Safely Critical DC Series Arc Detection and Measurement in Medium and High Voltage Powertrains

Direct Current (DC) series arc faults, caused by e.g. loose connectors, can be a significant safety concern in medium to high voltage powertrains. These faults can cause fires due to the high temperatures generated by the arcing. Hybridization and electrification increase the operating voltage in small drivetrains and the risk of DC series arcs should be taken into account. This poster presents an introduction to the topic and gives an overview of an arc detection test bed. Given the increasing electrification of vehicles and the associated risks of electrical faults, it is possible that specific regulations for DC series arc detection could be introduced in the future.
