A transformer is used to step down the voltage from a 230 V outlet so that an appliance rated at 115 V may be used. The appliance is a constant power load, that is, it draws constant power as long as the voltage across it is near 115 V. The transformer has an impedance equal to 0.5 + j0.8 Q referred to the high-voltage side. The appliance is consuming 1,800 W at 0.88 power factor lag. It was measured that the voltage across the load is 110 V. What is the rms voltage across the supply? Specify the magnitude only. No need to provide the angle. Provide 2 digits after the decimal point. Answer: What is the real power lost in the transformer? Provide 2 digits after the decimal point. Specify the units. Answer:

I have just started my first Semester (Fall 2021) out of 4 semesters in Master of Applied Science (M.A.S) in Power Engineering at Illinois Institute of Technology. I did not clearly undersand the course enrollment system because I am new to the system, so I ended up enrolling in courses; ECE58-Microgrid Design and Operation, and ECE579-Computer Aided Design of Electrical Machines. It appears ECE582 listed ECE418 (Power System Analysis) as a prerequisite; and ECE539 requires ECE319 (Fundamentals of Power Engineering) and ECE412(Hybrid Electric Vehicle Drives) as prerequisites. Let me hasten to add that I graduated in 2009 in a different academic setup in Africa in Electrical Engineering. So, not only do I have to cover the gap of about 12 year out of classroom, but I have compounded the problem by jumping into advanced courses before enrolling into foundation courses. Unfortunately I can no longer switch courses as the enrollment window has passed. I am only left with one option; to…
An industrial assembly hall is continuously lightedby one hundred 40-W mercury vapor lamps suppliedby a 120-V and 60-Hz source with a power factor of0.65. Due to the low power factor, a 25 percent penaltyis applied at billing. If the average price of 1 kWh is$0.01 and the capacitor’s average price is $50 permillifarad, compute after how many days of operationthe penalty billing covers the price of the power factorcorrection capacitor. (To avoid penalty, the powerfactor must be greater than 0.85.)

Neon signs (which often contain gases other than neon) use high voltage to excite gaseous atoms that then give off a characteristic glow. When plugged into a wall outlet (120 V AC), a typical neon sign transformer delivers 400 W AC at a voltage of 18 kV rms. The primary coil has 400 turns. 1. First, what is the number of turns in the secondary to achieve this high voltage? Give your answer to 2 significant digits. 2. Next, if the transformer is ideal, what is the rms current in the primary? Give you answer in amps with 2 significant digits. 3. Finally, what is the rms current in the secondary? Give your answer in milli-amps with 2 significant digits.
