Consider a bank of three single-phase two-winding transformer whose high-voltage terminals are connected to a three-phase, 13.8 kV feeder. The low-voltage terminals are connected to a three-phase substation load rated 2.4 MVA and 2.3 kV.
b. To maintain one per unit voltage at rated load, find the per unit generator voltage needed. c. Find load current in amps, current through the transmission line in amps, generator current in amps, and the genertor voltage in volts.
A rigid container holds hydrogen gas at a pressure of 3.0 atm and a temperature of 2.0° C. What will the pressure be if the temperature is raised to 10° C
(a) Design a high-pass filter with a cutoff frequency of 40 kHz. Use 0.01 uF capacitor and an appropriate resistor. B) Sketch and label the circuit. C) What is the gain of the filter at the cutoff frequency Give your answer both as ratio (Vout/Vin..
a. The mass of an electric car is 900 kg including the passengers. A single motor mounted on the front wheels drives the car, and the radius of the wheel is 0.3 m. The car is going downhill at a speed of 50 km/hr, and the slope of the hill is 30 d..
What is the voltage drop on a feeder 450 ft long 4 uncoated copper wire in steel conduit. V=480 3 phase four wire 60 hz. 64 amps .85 pf.
Your battery uses 4 Amperes to transfer 3 joules of charge through an element in a minute. What is the voltage across the battery AND what is the charge in Coulombs
The equivalent circuit for a typical automotive battery charging system is a three-phase delta-connected source which represents thestator coils of the alternator. a) Sketch the load voltagevoltage vt(t) to scale vs time.
Systems that operate under real time conditions need to be causal - that is, they can only process present and past inputs. When no real time processing is needed the system can be non-causal.
A half wave dipole antenna is operating in air at a frequency of 100 MHz. At a distance of 1000 km and at an observation point ? = ?/2, electric field strength is measured to be 5 µV/m. Calculate the a. Length of the antenna
