WebGrading of cable is meant the distribution of dielectric material such that the differences between the maximum gradient and the minimum is reduced, thereby a cable of same … WebApr 6, 2024 · Grading of a cable: Grading of a cable is nothing but the process of achieving uniform electrostatic stress in the dielectric of cable. This is achieved by making potential gradient equal throughout the dielectric layer. It can be done in two ways : (i) Capacitance grading. (ii) Inter-sheath grading.
4.6 GRADING OF CABLES - RCET
WebMay 2, 2024 · The process of achieving uniform electrostatic stress in the dielectric of cables is known as grading of cables. The electrostatic stress in a single core cable has a maximum value(gmax) at the … WebJan 23, 2024 · Inter-sheath Grading: In this method, instead of using various dielectrics and having a composite dielectric, we use a homogeneous dielectric material. However, in order to distribute the stress properly, we use extra metallic sheaths between the conductor and the main sheath. These intermediate sheaths are called ‘inter-sheaths’; These ... florists in wagga wagga
