Harmonic Filters Can Indirectly Extend The Service Life Of Transformers.

low harmonic vfd By absorbing or reducing harmonic components in the system through circuit design, the power grid waveform is brought closer to an ideal sinusoidal state. This process of improving the power input waveform reduces the additional heat accumulation caused by harmonics. This filtering effect helps reduce the thermal load on the transformer, thereby delaying the aging of insulation materials and slowing down the performance degradation trend in long-term operation.

The deployment of power harmonic filter improves the stability of the power supply system, enabling the transformer to operate in a relatively stable electrical environment. If high-order harmonics generated by nonlinear loads such as fans and frequency converters are not managed, they can cause the transformer to experience irregular current carrying, leading to more frequent temperature rise cycles.
