Q5. A 3-phase, 50 Hz , 100 Km transmission line has conductors composed of 12 strands of Aluminum wound around a core of 7 steel strands. Each of the aluminum and steel strands has a diameter of 0.28 cm. The resistivity and T constant for the aluminum are given by 2.85 ×10° N m at 20 C, and 228 respectively. The steel strands carry no current due to the skin effect. If the line conductors are placed at corners of an equilateral triangle of 2 m a side. Determine : 1- The conductor resistance per Km of the line at 40° C 2- The line inductance and capacitance. 3- The voltage and current at the sending end, if the receiving end voltage is 132 KV .
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.
