Physics134 week7 - Coursework ExampleThe functions of the NERC include working with the stakeholders to establish reliability standards for power systems, enforcing and monitors those standards, providing training and educational resources as part of an accreditation program, and assessing adequacy of the resources to ensure operators of the power system atomic number 18 proficient and efficient. NERC analyzes causes of power disturbances to help avoid future disruptions.Long distance power transmission is send on high voltage wires because power is roughly the product of catamenia and voltage. It means that when sending a lot of power, high voltage and high current must be used. High voltage wires atomic number 18 used because high current leads to the loss of power due to the wire resistance. With high voltage wires, the current is small and, therefore, much power reaches the destination.When using high voltage transmission line where one is doubly the voltage of another, each of them has advantages and disadvantages. Very high voltage transmission lines are beneficial in that they privy transmit power underground and above the ground from power companies to households and individual businesses. The high voltage lines whoremaster also run long distances and maintain the electric power. They are more advantageous to utility companies because they have more power. They are also more efficient due to minimal loss of energy. However, they have an accession danger because of high voltage. Low voltage transmission lines are lee dangerous but lend minimal power due to energy loss.The Grid, DOE Office of Electricity Delivery and Energy Reliability. http//www.oe.energy.gov/SmartGridIntroduction.htm http//www1.eere.energy.gov/tribalenergy/ charge/electricity_grid_basics.html
