Measurement of ABCD parameters of a medium transmission line with magnitude and angle.
Power System Experiment : Measurement of ABCD parameters of a medium transmission line with magnitude and angle. Appratus: variable Voltage Source (Variac) 230V AC with 2-Pole S/W No of π sections: 2 (100Km each) value of each component: Resistance = 4 Ohm; Capacitance = 0.47 microF; Inductance: 110mH. Voltmeter: 230 V AC (2 Nos) Ammeter: 5 A (2 Nos) Watt meter: 300V, 5A (1 Nos) Theory: Medium Transmission Line A transmission line having a length of more than 80 kms but less than 250 kms is considered as a medium transmission line. The parameters (Resistance, Inductance, and Capacitance) are distributed uniformly along the line. For a medium transmission line, charging current is appreciable and due to the length of the line the shunt admittance plays a significant role in the calculation of the effective parameters of the line. The shunt admittance and series impedance are considered as a lumped parameter of the medium transmission line. T...
