CJ-3D3YM multi-function power quality analyzer is a new generation of intelligent power meter. While measuring the basic power parameters of power lines in real time, the meter also provides power quality analysis, over-limit alarm, analog transmission, RS485 communication and other output functions. It is visual and clear display, beautiful interface, practical and simple operation.

It is mainly suitable for real-time measurement and analysis of line power quality in high and low voltage distribution systems, such as power plants, substations and distribution houses. It provides diagnostic basis for the operation of power grid and guides customers to advance power facilities.Preventive maintenance is carried out to improve the availability and reliability of electrical systems and equipment, reduce power loss and significantly improve economic benefits.

Function Feature

• Adopt 3.5 inch color dot matrix LCD display, Pixel density up to 180 PPI, The display content is exquisite and rich.
• The operation interface adopts desktop icon + visual list view mode, which is beautiful and generous, simple and practical to operate.
• Display interface can be freely switched to Chinese or English
• Measurements show all the parameters of 30, 31, Hz, kW, kvar, cos_, kWh in power lines.
• True RMS measurement, waveform distortion does not affect the accuracy of measurement
• The measurements show the 2-31 harmonic content, total harmonic distortion rate (THD), odd total harmonic distortion rate (TOHD), even total harmonic distortion rate (TEHD), total harmonic factor (THF) of three-phase voltage and current.
• It has the function of harmonic bar chart display, supports automatic adjustment of bar chart scale, supports displaying list data and spectrum chart.
• Measurable Display Voltage Peak Factor (CFU), Current K Factor (KFI)
• Measurable display voltage and current positive sequence, negative sequence, zero sequence, unbalance and other parameters
• Voltage and current waveform display, waveform amplitude scale can be automatically adjusted. The instrument adopts continuous, high-speed and real-time sampling mode, which can monitor and display the micro-dynamics of power network waveform (such as spike pulse, surge, power shaking, etc.) in real time.
• Provide phase angle, vector graph display function
• Three-phase voltage average value (Uavg), three-phase current average value (lavg), three-phase total current value (Isum) can be displayed.
• Recordable three-phase voltage, three-phase current, maximum active power (max) and minimum power (min)
• Maximum Active Power Demand (MD) and Current Active Power Demand (CD) can be recorded.
• Functions such as alarm of optional distribution quantity exceeding limit, input of switching quantity, analog quantity transmission, RS485 communication, etc.
