Principle and function of Earthing switch
Grounding switch, a kind of isolating switch, is mainly used in the work of circuit grounding part. It does not need to carry the current under normal circuit, but needs to carry the current under abnormal conditions for a certain period of time, such as short circuit circuit circuit. This paper introduces the working principle of grounding switch in detail.

What is the harm of replacing copper with aluminum in transformer?
After investigating a number of power accidents, it is found that the problem of "replacing copper with aluminum" in distribution transformers has not been banned. After production, it is difficult to identify the appearance and terminal blocks of the finished products, and it is difficult to find the test items specified in the existing standards. At the same time, the core hanging disassembly inspection is a destructive method, which is difficult and uneconomical.

What is the difference between inverter overload and overcurrent?
Overload is a time concept, which means that the load exceeds a certain multiple of the rated load in a continuous time. Overcurrent is a quantitative concept, which refers to how many times the load suddenly exceeds the rated load.
