1.what are relationships between voltage level, line loss, transmitted power /distance, and cost of primary electrical equipment?
2.What is grounding system? How many items will be affected by the selection of grounding system?
3.list all the mode of grounding system
4.please draw a phase diagram of a non-ground AC system and tell what are main aspects in normal operation?? If U phase is metallically grounded, what are main aspects of operation?
5.please draw a phase diagram of a AC system grounded by a arc suppression coil? If U phase is metallically grounded, what are the additional currents occurring?
6.What are full-compensation, under-compensation, and over-compensation of arc suppression coil ground AC system, and why first two options are not applicable in system selection??
please solve all
