POWER QUALITY

[attachment=16593]

Overview: In a general sense, power quality is, quality power supply. However, because people look at problems from different perspectives, so far, the technical meaning of power quality, there are still different understanding, it can not give an accurate and uniform definition.

Over the years, the concept of power quality and reliability of electricity supply is almost identical. How to describe the interaction of both supply and power and influence, and gives the definition of appropriate technology is still the people continue to explore the issue. No matter what kind of power quality are given the definition of power quality of the content should include the following aspects of the content, a general consensus has been made to solve power quality test equipment, using power quality analyzer.

Voltage Quality: Given the actual voltage and the deviation between the ideal voltage to reflect the distribution of electricity power sector to the user is qualified. Voltage quality usually includes a voltage bias, voltage and frequency deviation, voltage unbalance, electromagnetic transient phenomena, voltage fluctuation and flicker, short duration voltage variation, voltage harmonics, voltage inter-harmonics, voltage gap, under voltage, over voltage.
