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 siginificant 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
250(2), 400(1) and 450(1) Vac.
