Avoid hazardous conditions
The Interlocking circuits in railway signaling are often supplied from battery or power supply sources in which neither of the poles are connected to earth
In the event of a single fault, there is no danger, however, two or more faults occurring at the same time could create a dangerous situation
It is vitally important to supervise the battery and power supplies continuously to prevent this from happening.
Cables that run in parallel with AC electrified railways are subjected to induced voltages. If a ground fault occurs in the cable, these voltages can disturb devices that are connected to both cables. When ground faults occur in both supply and return wires, yet another hazardous condition is created.
These faults can be detected reliably with EarthSense.
EarthSense® monitors and detects ground faults in electrical installations where high reliability of power supply is required
