When managing large electrical loads, especially those reaching up to 3kW, it is critical to consider the impact on the wider electrical system. Phase angle control methods, often employed by devices to regulate power, can inadvertently introduce unwanted harmonic currents into the power system. These harmonics are distortions in the electrical waveform that can lead to several detrimental effects, including:
- Electrical and radio interference: Harmonics can disrupt communication systems, leading to noise or interference in radio signals and other communication equipment.
- Overheating: Excessive harmonic currents generate additional heat in electrical components, reducing their efficiency and potentially leading to premature failure.
- Equipment damage: Devices such as inverters and other sensitive electrical equipment are particularly vulnerable to the stress caused by harmonics, which can degrade performance or cause permanent damage.
