It hasn’t been that long since humans figured out how to create power grids that integrated multiple generators and consumers. Ever since AC won the battle of the currents, grid operators have had to ...

Let's look at key formulas that are the building blocks for the transfer of electricity: real and reactive power transfer formulas and their basics. The power triangle represents an essential building ...

We have a number of recognized transmission and distribution experts serving on our board of "Grid Masters." Several times each month we’ll post what we judge to be the toughest questions that also ...

Power factor correction uses parallel connected capacitors to oppose the effects of inductive elements and reduce the phase shift between the voltage and current. Power factor correction is a ...

If you’ve dealt with reactance, you surely know the two equations for computing inductive and capacitive reactance. But unless you’ve really dug into it, you may only know the formula the way a school ...

Understanding power factor (PF) is important because it gives us a clear understanding of the efficiency of an electrical system. Put simply, it’s the ratio of true power and apparent power, which ...
