13.11 - Power factor correction
The verification consists in measuring input current of each capacitor bank. Check shall be done 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.
Ensure that the current through the capacitor doesn’t exceed 1.3 x Ir. A higher value may indicate heavy presence of harmonics,
that will impact the lifetime of the capacitor.
Absence of current despite capacitor is energized is an indication that there is a defect. This defect is confirmed by removing the
capacitors and checking the underside.
