Page 3: Preface
Preface Power quality refers to the quality of the AC power supply via the utility grid to the user, which normally means the good or bad situation of the electric energy in transmission line. Power quality problems are mainly caused by the load side of the terminal. For example, impact reactive load will lead to serious fluctuates to power network voltage, and decrease the quality of power supply. -
Page 4: I Functions And Features
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. - Page 5 power quality caused by a variety of electrical equipment at different operating conditions. Record and store trend of electrical parameter, such as voltage, current, active power, reactive power, apparent power, frequency, and phase at a regular time. 9. It can do electrical equipment adjustment and dynamic monitoring during operation, and help users to solve the power adjustment and commission process problems.
