On question 63 do we ignore the reactive power since the real power has even symmetry with the power factor? Two Generators Have The Following Characteristics: thus wouldn't the total power be the following Pt= Real( 293 kVA ang (-cos^-1(.82)) + 1,131 kVA ang (cos^-1 (.9)) )

Does anyone know why the copper losses over a 24 hr period are 12 x 5 instead of 24 x5? NCEES #48, A company is planning to purchase a transformer to supply a load operating on a daily load cycle of 12 hours at full-load and 12 hours at no-load while remaining connected to the supply. The...

Hello everyone, does anyone have any links that demonstrate visualization or drawing representations for this problem? I think I understand the solutions, but I don't completely feel like I truly understand all the variations and intricacies of the question. When using the method of...

Hi everyone, does anyone know what the drawing would like for this problem? I am not certain I understand if I completely understand how the surge look. An industrial plant is served by a 12,470-V M480-V grounded-wye transformer. The high voltage side of the transformer is served from a...

Hi everyone, does anyone know what the drawing would like for this problem? I am not certain I understand what the problem means when they mention auxiliary CTs or how these would be connected to the differential relay. A differential relay circuit connected to protect a delta-wye...

Hello, Can anyone please help me understand this problem? I am having a hard time understanding how to solve this. Thanks Consider a 208/120 V, 3-phase, wye-connected, 4-wire transformer. Each 120-V phase feeds a separate and identical dc power supply comprising a simple full-wave bridge...
