Transformers are widely used for industrial and residential applications. In long distance electrical power transportation, they play importants role for efficiency and safety improvement by increasing and decreasing the voltage levels during transmission. However, some aspect in using of the transformer need to be considered as they can have bad effect to the enviromental. Please discuss the potential risks of the transformer to the environment and the important actions to be taken to reduce the risk for environmental sustainability.
When the transformer is loaded in a balanced fashion up to its nominal rating (10 MVA), calculate the high side line-to-line phasor voltages (ab, bc, ca). and low side phasor voltages both line-to-line and line-to-neutral (ab, bc, ca, a, b,c). as a reference for calculations the low side A line to neutral voltage is 7620V at an angle of 0 degrees when the transformer is at rated power. The transformer has the following characteristics: V: 138kV delta high side/ 13.2 kV wye low side 9% impedance X/R ratio of 20
Do the following: Solve for the voltage across the appliance and the current through it by referring the appliance to the transformer primary. (Assign the convenience outlet voltage as the reference phasor i.e. at 0o) Draw the circuit that would solve for VL and IL. Compute all referred values and label all components. Solve for VL and IL
