The relationship between capacitors and harmonics is very close, especially in power systems. The use of capacitors can affect the generation and propagation of harmonics, and are also easily affected by harmonics, leading to reduced performance or damage. Harmonic amplification In the power system, capacitors have a lower impedance to harmonics, so harmonic currents tend to flow through th...
Power quality refers to the characteristics of electrical power, including voltage, frequency, and waveform, that affect the operation of electrical devices. Typical products for power quality improvement include: Uninterruptible Power Supply (UPS): UPS systems provide backup power during outages and voltage sags, ensuring a continuous and stable power supply to critical loads. Voltage Regulators:...
The peak and effective value of harmonics When discussing the peak of harmonic currents, it's essential to first understand the fundamentals of harmonics. The effective value (RMS value) of a harmonic describes the average power of the harmonic component over one period, reflecting the equivalent extent to which the harmonic causes heating effects in the system. However, the peak of a harmonic (th...
