How to calculate number of steps & reactive power of the capacitor …
Thus the number of capacitors is identical to the number of steps: six capacitors controlled by six steps. However, compensation banks with unequal steps, for example 50 kvar and 25 kvar (see Figure 1), enable compensation in ''fine-stepping'' mode.Smaller units up to 150 kvar approximately have combinations of different-sized …

For the capacitors the fuse link rated current should be 1.6 time of the rated reactive current of the capacitor. I n =Q / (U n ×√3) where: U n – rated voltage of the mains, Q – rated power of the capacitor at rated mains voltage. Not only capacitors should be protected against short circuit, but the whole capacitor bank as well.
