Description
The TVM (Traction drive Voltage Monitoring) is generally used as a voltage monitor for the contact wire voltage in DC railway systems. This is necessary, for example, if measurements have to be carried out before the individual sections of a suburban or underground railway are interconnected.
The sections may only be electrically connected if all voltage values are within a certain window.
In addition, the TVM can indicate high voltages in safety areas, e.g. a conductor rail of an underground.
General data
The TVM is a voltage monitor based on analog technology and therefore suitable for highest security requirements. With its specific signal filter, the device ensures that even the impulsive driving voltage of a direct current railway is evaluated correctly.
As soon as the predefined voltage values are reached, the measuring unit begins its activity and shows when threshold values are exceeded or fallen below with ppotential-free changeover switches. It needs no auxiliary voltage as it is directly connected to the catenary or theie supply units.
