Understanding Harmonics in EV Infrastructure
High current harmonics can lead to system failures and increased stress, and Distribution Network Operators (DNOs) may refuse to install chargers with high harmonic values. IEC standards and local regulations ensure the safe operation of power supply networks. Non-compliance can lead to penalties and the inability to install the charger. Circontrol, part of the Circutor Group, has over 25 years of experience in harmonic filtering. Their DC chargers, tested thoroughly, have excellent Total Harmonic Distortion values, always below 5%, and under 2% in the best cases.
