1. Basically similar, depending on the parameters.Power quality monitoringdeviceEquipped with various functions such as power quality monitoring, power metering, lightning overvoltage monitoring, communication protocol conversion, etc., this device can be flexibly applied to various environments such as intelligent buildings, substations, power plants, etc. Widely used in fields such as energy conservation and environmental protection, power, and industry.

2. The device uses ARM and DSP dual core distributed architecture, combined with software algorithms, to ensure that all calculations are time accurate and not miss any details that users are concerned about. Single loop device equipped with a 3.5-inch high-definition LCD display, with a resolution of up to 480 × 320, can display real-time data of major power quality detection indicators in a graphical manner; Equipped with commonly used indicators of power quality exceeding the limit indicator light, it is convenient to view the information of exceeding the limit in a targeted manner.

3. Statistical function: The device has online statistical function for main monitoring indicators, which can calculate the average value and CP95 value of detection indicators within a time period. The device has an IRIG-B (DC) timing interface, which can maintain consistency with the clock of the remote management center, ensuring synchronous sampling of the detection device. The device has a transient recording function, which can record the first 20 cycles and the last 20 cycles of transient voltage events at a sampling rate of up to 1024 points per cycle.

4. The device has a report query function, which can be displayed in the form of line charts, pie charts, and histograms; Convenient for users to extract useful information, they can directly connect to a serial printer and print the queried reports. The device is embedded with a WEB server, which allows for real-time viewing of device measurement data and waveforms, configuration of working parameters, and more through a browser. In the absence of centralized backend monitoring software, remote management can still be achieved through Ethernet, simplifying applications and improving practicality.

5. The device is equipped with 4 relay contact outputs and a power down and alarm multiplexing node. It can be used to execute control functions in user settings such as harmonic exceeding triggering and reactive exceeding triggering, and also supports remote control commands from the monitoring center. The device is equipped with 4 state inputs, which can monitor switch position signals, protection action signals, etc., and trigger the recording function when the input is shifted.
