a single phase 440V 80kW load with a lagging Pf of .8 is supplied through a feeder of .6+j1.6 ohms and a single phase 100 kVA, 220/440 V transformer. the equiv impedance of the transformer referred to the High Voltage side is 1.15+j4.5 ohm.
draw a schematic showing the transformer connection, determine the voltage at the high voltage terminal of the transformer and the voltage at the sending end of the feeder.
Understanding low, high and band pass filters, A signal in the IF section of an FM radio receiver occupies the frequency band 10.61 MHz to 10.79 MHz. Compute the bandwidth of this signal.
What is the smallest frequency that can be used to sample each of the following continuous-time signals such that the signal can be recovered from the discrete samples (a) \(x(t)=1+cos(2000\pi t)+cos(4000\pi t)\)
For the system described by the following equations, with the input x(t) and output y(t), determine which are invertible systems and which are noninvertible. For the invertible systems, find the input-output relationships of the inverse system.
A continuous time system is described by y(t) = t tan(x(t)). The continuous time system is sampled every T seconds to obtain a discrete time system y[n]. determine the mathematical expression for y[n].
the magnetic circuit of an inductance coil has a reluctance of 1500 A-t/Wb. the coil is wound with 200 turns of aluminum wire, and draws 3 A when connected to a 24-V battery. determine (a) the core flux; (b) the resistance of the coil.
Determine the maximum and minimum spectral frequencies received from a stationary GSM transmitter that has a center frequency of exactly 1950.000000 MHzassuming that the receiver is traveling at speeds of.
what would be the advantage, if any, of using a general equilibrium analysis to answer this question? Illustrate diagrammatically.
A half-wave rectifier circuit with a 1-k ohm load operates from a 120-V (rms) 60-Hz household supply through a 10-to-1 step-down transformer. It uses a silicon diode that can be modeled to have a 0.7-V drop for any current.
An Electrical System is rated 10kVA, 200V at a .5 leading the power factor. a. determine the impedance of the system in rectangular coordinates. b. find the average power delivered to the system
a)Determine I, VR, and Vc in phasor form. b)Calculate the total power factor, and indicate whether it is leading or lagging. c)Calculate the average power delivered to the circuit. d)Draw the impedance diagram e)draw the phasor diagram of the voltage..
A clever student notices that a high constant loop gain would make the PLL converge in frequency and phase. Rather than use an amplifier with infinite gain the student decides to just use an unstable filter.
Three loads are connected in parallel across a single-phase source voltage of 240 V (RMS). Load 1 absorbs 12 kW and 6.667 kVAR; Load 2 absorbs 4 kVA at 0.96PF leading; Load 3 absorbs 15 kW at unity power factor.
