Quickly detect power grid abnormal events and solutions

The quality of power has a serious impact on the military industry, precision instrument processing industry, aerospace, railway transportation, communication and other industries. If abnormal power events in the power grid cannot be found in time and effectively responded to, it will cause serious security accidents. Then how to quickly detect the quality of the power grid in real time? Why use a power quality analyzer?

Various electrical power events in the power grid often indicate some abnormal quality of the power grid. Finding these abnormalities in time and taking countermeasures will be of great help to ensure the quality of the power grid and reduce economic losses and accidents caused by the abnormality. Conversely, if the abnormal electrical energy events in the power grid cannot be found in a timely manner, serious safety accidents will result.

The quality of power has a particularly significant impact on the military industry, precision instrument processing industry, aerospace, railway transportation, communications and other industries. Traditional quality analysis instruments and new online power quality detection devices The traditional power event analysis has the following characteristics: Generally, it is carried out by hand-held or portable instruments; when the power grid data needs to be analyzed, the operation and maintenance personnel first carry the power detector Wire to the grid site, collect data and export for analysis.

Due to the need for on-site operation, on-site collection, and export analysis, its safety (there is a risk of electric shock), convenience (on-site waiting for data collection), timeliness (lagging of analysis results), etc., all have great shortcomings. There is an obvious time lag for finding anomalous electrical energy in the power grid. Often time and money will be spent monitoring the quality of the power grid after abnormal events occur and cause significant economic losses. With the development of power electronics technology, the large-scale use of non-linear loads has led to excessive harmonics and unbalanced three phases. At the same time, many power quality problems such as voltage sags and inrush currents caused by shock loads have caused a lot of power grid influences. Traditional power monitoring methods have been unable to meet the current requirements for safe, real-time, efficient, and rapid monitoring of the power grid.

How to quickly find and notify of abnormal events in the power grid has become a new type of online power monitor. A new type of online power quality monitoring device is urgently needed. It is connected to the background management system through Ethernet. Only one installation and deployment is needed to achieve long-term stability. Grid quality monitoring. Compared with the traditional electrical energy data monitoring method, online can be more secure (no on-site power operation) and more efficient (on-site microcomputer data collection and analysis, high-performance back-end server for deep data mining) to monitor and analyze grid data. Automatic collection of real-time data, real-time detection and notification of abnormal events. Avoid accidents caused by power quality problems and reduce economic losses. E8300 online power detection device.
