Harmonic Filters Can Mitigate Overloads And Overheating Of Power Infrastructure Caused By Load Harmonic Currents.

When nonlinear loads are present in a system, such as frequency converters, uninterruptible power supplies (UPS), or switching power supplies, these devices generate harmonic currents.

When electrical harmonic filter is deployed in a power distribution system, it plays a role in diverting or reducing harmonic currents injected into the load side or neutral line. During project implementation, harmonic filtration can be installed at the distribution cabinet or transformer inlet to reduce the content of high-order harmonics, thereby reducing the additional losses and heat deposition caused by harmonic components.

During the system thermal design phase, the overload risk caused by load harmonic currents must be considered. The deployment of harmonic filtering equipment helps to keep the temperature rise of busbars, transformers and cables within a controllable range. In data centers, power facilities, and large industrial sites, the "hidden" thermal effects of harmonics can lead to premature equipment degradation or sudden shutdowns.
