sähköeristämisen

Sähköeristämisen refers to the process of preventing the flow of electric current through materials. This is achieved by using electrical insulators, which are substances with very high electrical resistance. Common insulating materials include rubber, plastic, glass, ceramics, and air. The primary purpose of electrical insulation is safety, as it prevents electric shock to people and animals by containing the current within conductors. It also protects electrical equipment from damage by preventing short circuits and arcing. In electrical power systems, insulation is crucial for maintaining the integrity and efficiency of the transmission and distribution of electricity. It is applied to wires, cables, transformers, and various components to ensure that electricity flows only where it is intended. The effectiveness of an insulator is determined by its dielectric strength, which is the maximum electric field it can withstand before breaking down and allowing current to flow. Proper insulation is a fundamental aspect of electrical engineering and design, contributing significantly to the reliability and safety of all electrical applications.
