I am seeking ideas or references regarding the auxiliary power output for a trolley. I’ve encountered difficulties finding information online about the power output for lights, buzzers, and speakers. Specifically, I am interested in the following questions:
How many lights, buzzers, and speakers can a trolley approximately 48 feet in length accommodate?How can I determine their rated power?Any guidance or resources you can provide would be greatly appreciated.
Thank you!

Three single-phase transformers rated at 250 kVA, 7200 V/600 V, 60 Hz, are
connected in wye-delta on a 12470 V, 3-phase line. If the load is 450 kVA, calculate the following
currents:
(1) In the incoming and outgoing transmission lines
(2) In the primary and secondary windings
(3) If this transformer is used to raise the voltage of a 3-phase, 600 V line to 7.2 kV. (a) How
must they be connected? (b) Calculate the line currents for a 600 kVA load. (c) Calculate the
corresponding primary and secondary currents.

- Prelab Information 1. Laboratory Preliminary Discussion Second-order RC Circuit Analysis The second-order RC circuit shown in figure 1 below represents all voltages and impedances as functions of the complex variable, s. Note, of course, that the impedances associated with Rs, R₁, and R2 are constant independent of frequency, so the 's' notation is omitted. Again, one of the advantages of s-domain analysis is that we can apply all of the circuit analysis techniques learned for AC and DC circuits. To generate the s-domain expression for the output voltage, Vout(s) = Vc2(s), for the circuit shown in figure 1, we can apply voltage division in the s-domain as shown in equation 1 below. Equation 1 will be used in the prelab computations to find an expression for the output voltage, vc2(t), in the time domain. Note also that when we collect frequency response data for the circuit it will be operating at AC steady-state conditions for each frequency tested.
