ABSTRACT: A novel method of measuring the positive-sequence capacitance
of T-connection transmission lines is proposed. The mathematical model of the
new method is explained in detail. In order to obtain enough independent
equations, three independent operation modes of T-connection transmission lines
during the line measurement are introduced. The digital simulation results and
field measurement results are shown. The simulation and measurement results
have validated that the new method can meet the needs of measuring the
positive-sequence capacitance of T-connection transmission lines. This method
has been implemented in the newly developed measurement instrument.
