Problems solved by technology

[0004] The existing monitoring methods do not monitor the signal comprehensively. When analyzing the signal, they only analyze the abnormal signal, without considering the influence of other environmental factors, and do not analyze the data within one minute before and after the abnormal signal. The results have a greater impact

Abstract

The invention discloses an electricity monitoring method for a three-phase power source. The electricity monitoring method includes the steps of data collecting, real-time analysis and treatment, data uploading and monitoring center analysis. Signals are comprehensively collected and analyzed in combination with all factors, data a minute earlier or later than an abnormal signal are extracted for reference, and a monitoring result is accurate; in the process of monitoring voltage, a capacitive voltage divider is adopted, voltage-withstanding strength is high, response frequency is high, data collection is accurate under normal conditions, and accurate data can also be collected in voltage abnormality caused by thunder and lightning.

Description

technical field [0001] The invention relates to a power monitoring method of a three-phase power supply. Background technique [0002] Power equipment is widely used in various fields in today's society. In order to ensure the safety of power lines, it is very important to monitor power lines or return grid nodes. [0003] Three-phase power supply is widely used in industrial power supply, and the safety of industrial power consumption is very important, so a monitoring method with comprehensive functions and high efficiency is very much needed. [0004] The existing monitoring methods do not monitor the signal comprehensively. When analyzing the signal, they only analyze the abnormal signal, without considering the influence of other environmental factors, and do not analyze the data within one minute before and after the abnormal signal. The results have a greater impact. Contents of the invention [0005] The purpose of the present invention is to overcome the deficie...
