A 230 MVA, 50 Hz, 2 pole synchronous generator has inertia constant H =4.6 MJ/MVA. Determine the kinetic energy. Assume the machine is running steadily at synchronous speed with a shaft input of 251.065X10³ hp. The initial power angle is 6 electrical degrees. The electrical power developed suddenly changes from its normal value to a value of 190 MW. Determine the acceleration or deceleration o the rotor. If the acceleration computed for the generator is constant for a period of 6 cycles, determine the change in power angle and speed at the end of given cycles.

Refer to the National Electrical Code® or the working drawings when necessary. Where applicable, responses should be written in complete sentences. For problems 1 and 2, six luminaires, similar to Style E used in the Commercial Building, are to be installed in a room that is 12 ft x 18 ft (~3.7 m x ~5.5 m) with a 9 ft (2.8 m) floor-to-ceiling height. The spacing ratio for the luminaire is 1:0. 1. The maximum distance that the luminaires can be separated and achieve uniform illuminance is ft ( m). For problems 2-5, two luminaires, 8 ft (2.5 m) and 4 ft (1.2 m) in length with dimensions as shown in Figure 15-7, are to be installed in tandem (end to end). The end of the long luminaire is to be 2 ft (600 mm) from the wall. 2. The center of the outlet box should be roughed in at ft ( m) from the wall. 3.
