Introduction
When building trans-European high-speed railways the design of the overhead contact line shall comply with EN 50119:2001. The design and operation of overhead contact lines presumes that pantographs are equipped with an automatic dropping device (ADD) (see High Speed
Rolling Stock TSI clauses)[1]. ADD is a device that automatically lowers the pantograph on electric trains to prevent additional damages in case of obstructions or emergencies. It is also known as pantograph dropping device [2].
