Voltage flicker monitoring device APVIEW500

（1） High precision real-time monitoring

1. Comprehensive coverage of power quality indicatorsAPView500 strictly follows the measurement methods for various power quality indicators specified in IEC61000-4-30 "Testing and Measurement Techniques - Power Quality Measurement Methods" for measurement. It can comprehensively monitor power quality parameters such as voltage deviation, frequency deviation, three-phase voltage imbalance, voltage fluctuations and flicker, harmonic distortion, voltage transients/dips/short interruptions, voltage and current transients, etc. For example, it can accurately measure voltage deviation, real-time grasp the degree of deviation between grid voltage and rated voltage, and provide accurate basis for factories to adjust voltage in a timely manner.

1. High sampling rate captures detailsThe device samples up to 1024 points per cycle and has measurement accuracy. This enables it to accurately capture the instantaneous distortion of voltage/current, even small changes in power quality cannot escape its "eyes". In terms of harmonic detection, it can cover 2-51 harmonics and ≤ 0.2%, providing reliable data support for factories to analyze the source and degree of harm caused by harmonic generation.

（2） Event recording and analysis

1. Accurate recording of transient eventsWhen transient accidents such as voltage surges, dips, and short interruptions occur in the power grid, APView500 will quickly trigger alarms and event recording functions. It records key information such as the time, duration, sag depth, and residual voltage of transient events in detail. For example, in a voltage sag event, the device can accurately record that the event occurred at 10:15:20 am, with a duration of 0.2 seconds and a sag depth of 70% of the rated voltage. This information is crucial for the factory to analyze the cause of the accident and evaluate its impact on production equipment.

2. Temporary source localization and analysisAPView500 utilizes the equivalent impedance algorithm and has the function of locating the temporary voltage source, which can accurately determine whether the temporary voltage source comes from the bus side or the line side. This feature helps factories quickly identify problem areas, take targeted solutions, shorten troubleshooting time, and improve production recovery efficiency. At the same time, the device will generate ITIC and SEMI F47 tolerance curves based on temporary reduction accidents, which intuitively reflect the impact of accidents on equipment and provide strong basis for fault analysis.

3. Harmonic spectrum analysisThe device is capable of conducting frequency spectrum analysis on harmonics in the power grid and generating harmonic spectrograms. By observing the harmonic spectrum, the factory can clearly see the content and distribution of each harmonic, thereby identifying the main equipment or circuit that generates harmonics. For example, if it is found that the 5th and 7th harmonic content is high, after investigation, it may be determined that it is a harmonic generated by a high-power inverter, and corresponding harmonic control measures may be taken.

（3） Data storage and communication

1. Large capacity data storageAPView500 adopts eMMC imported high-speed storage chip with a capacity of 32GB, which can store event records, fault waveforms and other data for a long time. The maximum storage time for 1-minute data (Max, Min, mean, 95% probability large value, root mean square value) on the device is 90 days, and then it is updated according to the "first in, first out" principle. This allows the factory to access historical data at any time, analyze the long-term trends of power quality changes, and provide data support for formulating power quality improvement strategies.

2. Multiple communication interface adaptationThe device provides rich communication interfaces, including 2 RS485 serial communication interfaces and supports Modbus RTU protocol; 3 Ethernet interfaces, supporting protocols such as Modbus TCP, IEC 61850 MMS, FTP, etc; It also provides an Ethernet maintenance port for accessing web pages and upgrading device software. Through these communication interfaces, APView500 can seamlessly integrate with the factory's automation control system, energy management system, etc., achieving real-time data transmission and sharing, making it convenient for factory management personnel to remotely monitor the power quality status.

（4） Alarm and recording function

1. Custom threshold reportUsers can set limits for steady-state and transient power quality indicators on APView500 based on the actual requirements of factory production equipment for power quality. When a certain indicator exceeds the set threshold, the device will immediately activate the alarm function, informing relevant personnel in a timely manner through sound and light alarms, SMS notifications, email pushes, etc., so as to quickly take response measures and avoid serious impact of power quality problems on production.

2. Wave recording functionThe device can trigger waveform recording for each alarm event, and also provides manual triggering waveform recording, timed triggering waveform recording, and upper computer triggering waveform recording functions. The waveform recording data includes fault waveforms and steady-state data within 2 hours, which are of great value for analyzing the causes and development process of power quality problems and helping factories formulate effective solutions.

Ankerui's APView500 power quality online monitoring device, with its powerful functions, can provide support for factories to timely detect, analyze, and solve power quality problems, effectively ensuring the normal operation of factory production equipment, reducing energy consumption, minimizing economic losses caused by production interruptions, and enhancing the overall production efficiency and competitiveness of factories. It is an important guarantee equipment for modern factories to achieve reliable, efficient, and energy-saving production.
