Problems solved by technology

[0002] At present, due to the large number of electrical equipment in the hydropower plant and the complex and diverse environmental conditions, especially the long-term high-temperature and high-humidity environment, there are many hidden dangers of electrical equipment, line insulation damage and leakage, and the risk of personal electric shock and equipment short-circuit damage is extremely high. have serious consequences
Traditional monitoring methods require a large number of monitoring points, and the main monitoring electrical information is voltage, current, power, etc., which makes it difficult to conduct comprehensive analysis and control of the real operation of the load, and it is difficult to meet the monitoring needs of power distribution equipment in power plants
