12. A partially interconnected three-stage network as shown in Figure 5.14 consists of switches of size 10 x 10 and connects 1000 incoming trunks to 1000 outgoing trunks. The outgoing trunks serve ten routes, each having one trunk connected to each tertiary switch. (a) (i) Compare the number of crosspoints in the network with the number required by a three-stage fully interconnected network with the same number of incoming and outgoing trunks. (ii) What advantage would the fully interconnected network have over that shown in Figure 5.14? (b) (i) Assuming that the traffic is evenly distributed over the incoming and outgoing trunks, determine the grade of service when each incoming trunk originates 0.6 E of traffic. (ii) If the total traffic offered to the network is unchanged but the traffic offered to one primary switch increases by 20%, find the grade of service for these calls. (iii) If the total traffic offered to the network is unchanged but the traffic offered to one outgoing route increases by 20%, find the grade of service for calls offered to that route.

Derrive the equation for impedance and phase shift for Series RLC circuit Connect to the AC Supply, Also draw an impedance Triangle and voltage triangle.(Sir I need more details for this question.Thanks.)

please answer it this question

Deviations in quality of service include power irregularities. Which irregularity occurs when voltage levels drop or sag below an acceptable level? Group of answer choices brown out spike black out surge

I need an expert. I previously sent a request, and the expert divided the time periods equally for both areas A and B. I did not understand how and why this was done. Please explain to me with a diagram why we do this. A generation station of 3 MW supply a two regions A & B .The line losses are neglected and the load variation of these regions is as follow: Region A (Time) 11 a.m From midnight to From 5 am to From 8 a.m to From 11 a.m to Load (kw) Region B (Time) 5 a.m No-load 8 a.m 1200 800 6 p.m No-load From From From midnight to 6 a.m to 3 p.m to 7 p.m to 6 a.m 3 p.m 7 p.m Load (kw) 400 900 No-load 9 p.m 1800 From From 6 p.m to midnight 600 From 9 p.m to midnight 200 1-Plot The daily load curve of the total system.

Solve 34 plz fasttt...hand written plz  i'll give you multiple upvote

Transmission line conductance is usually neglected in power system studies.

Q6: A five-bus network has generators at buses 1 and 3 rated 270 and 225 MVA, respectively. The generator sub-transient reactances plus the reactances of the transformers connecting them to the buses are each 0.3 pu on the generator rating as base. The turns ratios of the transformers are such that the voltage base in each generator circuit is equal to the voltage rating of the generator. Line impedances in pu on a 100 MVA system base are shown in Fig. below. All resistances are neglected. Using the bus impedance matrix for the network which includes the generator and transformer reactances, find the sub-transient current in a three phase fault at bus 4 and the current coming to the faulted bus over each line. Prefault current is to be neglected and all voltages are assumed to be 1 pu before the fault occurs. (2) 3 j0.126 1.0/0° j0.168 0/0° j0.1111 lll j0.1333 j0.210 ell j0.126 ll j0.252 4 j0.336 hellte

1. FIGURE 52 shows the one-line diagram of a simple three-bus power system with generation at bus I. The voltage at bus l is V1 = 1.0L0° per unit. The scheduled loads on buses 2 and 3 are marked on the diagram. Line impedances are marked in per unit on a 100 MVA base. For the purpose of hand calculations, line resistances and line charging susceptances are neglected a) Using Gauss-Seidel method and initial estimates of Va 0)-1.0+)0 and V o)- ( 1.0 +j0, determine V2 and V3. Perform two iterations (b) If after several iterations the bus voltages converge to V20.90-j0.10 pu 0.95-70.05 pu determine the line flows and line losses and the slack bus real and reactive power. 2 400 MW 320 Mvar Slack 0.0125 0.05 300 MW 270 Mvar FIGURE 52
