An experimental programme to determine the feasibility of using a reverberation chamber to measure the total power radiated by an arcing pantograph

Pantograph arcing is the main EMC interference source in a high speed train. This paper describes a laboratory replica of pantograph arcing which can be operated in a reverberation chamber. The set-up has been verified by numerical modeling to show it is suitable to replace the real pantograph for investigating the radiation properties of pantograph arcing. Some initial measurements have been taken in the chamber. The results show that the reverberation chamber is working well to measure the power radiated from the arc generated by the set-up.
