5. Three generators, each rated at 10 MVA and having a reactance of 10 percent, are connected to a common busbar and supply a load through two 15-KVA step-up transformers. Each transformer has a reactance of 7 percent. Determine the maximum fault MVA on the high-voltage side. a. 68.18 MVA b. 136.36 MVA 100.00 MYA

How can unwanted latches be prevented most efficiently? Select one: ° a. None of the above ° b. By replacing IF-statements by CASE-statements. c. By giving default assignments to all signals before the IF- or CASE-statement. ° d. All of the above

Air pressure in a tank is measured and the related digital value is transmitted to the control room using signed two's complement form along with an even parity scheme. Tank's digital air pressure value is considered a binary number that varies between (-3) bar to (+3) bar. The received binary number along with the parity is checked in control room. If there is a negative pressure then a yellow LED should turn on to indicate the low pressure. If the tanks pressure is above (+1) bar a green LED should turn on to indicate an acceptable pressure. If the parity shows that a wrong value is received then a red LED should turn on indicating a transmission error. - Give a truth table that will define the outputs for three LEDs. - Write the simplest expression you can for all LEDs. - Draw a circuit to implement your design.
