Difference between low-voltage and high-voltage electroscope Low voltage electroscope: It is used to test low-voltage electrical equipment with a voltage of 1000V or less to ground, and is also a commonly used safety tool for electricians in families. It has the characteristics of simple structure, wide application range and easy operation, High voltage electroscope: it is used to test the high voltage electrical equipment whose voltage to ground is above 1000V. It has the characteristics of complex structure, high working voltage and high reliability requirements. Difference between low-voltage electroscope and high-voltage electroscope: 1. Type: low-voltage electroscope: pocket electroscope: rotary angle adjustment type, GDY-WBJ0.1-10KV; folding type, GDY-ZD0 -
Usage and work items of electroscope Electroscope is a portable device used to detect the existence of working voltage on electrical equipment, also known as high-voltage electroscope, acousto-optic electroscope, acousto-optic alarm electroscope, electroscope, AC electroscope, telescopic electroscope, etc. Before using the electroscope, two tests should be carried out: the indicator starting voltage test and the insulating rod power frequency withstand voltage test. During power maintenance, the power supply shall be cut off first, and then the electroscope shall be used to test the electricity. Usage and precautions of electroscope: 1. Select appropriate electroscope: use the same voltage class according to the rated voltage of the tested equipment -
Characteristics and application fields of grounding wire Characteristics and application fields of grounding wire Grounding wire is an important electrical equipment, which is widely used in various fields. First, in the industrial field, grounding wires are used to protect the safety of workers and equipment. A large amount of static electricity will be generated in the process of industrial production. If it is not grounded in time, it may cause fire or personal injury risk. The introduction of grounding wire can lead static electricity into the ground, and maintain a safe and stable working environment. Secondly, in the construction field, the grounding wire plays a role in protecting the safety of buildings and people's lives. The risk of electric shock that may accumulate when the metal structure or pipeline of the building is connected through the grounding wire
