Audited Supplier KGZW-130 Power Fault Detector Energy Power Quality Machine Power and Harmonics Analyser
Product Introduction
Power quality refers to the quality of AC electric energy supplied to the client through the public grid, which is generally referred to the good or bad situation of electric energy in the grid line. The power quality problem is mainly caused by the terminal load side. For example, the impact reactive load will cause the power grid voltage to fluctuate sharply, reducing the quality of power supply.
When the power quality of the power grid is interfered with or polluted, and cannot reach the relevant national standards, it is necessary to improve the power quality of the power grid in a targeted way. In order to understand the actual situation of power quality in the power grid, it is necessary to have the corresponding equipment to test and analyze it. In view of the actual situation in China, our company has developed a professional KGZW-130 flat panel power quality analyzer suitable for the national conditions in time.
