Utility power plant generators are usually designed for a power factor (PF) of .8 to .9. If demand-side PF is lower than the designed PF, the generator current will rise above the equipment's rated ...

Low power factor reduces an electrical system’s distribution capacity by increasing current flow. Therefore, having a low power factor is inefficient and expensive. But what is power factor and what ...

Two related phenomena, both called “power factor,” cause problems on electrical power lines. In each case, the ac current being drawn by the load is not exactly synchronized with the ac voltage on the ...
