Web1 de jul. de 2024 · Outdoor insulator plays a vital role in high voltage transmission and distribution system. The performance and properties of outdoor insulator may severely affect due to various types of pollutants. The failure of insulation in high voltage system results in loss of supply and a huge loss of electrical energy to distribution utilities. WebCreep is defined as slow plastic deformation at stress levels below the normal yield stress. Creep is very slow at room temperature for most materials. The difference between ceramics and metals is the temperature at which creep occurs. Creep occurs when the temperature is above about 0.4-0.5 Tm. Metals will therefore creep at relatively low ... WebThe distance measure of along the surface of the solid insulating material is called creepage distance. The creepage distance is depending upon the weather condition. Minimum creepage distance are 16-25 mm/kV. For high pollution area, these value must be increased. S No. Degree of Pollution.
