The APView series Power Quality Analyzer utilizes a high-performance multi- core platform and an embedded operatingsystem. It includes many functions such as harmonic analysis, waveform sampling, voltage sag/swell/interruption detectionflicker monitoring, voltage unbalance monitoring, event recording, and measurement control. The analyzer complies with suchstandards as IEC 62053-22 Class 0.2S, IEC61000-4-30 Ed3 Class Aand IEC61850 for Substation Automation System. Itis suitablefor power quality monitoring in 11okVand below power supply systems and is widely used in industries such as semiconductor, petrochemical, steel, hospitals, data centers, and transportation buildings, as well as in renewable energy system like photovoltaic, energy storage, and wind power.

Wireless temperature is suitable for �-��kV indoor medi um-voltage switchgears, including handcart switchgears, fixed switchgears and ring main unit . It is also suitable for �.�kV low-voltage switchgears such as fixed switchgears and drawer switchgears. The wireless temperature sensors can be installed on heat-prone joints inside the cabinet, such as circuit breaker contacts, cable joints and copper bar connection joints. The wireless temperature sensor utilizes the wireless data transmission technology to send real-time monitored temperature data to the receiver.In addition, the receiver then transmits the data to a display device or power monitoring system.

The APD series medium-voltage switchgear par tial discharge monitoring device monitors partial discharge signals during the operation of electri cal equipment through ultra high frequency (UH F)sensors, transient earth voltage（TEV）sensors, and acoustic emission（AE）sensors, thereby determining whether there are insulation risks inside medium-voltage electrical equipment and providing early warning.
