3) The single-line diagram of a three-phase system is given in Figure 3. The three-phase generator is rated 4160 kVA, 2.4 kV, and 1000 A. The three-phase transformer T1 is rated 6000 kVA, 2.4Y/24Y kV, with leakage reactance of 0.04 pu. Transformer T2 is made up of three single-phase transformers and is rated 4000 kVA, 24Y/12Y kV, with leakage reactance of 0.04 pu. The load draws 2000KVA with 0.8 PF leading at 12kV. Assume that the line length between the two transformers is negligible. Select a base power value and base voltages DIFFERENT than the ratings of the equipment. Determine the following for all three circuits, 2.4-, 24-, and 12-kV circuits: (a) Base impedance values (b) Base current values (c) Per-unit and actual current values (neglect magnetizing currents in transformers and charging currents in lines) (d) Per-unit and actual voltage values at buses 1, 2, and 4 (e) Per-unit and actual apparent power values at buses 1, 2, and 4 24 kV N1 N2 2.4 kV 24 kV 12 kV N2 N1 Load T1 T2 Figure 3

Analog to Digital Converters

The analog-to-digital converter (ADC) allows circuits controlled by microprocessors, Arduinos, Raspberry Pi, and various reasonable digital circuits to be connected to the real world. In the real world, analog signals have a continuous stream of information from a variety of sources and sensors capable of measuring sound, light, temperature, or movement, in addition to the many digital systems that interact with their environment by measuring analog signals from those transducers.
