​3. Detailed Typical Functions​
The system possesses comprehensive and professional analysis functions, targeting core power quality indicators.

• ​Automatic Flicker Severity Evaluation and Analysis​
• Strictly following the IEC 61000-4-15 standard, it calculates and outputs Short-Term Flicker Severity (Pst) and Long-Term Flicker Severity (Plt) values in real-time. This function objectively evaluates the impact of lighting flicker on the human eye, is particularly suitable for environments with strict lighting requirements, and can effectively assess the impact of fluctuating loads (like welding machines, rolling mill drives) on the power grid.
• ​Accurate Voltage Unbalance Calculation​
• Utilizing the classic symmetrical components method from power systems, it precisely decomposes the negative-sequence and zero-sequence components from three-phase voltages to calculate highly accurate voltage unbalance. This function is crucial for protecting rotating equipment like three-phase motors and generators, providing effective early warnings against motor overheating and reduced lifespan caused by unbalance.
• ​Customized Compliance Report Generation​
• The system features a powerful built-in reporting engine capable of generating power quality assessment reports compliant with a series of Chinese national standards (e.g., GB/T 12325 for supply voltage deviation, GB/T 12326 for voltage fluctuation and flicker, GB/T 14549 for harmonics in public supply networks) with a single click. It also supports custom report templates to meet compliance certification needs for various scenarios such as internal audits, grid connection acceptance by utility companies, and third-party testing.

​4. Core Application Scenarios​
This system is particularly suitable for high-end industrial and infrastructure sectors that are highly sensitive to power quality.

• ​Semiconductor Manufacturing​
• ​Pain Point:​​ Chip manufacturing equipment is extremely sensitive to voltage sags/swells and harmonic distortion. Power quality issues lasting mere milliseconds can scrap entire batches of wafers, causing significant economic losses.
• ​Solution Value:​​ Through 7x24 continuous monitoring and PQF analysis, it quickly locates the source of disturbances causing production interruptions (whether from external grid faults or internal variable frequency drives). It provides precise data support for installing customized power compensation devices (e.g., DVRs), ensuring production continuity and yield rates.
• ​Aircraft Ground Power (400Hz Ground Power Units)​​
• ​Pain Point:​​ Aircraft maintenance and power supply rely on ground-based static frequency converters. The quality of the 400Hz intermediate frequency power they output, including voltage/frequency stability and waveform distortion, is directly related to the safety of avionics and the normal preparation of the aircraft.
• ​Solution Value:​​ It continuously monitors the output quality of the ground power source, ensuring full compliance with aviation industry standards. Through voltage unbalance and harmonic analysis, it assesses the health status of the power supply equipment, enabling predictive maintenance and avoiding flight delays caused by ground power issues.
