This thesis presents measurement and simulation technique of cable impedance parameters in 600 V system. Coaxial and twinaxial cables are the two types of cables analyzed. The cables are modelled in finite element method (FEM) software using the concept of transverse electric magnetic (TEM) waves. The impedance parameters are measured in a laboratory with a vector network analyzer (VNA) using short circuit and open circuit method. A comparison and analysis of results is made between the simulation and laboratory measurements. The effect on the impedance parameters due to a solid or braided shield in a cable are discussed. Also, a study is conducted to understand the behaviour of cable impedance for placements and at different heights from chassis/copper frame. Different types of shield groundings are adopted in the measurement setup to understand its main purpose. Furthermore, measurements on the cables of a hybrid bus are also performed and compared with the simulation and laboratory measurement results.
