requested value by switching capacitor banks and inductive reactors through contactors. Power Factor Correction provide well-known benefits to electric power systems. These benefits include power factor correction, poor power factor penalty utility bill reductions, voltage support, release of system capacity, and reduced system losses. A high power factor signals maximum use of electrical power, while a low power factor leads to purchasing more power to obtain the same load kW, which you pay for in various ways on your utility bill. The controllers also visualize various AC parameters including a harmonic analysis of voltages and currents.
