The pantograph–catenary system plays the crucial role in high-speed electric trains for electrical power collection, where continuity and smoothness of the contact between the pantograph and the ...

By solving the system with the values of piezoelectric outputs, current to be measured can be derived. Results of experiments of passive sensing are presented, proving the validity of the proposed ...
