To prevent excessive voltage rise, and to dissipate this excess energy, trams are usually equipped with a resistive dump, such that if the catenary voltage rises too high, excess energy is dissipated as heat. The downside of this feature is that it lowers overall system energy efficiency, since the regenerated energy is not usefully utilised.
