reveals the HVDC Light DC transmission technology.It is used in underground transmission and moreover provides point to point transmission.HVDC Light requires only two elements namely a converter station and a pair of ground cables. The new HVDC Light cable is an extruded‚ single-pole cable. It is ideally suited for feeding power into growing metropolitan areas from a suburban substation. HVDC Light is inherent environmentally friendly cables instead of OH transmission lines. Virtually no magnetic

Chapter 16: Energy Management and Audit in Best Exports 16.1 What Is Energy? Energy is the ability to do work and work is the transfer of energy from one form to another. In practical terms‚ energy is what we use to manipulate the world around us‚ whether by exciting our muscles‚ by using electricity‚ or by using mechanical devices such as automobiles. Energy comes in different forms - heat (thermal)‚ light (radiant)‚ mechanical‚ electrical‚ chemical‚ and nuclear energy. 16.2 Definition
