Series tee splitter for impedance measurements

DWPI Title: Series tee splitter for performing impedance measurements for power system devices, has primary electromagnetic transmission line and secondary electromagnetic transmission line placed in series path with primary line
Abstract: A series tee splitter comprises a primary electromagnetic transmission line and a secondary electromagnetic transmission line that is placed in a series path with the primary electromagnetic transmission line, wherein a load is attached to the end of the secondary electromagnetic transmission line and a network analyzer is connected to opposite ends of the primary electromagnetic transmission line to measure a load impedance. This configuration increases the high impedance measurement limit of the network analyzer normally seen for reflection measurements. The series tee splitter can be electrically small to provide broadband impedance information.
Use: Series tee splitter for performing impedance measurements for power system devices.
Advantage: The splitter can measure large test objects with high impedances in high frequency and kilohertz ranges needed for power system device characterization in a cost-effective manner.
Novelty: The splitter has a primary electromagnetic transmission line and a secondary electromagnetic transmission line that is placed in a series path with the primary electromagnetic transmission line, where a load is attached to the end of the secondary electromagnetic transmission line, and a network analyzer is connected to opposite ends of the primary electromagnetic transmission line to measure a load impedance. The primary electromagnetic transmission line comprises microstrip line structure, and the secondary electromagnetic transmission line comprises a parallel conductor structure built on a T-shaped substrate with the secondary electromagnetic transmission line on the stem of the T-shaped substrate.
