Problems solved by technology

[0002] In order to ensure the safety and accuracy of power grid power in substations, community power monitoring, smart switchboards, and smart houses, it is necessary to monitor the three-phase current at any time. Once the current is lower or higher than the predetermined value, it may affect electrical equipment. Even if a fire breaks out, it will affect people and property. In the past, people could only get current through on-site measurement, which is very inconvenient, and remote monitoring cannot be done at any time, so it is urgently needed to improve
