The check involves measuring the input current of each capacitor battery. The check must be carried out using a true RMS
meter reading:
Check per phase current delivered by each capacitor and compare it to nominal values. In case of capacitance losses or
unbalance, the capacitors must be replaced.
Make sure the current through the capacitor does not exceed 1.3 x Ir. A higher value may indicate a strong presence of
harmonics, which will impact the lifetime of the capacitor.
The absence of current despite the capacitor being energized indicates a fault. This defect is conrmed by removing the
capacitors and checking the underside.
