A current is measured at the neutral ground of a star load, of equal impedances in all three phases. Which of the following conditions is NOT possible? A) The currents in the three phases are equal in magnitude and angle. B)One phase of the supply conductors was left in open circuit. C) The line-to-neutral voltages in the load are equal in magnitude and with 120° phase shifts between them. D) None of the above
Short Transmission Line
A short transmission line is a transmission line that has a length less than 80 kilometers, an operating voltage level of less than 20 kV, and zero capacitance effect.
Power Flow Analysis
Power flow analysis is a topic in power engineering. It is the flow of electric power in a system. The power flow analysis is preliminary used for the various components of Alternating Current (AC) power, such as the voltage, current, real power, reactive power, and voltage angles under given load conditions and is often known as a load flow study or load flow analysis.
Complex Form
A power system is defined as the connection or network of the various components that convert the non-electrical energy into the electric form and supply the electric form of energy from the source to the load. The power system is an important parameter in power engineering and the electrical engineering profession. The powers in the power system are primarily categorized into two types- active power and reactive power.
