Notes
:
1) It should be noted that presence of harmonics produces over voltage & over current on capacitors.
Resonance may cause serious damage to installation if a significant level of total harmonic distortion level
exists for voltage or current. In such cases, series reactors must be considered.
2) Operating temperature class: in accordance with the reference standards, these temperatures are those
measured on the surface on the capacitor.
