Safe monitoring of rail vehicles

Locomotives and railcars generally require an electric drive. To ensure high availability, these are therefore often installed unearthed in order to maintain continued operation in the event of an initial fault. Monitoring and troubleshooting systems indicate the fault in order to prevent failures and simplify rectification. Permanent monitoring warns of faults and creeping deterioration in good time, even before critical conditions are reached.  

The insulation monitoring devices are resistant to shock, vibration and temperature, thus meeting the special environmental conditions in the railway environment.  

Earthed power supplies can also be protected with railway-compatible residual current monitoring and voltage relays.
