In this article, I shall be discussing the existing underground cable fault location methods. Faults in a cable may vary widely, and similar faults may show different symptoms depending upon the cable type, operating voltage, soil condition, and so on. Faults can be considered to be shorts, opens, or nonlinear. A short is defined as […]
There are large number of lithium cells out there. Many of them look similar, but their specifications and ratings are what set them apart. There’s a very long list of lithium-ion battery specifications. Here we will look at the most important lithium ion battery specifications. Lithium Ion Battery Specifications Capacity The capacity of a cell
A lithium-ion cell is composed of four main parts: The cathode varies between different types of cells but is always a lithium compound mixed with other materials. The anode is almost always graphite, and sometimes includes trace amounts of other elements. The electrolyte is generally an organic compound containing lithium salts to transfer lithium ions. The porous
The demand for electrical energy is increasing day by day. So a boom in the consumption of electrical energy has been seen in the last few decades. It is the very reason for the growth in the field of electrical engineering. Due to this growth, carriers in this field are increasing day by day. Almost
