Power quality monitoringdeviceEquipped with GPRS wireless transmission function and remote transmission function, real-time data of various monitoring points can be obtained anytime and anywhere. Through remote control technology, any monitoring point can be modified, set, and undergo special testing at any time. You can view the data recorded by ZS3590 anywhere and at any time, and conduct detailed and in-depth analysis on the upper computer.

If there is an abnormal power event, it can provide an alarm prompt at a faster speed, and through the original data, the equipment number and location of the problem can be quickly identified on the computer. Continuously optimize the monitoring terminal program, which can be easily updated through remote download and installation. Built in large capacity Flash storage disk, ensuring the length of recording time and the integrity of recorded data.

The standards for online monitoring of power quality include harmonic voltage, harmonic current, voltage deviation, three-phase voltage imbalance, three-phase current imbalance, three-phase voltage sequence component, three-phase current sequence component, frequency deviation, fundamental active power, fundamental reactive power and power factor, harmonic reactive power, short-term voltage flicker, long-term voltage flicker, inter harmonics, voltage variation, voltage surge, voltage drop, short-term power supply interruption, etc. The format and content of the online power quality monitoring report can be customized by the user, and generated based on the set time or event triggering.

Users or system administrators can view reports through email, fax, or web browsing. The diagnostic report includes power quality exceeding limits, compliance with power quality standards, and power load curves. The level of alarms can be defined and different treatments can be made based on the level. For example, ordinary alarms are only displayed in the monitoring center, and alarms can be sent to designated management personnel through email or SMS or uploaded to a higher level control center.

The historical record of alarm information can be queried and counted, and supports real-time printing. Confidentiality permission for online monitoring of power quality: Used to restrict users' access to data, preventing data from being viewed arbitrarily and preventing data loss.
