By providing constant monitoring and instant notifications of threshold breaches, EarthSense® Insulation Monitor significantly reduces the likelihood of failure or accidents due to electrical ground faults.
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.

RelayDoc is a product of MRD Rail Technologies
MRD Rail Technologies have been a specialist in the design and manufacture of condition monitoring products since 1991. We have supplied rail networks around the globe with cutting-edge solutions which were designed and manufactured in-house. This allows us a lot of freedom to be creative and innovate, while carefully controlling important factors like cost, quality and lead times.
With an invested focus in the field of asset condition monitoring, our products include rail signalling test and measurement equipment, automatic relay testers, passenger information systems, AWS equipment and more.
The MRD Team have passion and expertise for developing innovative hardware and software solutions that change the way the railway industry approaches network reliability and maintenance. Our products make it simpler for remote operators to monitor the condition of crucial track machinery and obtain the information they need to make timely maintenance decisions based on both exact,and predicted, condition.
