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 harm of harmonics to power capacitors mainly includes the following aspects 1. Overcurrent and Overload -Harmonics can cause distortion of voltage and current at the capacitor terminals, especially at specific harmonic frequencies, where capacitors resonate with inductive components in the system, resulting in significant amplification of harmonic currents. Excessive harmonic current causes th...
