1. Suppose that transmission line 3 in the previous problem (between Busses 2 and 3) is open circuited for maintenance. Find the bus voltages and transmission line powers in the power system with the line removed. Are any of the voltages out of tolerance? Are any of the transmission lines overloaded?
2. Suppose that a 40 MVAR capacitor bank is added to Bus 3 of the power system in Problem 11-5. What happens to the bus voltages in this power system? What happens to the apparent powers of the transmission lines?
A circuit contains a known resistance of 2.4 kO, and an unknown inductance. a) When a 12-V battery is connected, what is the current in the circuit a long time after the switch is closed
Explain what happens if R was chosen to be linear? Use the given values of resistances, line currents under the bus fault, CT ratios and relay setting. Explain what happens if, during normal operation (that is if there are no primary side faults),..
A symmetric confocal resonator with mirror spacing d = 16cm,mirror reflectances 0.995, and n =1 is used in a laser operating atλo = 1μm. a) Find the radii of curvature of the mirrors. b) Find the waist of the (0,0) Gaussian) mode.
