Pantograph & catenary interaction: wave reflection at the end spans of a mechanical section and pantographs contact quality.
The contact force between pantograph and catenary is the most important parameter that should be considered and monitored. Contact force fluctuation is the opposite of contact quality. The more standard deviation in contact force you have, the less contact quality you have. The reason for contact force variation is either non-uniform vertical elasticity of catenary…
