Abstract :
Based on GPS technology and integral equation, a new method of live line measuring the impedance parameters of T-connection transmission line is proposed. The mathematical model of the new method is explained in detail and the independent measuring cases for live line measurement are introduced. The hardware structure of the measurement system and the digital simulation results are given. The digital simulation results prove that the new method can meet the needs of live line measurement of the impedance parameters of T-connection transmission line.
