Repeat Example 4.5, assuming ACSR conductors.
Example 4.5
Assume that the feeder shown in Figure 4.33 has the same characteristics as the one in Example 4.3, but the 500 kVA load has an increasing load density. Calculate the percent voltage drop in the main.
A 3-phase, 50 Hz, 400 V motor develops 100 H.P. (74·6 kW), the power factor being 0·75 lagging and efficiency 93%.- Determine the capacitance of each capacitor.
Evaluate the component selection for the differentiator and integrator amplifiers and their impact on the mahematical equation for each. Items for you to consider and discuss are Do you observe any limitation factors for the component parameters an..
In a 2-pole, three phase PMAC synchronous motor, the torque constant kT and the voltage constant kE are 0.6 in respective MKS units. The synchronous inductance, LS is 10 mH. The stator winding resistance per phase is 1 Ω.
Two machines and a lighting load are connected in parallel to a 220 V, 60 Hz line. The first machine uses 40 kW of power at 0.81 power factor lagging. The second machine uses 27 kVA at 0.93 power factor leading. The lighting load consumes 13 kW.
For both designs, the supply voltage is nominally 9 V and varies by +/- 1V. For the first design, assume that the availability of supply current is not a problem, and thus operate the diode at 20mA. For the second design, assume that the current f..
Treat as an ideal gas ie it obeys pV=nRT law where pis pressure, V is volume, n is number of moles, R=82.056*10-6 m3-atm/mole-K is the universal gass constant and T is th absoulte temperature.
The charge leaving the positive reference terminal of a voltage source is q(t)= [6sin120pi*t - 8cos120pi*t]mC the voltage source value is v(t)= 160cos120pi*t V. A) Determine the power supplied by the voltage source at t=0
An engineer intends to study an input signal with frequency components of 5, 6, and 10 kHz. It is desired that all other frequencies be filtered out. A) What kind of filter does this require
Design a Java application that maintains the data for a simple social network. Each person in the network should have a profile that contains the persons name, current status, and a list of friends.
Determine the capacitance.- Find the electric field intensity between the plates. - Find the charge on each plate if the dielectric is air.
It is required to design a full-wave rectifier using a center tapped rectifier to provide an output voltage of 10 v. Find the required number of turns ration of the transformer. Assume that a conducting diode has a voltage drop of 0.7v. The ac lin..
Derive the expression for maximum torque (show all steps) and show that the slip at which maximum torque occurs is directly proportional to rotor resistance, but the maximum torque is independent of rotor resistance.
