Beyond mere fault detection, DC-safe® also calculates the actual value of the insulation resistance, which enables to monitor it and take preventive action before an actual problem occurs.
In case a problem does occur, DC-safe® pinpoints the location where the insulation failure occurred, enabling an efficient service intervention. This is especially important since insulation failures are often intermittent and notoriously hard to locate.
The DC-safe® technology has proven its value on more than 250 hybrid buses all over Europe.
DC-safe® is patented (EP1265076).
It can be implemented in a very compact way in a micro-controller using very few external components.
