Chapter 3, Problem 3.21P

In a region exhibiting spherical symmetry, electric flux density is found to be D = p 0 r / 3 a , ( 0 < r < a ) , D 2 = 0 ( a < r < b ) and D 1 = ( a 3 p 0 ) ( 3 r 2 ) a , ( r < b ) . ( a )

Find the charge configuration that would produce the given field. (b) What total charge is present?

Q2. a) Two three-phase transformers, designated A and B, have the following secondary equivalent circuit parameters per phase: R₁ = 0.002 Q, XA = 0.03 Q, RB = 0.004 Q, X = 0.012 Q Transformer A is 250 kVA and transformer B is 450 kVA. Calculate how they share a load of 650 KVA when connected in parallel (assume the voltage ratios are equal) b) A step-up transformer is being specified for the beginning of a 3-phase, 4 wire high voltage transmission line. Discuss your recommendation for the configuration of the transformer connections on both the primary and secondary side of the transformer. c) Define power system protection and describe its fundamental purpose. Discuss the following key concepts including discrimination, stability, speed of operation, sensitivity, and reliability in the context of the power system protection components and schemes.
Q3. a) Given the unsymmetrical phasors for a three-phase system, they can be represented in terms of their symmetrical components as follows: [Fa] [1 1 Fb = 1 a² [Fc. 11[Fao] a Fai 1 a a2F a2- where F stands for any three-phase quantity. Conversely, the sequence components can be derived from the unsymmetrical phasors as: [11 1] [Fal Faol Fa1 = 1 a a² F 1 a² a a2. Given the unbalanced three-phase voltages: V₁ = 120/10° V, V₂ = 200/110° V, V = 240/200° V Calculate in polar form the sequence components of the voltage.
