Earth Leakage
Maintained isolation is maintained safety
Without Earth Insulation Monitoring, floating IT systems are just a false sense of security for your personnel and system.
Earth Leakage Detection keeps your site and personnel safe
Unearthed IT systems provide safety and security by allowing a first fault to occur without it immediately causing system failure, potential asset damage and risk of personnel injury/death. However, if this first break in insulation goes unnoticed and isn’t repaired then any subsequent break in insulation will immediately complete the circuit with earth; potentially causing catastrophic damage to any asset or life connected to the circuit at that second.
It is for this reason that Earth Insulation Monitoring is paramount for the safety of your rail system.
Earth Leakage Detector
The ELD is MRD’s flagship product.
Despite all the safety designed into floating IT systems, failures can and do occur. ELD acts as a constant watchdog, alerting you to any leakage from your busbars into earth so that they can be fixed before a second short brings down your system or, even worse, puts a life at risk.
Without Earth Insulation Monitoring, floating IT systems are just a false sense of security for your personnel and system.

EarthSense Monitor
The EarthSense Monitor (ESM) is the newer, smaller, faster and more accurate alternative to the ELD.
Despite all the safety designed into floating IT systems, failures can and do occur. ESM acts as a constant watchdog, alerting you to any leakage from your busbars into earth so that they can be fixed before a second short brings down your system or, even worse, puts a life at risk.

EarthLogger
The EarthLogger is a 4 channel, logging version of the ESM/ELD, allowing you to monitor your whole site with one logger and view the real-time and historical data remotely from an embedded webserver.
Despite all the safety designed into floating IT systems, failures can and do occur. EarthLogger acts as a constant watchdog, alerting you to any leakage from your busbars into earth so that they can be fixed before a second short brings down your system or, even worse, puts a life at risk.

FAQ
TrackSense’ modular design means you can purchase only what you need and expand your site with more I/O extender cards at any time to monitor more/different assets.
Whenever we bring out a new module, your current hardware won’t be made redundant – you can simply slot the new module in and upgrade your site.
Hardware repairs and replacements are made simple and generally won’t even require any site down-time. All you need to do is unplug the damaged module and replace it with new/repaired hardware.
