In accordance with IEC 60871-1, the inrush current should be limited to 100 times the rated current of the capacitor bank. When a capacitor bank is initially connected to a voltage source, the transient charging current will flow, attempting to equalize the system voltage and the capacitor voltage.
of a cycle, the moving contact closes the switch and allows current to flow without losses. Thus the apparatus is able to supply the capacito bank at the correct instant thereby minimizing transients caused by the switching o eration. imilarly, the capacitor bank is opened without causing any disturbance in the grid.
