Collecting of current is a problem of primary importance in the railroad environment: locomotives currently used on high speed trains supplied with only one pantograph, collect currents up to 2500 A, because of 3 kV system. Under these working conditions, the present pantograph-catenary system reaches extremely critical limits, even though it has been performing normally for many years without particular problems. It's much more difficult to prevent detachment and other problems, when two pantographs are involved at train ends as in the case of the ETR500 train set, where the second pantograph encounters the overhead line that has already been moved by the first. In this connection, research on pantographs is very intense at this time, with a view to developing new technology and new construction philosophies, including equipment with servo-assisted mechanisms. Electrical and mechanical phenomena in pantograph-catenary interaction are very complex and impossible to simulate or reproduce at the test bench. Thus it is of fundamental importance to carry out sophisticated experimental tests in real conditions. The costs of experimentation, caused by the immobilization of train, as well as by the cost of the personnel and equipment involved, can be reduced if the time necessary to carry out tests and to elaborate results are shortened by using dedicated programs developed and executed on a local area network of personal computers.
