Handheld Power Quality Analyzer Suppliers and Manufacturers

Product description Electrical equipments in modern industrial, commercial and residential users are more sensitive to power quality, and have a higher requirement of quality of power supply. Currently, harmonics,electromagnetic interference, power factor reduction have been tied to the three hazard of the power system. When it is interfered or contaminated, grid power quality can t reach the national standards, so it has to be targeted on the grid power quality improvement. To understand the actual situation of power quality, you must have the appropriate equipment to test and analysis the actual situation. Counter the domestic condition, our company developed the professional power quality analysis instrument, which is suitable for the country. 3 phase handheld power quality analyzer Technical index 1.
