A 240 kVA synchronous motor of rated apparent power consumes 95 kW of active power of the power grid. And it is possible to adjust it so that by working with this same active power, it compensates the power factor by providing reactive power (i.e., appearing with a capacitive component). How can you get this? What is the maximum reactive power that it can provide?
