power as a commodity, quality is the measure of weighing its value, different people have different understanding of power quality. So, what is power quality? How to weigh the main indicators of power quality?

Power quality, in a general sense, refers to high-quality power supply, including voltage quality, current quality, power quality and power quality.

to weigh the power quality of the label including: voltage bias, frequency bias, voltage three-phase imbalance, harmonic and inter harmonic, voltage and voltage flicker.

1. voltage bias: voltage bias refers to the supply voltage is not stable, there is a voltage rise or fall condition.

2. frequency bias: all power grids have the same request for power grid frequency and will not be changed by different power users. Each country has corresponding rules for frequency bias.

3. voltage three-phase imbalance: The value of the three-phase voltage exceeds the rule specification.

4. harmonics and inter-harmonics: A current or voltage whose frequency is an integer multiple of the fundamental wave is sinusoidal is called a harmonic. Non-integer multiples are collectively referred to as interharmonics.

5. voltage shake and flicker: regular changes in voltage in the power grid are called voltage shake, or random changes in multiples of 0.9-1.1. Flicker refers to the visual effect of voltage instability on bulb lighting.
