In a general sense, power quality refers to high-quality power supply. However, because people have different perspectives on the problem, so far, there are still different understandings of the technical meaning of power quality, and an accurate and unified definition cannot be given yet. To solve power quality testing equipment, use a power quality analyzer.
Because the shape of the Plastic Lobster Clasp Hook resembles a lobster, so it is called Plastic Lobster Claw Clasp.
The Plastic Lobster Clasp, also known as Plastic Lobster Claw Clasp, is made by POM plastic material, it has lots of colors in stock, more colors can be customized as Pantone color number as well. Check if you are interested in any of these colors below:

For a long time, the concept of power quality and power supply reliability have been almost equivalent. How to describe the interaction and impact of both power supply and power consumption, and give the corresponding technical definition is still a problem that people continue to explore. Regardless of the definition of power quality, the connotation of power quality should include the following aspects. A general consensus has been reached to solve power quality testing equipment and use a power quality analyzer ...
Voltage quality. Give the deviation between the actual voltage and the ideal voltage to reflect whether the power distributed by the power supply department to the user is qualified. Voltage quality usually includes voltage deviation, voltage frequency deviation, voltage imbalance, electromagnetic transient phenomena, voltage fluctuation and flicker, short-term voltage fluctuation, voltage harmonics, inter-voltage harmonics, voltage gap, undervoltage, overvoltage, etc.
At present, although there is consensus on the term and connotation of using power quality at home and abroad, there is no unified consensus on the exact definition of power quality. Several widely used definitions are as follows:
Definition 1: The concept of qualified power quality means that the power supply and the grounding system provided for sensitive equipment are suitable for the normal operation of the equipment. This definition comes from the technical definition of power quality given by the IEEE Standardization Coordination Committee.
Definition 2: Power quality refers to the physical characteristics of the power supply device under normal working conditions without interruption or interference with the user ’s use of power. This definition comes from the IEC (1000-2-2 / 4) standard. According to this definition, in addition to ensuring a sinusoidal waveform at rated voltage and rated power, modern power quality also includes frequency deviation, voltage deviation, voltage fluctuation and flicker, three-phase balance, waveform distortion, and all voltage transient phenomena such as Shock pulse, voltage drop, momentary interruption and power supply continuity. This definition includes the causes and consequences of power quality problems, as well as the reliability of power supply.
Definition 3: The definition of power quality refers to the characteristics of the voltage at a specified point in the power system. These characteristics can be evaluated according to predetermined benchmarks and technical parameters. This definition is given by the International Electrotechnical Commission (IEC). According to this definition, power quality can be regarded as voltage quality, and qualified power quality should be a sinusoidal waveform voltage of constant frequency and constant amplitude and continuous power supply.
