I have come across a discussion on this website on three phase power evacuation through single core cable system. The economic and technical aspects of the system has been nicely touched. We have two types of hydel power plants , one having induction generators and other having synchronous generators.Induction Generators are having 4- core power cable evacuation system and Synchronous Generators are having 4 single core evacuation system. Practically the 4 core power cable system has got damaged early whereas the 4 single core power cables are intact after its use for almost 10 years.I want to replace the 4 core power cable system with 4 single core power cable system. From the respected experienced members I want to know the Advantages and Disadvantages of using Both the system over each other.What are the factors which are usually considered while selecting such systems.
