Due to the high number of electronic devices and components in limited space, the Electromagnetic Compatibility (EMC) is an important issue in motor vehicles. In modern electrically powered cars high power has to be transmitted over the vehicle’s electrical power system. This leads to enhanced requirements for the EMC as well as new methods for characterization of Electromagnetic Interferences (EMI) are necessary. In this contribution a measuring system is described which can be used to measure transient voltage and current pulses on high-voltage power networks in normal driving conditions. The devices of the system are tested of its electrical characteristics and some measuring examples conduced at a hybrid car are shown.
