What harm can power harmonics from variable-frequency power supplies cause?

Thread Content

During normal operation, variable-frequency power supplies generate electrical harmonics. Those who are familiar with electricity know that such harmonics can cause certain damage to electrical devices in the surrounding environment. So what are these hazards? The technicians from Zhonggang Yangsheng will explain to you the various harms caused by the electrical harmonics generated by variable-frequency power supplies. 1. The harmonics generated reduce the efficiency of power generation, transformation, and consumption equipment. 2. It can interfere with communication systems, disrupt the proper transmission of signals, and even damage communication equipment. 　3. It causes series resonance and parallel resonance, amplifies harmonics, and results in dangerous overvoltages or overcurrents. 4. Accelerates the insulation aging of electrical equipment, making it easier for breakdowns to occur and thus shortening their service life ； 5. It increases the additional losses in power transmission, supply, and consumption equipment, causing the equipment to overheat and reducing its efficiency and economic viability. The above are some of the hazards that electrical harmonics generated by variable-frequency power supplies can cause to the surrounding environment. Of course, we can take certain protective measures to reduce or isolate the impact of these electrical harmonics on the surrounding area. The potential hazards to surrounding electrical devices may not be limited to just these points; if you know more, feel free to add it.
