(1) Which of the following phasor diagrams is correct for a transmission line with an impedance of 1+j3 2? I is the current of the line, Vg is the voltage at the receiving (load) side of the transmission line and Vs is the voltage at the sending (supply) side of the transmission line (c) (b) (a) Figure 1. Four phasor diagrams but only one is correct for the transmission line of Qla. (0)
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.
