| Abstract: | A live line measurement based on the integral equations is proposed for the zero-sequence parameters of T-connection transmission lines.Its mathematical model and the discrete expressions of its integral equations are given.The least squares method is used to calculate its zero-sequence impedance.In order to obtain enough independent equations,6 live line measurement modes are shown.Measurement source acquisition and GPS(Global Positioning System) are the key techniques of synchronous data sampling at diffe... |
