PROBLEM 5 a Discuss the consequences of short circuit faults on electric power systems [5 Points Protective schemes are routinely used for electric power transformers. Name at least three different types of transformer protective schemes (by function) and explain briefly their principles of operation. [5 Points] Consider the system shown in the single-line diagram of Figure (4 per unit to the same base. Assume that the voltage at both sources is 1 p.u .) All reactances are shown in ind...
Explain the reasons for applying system grounding in electric power systems. [4 points]
Consider the industrial plant distribution bus which is scpplied by a utility source with per-unit sequence reactances as shown in Figure (4-a). Assume that all reactances are given on a \(5,000-\mathrm{kVA}\) base, and that the plant"s bus voltage is \(4,160-\mathrm{V}\).
b- Determine the fault current for a single line to ground fault on phase A of the bus. \([4\) points]
Assume now that an ungrounded \(5,000 \mathrm{kVA}\)...
Q6: Discuss the significance of The Electric Vehicle to the electric power grid. Rationalize the impact of reliability, sustainability, and resilience as applied to the grid. Integrate course material with your research to develop original thoughts. Consider safety, limitations, and economic opportunity? Do you see this as a worthwhile initiative? Think big (globally, if needed)- as we have discussed in class.
discuss two consequences of scarcity
Faults in a control circuit that can make a motor fail to start.
Question 4. An overhead power line for an electric train is suspended at short intervals by thin wires 1m long from the ceiling of a tunnel. If the powerline is duplicated by another one parallel to the first at a separation of 100mm, find the maximum current that can be carried in each cable at the same time before the cables touch. The cables weigh 2kg per metre of length and have a diameter of 20mm.
Question 21 2 pts Which of the following solar power systems can supply both electric power and hot water? Solar power tower Solar thermal panels Solar photovoltaic panels Hybrid PVT system Concentrated solar power
1) In a circuit with current I and voltage V, the electric power delivered to the circuit for direct current is: for alternate current with peak Io and Vo power is: 2) For a straight wire that has a length L and carries a current I, the magnetic force has a magnitude: F -T Where θ is the angle between the direction of l and B. 3) If a current I exists in a coil of wires with N turns,...
