Detection of appliance couplers with protection levels higher than IPXO

Both electronics, electrical appliances, and electricity belong to electrical engineering. Electrical is an abstract concept that does not specifically refer to a particular device or device, but rather to the entire system and the scope of electronics, appliances, and power. Electricity is the strong current part of electrical engineering, mainly studying the supply of electricity (i.e. the generation of electricity - power generation systems), transmission (power line transmission), and transformation (high and low voltage transformation, transformers, circuit breakers and contactors); Electricity is divided into high-voltage electricity and voltage transformation and distribution. Electronics refers to the weak current part of electrical engineering, mainly studying the processing and transformation of information; Electronics can be divided into two parts - electronic circuits and electronic systems. Electronic circuits (electronic components: electronic components used to make circuit boards and electronic designs, such as diodes, transistors, silicon, and LED lights. Electronic devices: an electronic functional device composed of a single and multiple circuit boards); Electronic system: A system composed of electronic devices, that is, a weak current engineering system. Electrical appliances are specific equipment, and in a narrow sense, electrical appliances refer to switches in the industrial field. In the civilian field, electrical appliances refer to electrical equipment that consumes electricity (such as washing machines, televisions, refrigerators). Academic definition: Electrical equipment that automatically or manually connects or disconnects a circuit, continuously or continuously changes circuit parameters, and achieves circuit switching, control, protection, detection, and adjustment based on specific external signals and requirements is called an electrical appliance. Electrical is a collective term for disciplines or engineering fields such as the production, transmission, distribution, and use of electrical energy, as well as the manufacturing of electrical equipment. It is a science that uses electricity, electrical equipment, and electrical technology as means to create, maintain, and improve confined spaces and environments, covering three aspects of electricity conversion, utilization, and research, including basic theory, applied technology, and facilities and equipment. A motor refers to an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Represented by the letter M in the circuit (old standard used D). Its main function is to generate driving torque as a power source for electrical appliances or various machinery. The generator is represented by the letter G in the circuit. Its main function is to convert electrical energy into mechanical energy. The relationship between the two is that electrical engineering includes electrical appliances, and motors are the power source of electrical appliances
