    Hi,
    If power factor correction capacitors are only available in blocks which are integer multiples of 10 kVAr, how close to the optimum value could the power factor be corrected in practice?

    Thanks

    That depends on the application.

    Motor inverters driving induction motors as a purely resistive load (FOC, for example) is more effective to reduce apparent power than a capacitor bank.

    it's all relative to the size of your load. Industrial units often have multiple banks of caps that are switched in and out in response to line conditions. With steady state loads they can hold very close to unity.
