● Basic monitoring indicators:

○ Grid frequency, three-phase fundamental voltage, current effective value, fundamental active power, reactive power, power factor, phase, etc.

○ Voltage deviation, frequency deviation, three-phase voltage imbalance, three-phase current imbalance, negative sequence voltage, current, voltage DC component.

○ Harmonics (2-65times): including total harmonic distortion rate of voltage and current, harmonic content rate, amplitude, and phase.

○ Advanced monitoring indicators: interharmonics, voltage fluctuation, flicker, voltage surge, sag, short-term interruption, temporary overvoltage.

● Display function:

○ The device panel is equipped with a large-screen color LCD display screen to display the data of power quality monitoring indicators in real time.

○ Setting function: Set, modify and view basic parameters and over-limit parameters of the device, and password protection.

● Record storage function:

○ The device has a built-in TF card, which can save basic monitoring indicators and advanced monitoring indicators in real time. The real-time data can be saved on the device for up to 1 year, and then updated according to the "first in, first out" principle.

● Statistical function:

○ The device has an online statistical function for the main monitoring indicators, and can calculate the three-second average of the monitoring indicators within a minute.

● Communication function:

○ The device provides a variety of communication interface methods to realize real-time transmission of monitoring data or timed extraction and storage records. It can communicate with the remote power quality management center through the industrial Ethernet interface, and can also communicate with the remote through the RS232C/RS485 interface in GPRS mode (customized).

● Time synchronization function:

○ The monitoring device has a network time synchronization function, which can keep the clock consistent with the remote management center. At the same time, it has a B code time synchronization function to ensure the accuracy of the device clock.

● Event trigger recording function:

○ The event trigger threshold can be set according to customer requirements, and the real-time data and waveform before and after the event trigger can be recorded, and the event log can be saved for query.
