The online monitoring product series includes a laser photoacoustic spectroscopy transformer oil dissolved gas content monitoring system, a lightning arrester online monitoring system, a neutral point flexible grounding system, etc.

1. The laser photoacoustic spectroscopy transformer oil dissolved gas content monitoring system is a new generation of online dissolved gas analysis equipment. The content of characteristic gases dissolved in the transformer insulating oil contains information about the operating status of the transformer. Quantitative analysis of the characteristic gases can predict the fault conditions of the transformer in a timely manner, thereby avoiding more serious accidents.
2. According to the regulations of DL/T 596 Preventive Test Code for Electric Power Equipment and relevant technical standards of the State Grid Corporation of China, the discharge times of lightning arresters in substations and transmission lines should be counted. When using traditional lightning arrester discharge counters, manual recording is required, which has difficulties such as difficulty in data acquisition and management. The passive wireless lightning arrester intelligent sensing system has the characteristics of real-time monitoring of the operating conditions of lightning arresters, no need for external power supply, and safe and accurate data, meeting the relevant needs of lightning arrester maintenance to the greatest extent. The system is divided into a lightning arrester intelligent sensing system for transmission lines and a lightning arrester intelligent sensing system for substations, which can meet the needs of most grid users.
