1、 Background: The pain points of power quality urgently need to be accurately resolved

With the increasing proportion of industrial electronics and new energy grid integration, power quality problems such as harmonics, voltage transients, imbalances, and flicker in the power grid are becoming increasingly prominent. These issues not only cause damage to precision equipment and interruption of production processes, but also increase power grid losses, affect power supply stability, and even pose safety hazards. Traditional monitoring equipment has shortcomings such as low sampling accuracy, single function, scattered data, and inability to locate disturbance sources, making it difficult to meet the needs of 110kV and below power supply systems for comprehensive monitoring, accurate analysis, and fast traceability of power quality. There is an urgent need for a specialized monitoring device that combines high performance, full functionality, and strong compatibility.

2、 Product Overview: High standard power quality monitoring solution

The APView500 power quality online monitoring device is a monitoring device developed by Ankerui based on a multi-core heterogeneous hardware platform. It strictly follows the IEC 61000-4-30 standard and the national standard A-level requirements, and is suitable for power supply systems with voltage levels of 110kV and below. The product is centered around "full parameter monitoring+intelligent analysis+flexible interconnection" and supports dual circuit simultaneous monitoring. It can comprehensively capture key indicators such as voltage/current effective value, harmonics, interharmonics, transient/transient, and imbalance. With functions such as event recording, disturbance source localization, and PQDIF data export, it provides full process data support for power quality control, fault tracing, and energy consumption optimization. It is an ideal monitoring choice for scenarios such as power grid operation and maintenance, industrial production, and commercial buildings.
