According to the following rules; Ecodial Advance Calculation proposes the type of regulation (fixed or automatic) of capacitor banks:
- If the power to be corrected (Q upstream + Q downstream) is greater than 15% of the apparent power of the upstream sources (sum of the apparent powers of upstream transformers used simultaneously), then Ecodial imposes power factor correction with an automatic capacitor bank.
- If not, a fixed capacitor bank can be used.
This principle is followed to avoid over voltages in the installation, when the installed power of the capacitor bank is high with respect to the consumption of the installation, then an automatic capacitor bank adjusts the number of capacitor steps connected according to the level of the loads on the installation.
