Main Indicators of Steady-state Power Quality

Steady State Main Indicators of Power Quality :

1, Power Supply Voltage Bias: Bias of Power Supply Voltage to Nominal Voltage.

2. Frequency bias: the difference between the practical value and the nominal value of the grid frequency.

3, three-phase imbalance: percentage of square mean root value of negative sequence weight and positive sequence weight of voltage or current.

4. Harmonics: Stop Fourier series synthesis for periodic sexual flow, and obtain a weight with a frequency greater than an integer multiple of 1 for the fundamental frequency.

5, voltage flicker: visual perception formed by unstable illumination of light.

6, voltage sag (voltage sag).

7, voltage swell (voltage swell).

8, voltage short infix.
