EarthLogger 100% is designed and manufactured in​ Australia

Despite all the safety built into electrical systems, failures can and do occur

The EarthLogger is designed to be used in unearthed IT systems where high reliability of the supply is required. Eg. railway, industrial, marine and power applications.

Insulation resistance is the determining factor with respect to personal, equipment and fire safety

The insulation resistance on new installations and electrical equipment is usually very good. Over time, however, operation causes an inevitable reduction in insulation resistance.

This degradation is monitored and safety is maintained through the use of MRD’s EarthLogger.

EarthLogger serves as an early warning system by providing notifications when the impedance between an active phase conductor and earth drops below a set value

The insulation resistance is logged and data can be viewed remotely giving operators the information they need in order to take appropriate maintenance measures.
