eSmart Systems recently launched a new Earth fault module in Connected Grid that is expected to significantly reduce inspection cost related to earth fault troubleshooting. The module enables earth fault monitoring at transformer and customer level which will bring great insight for determining where the earth fault has its origin.

Earth fault is a phenomenon which means that an undesired current leakage goes from a conductor to earth or to other parts of an installation that should not be energized. As it is difficult to pinpoint where the cause of the earth fault lies, without onsite investigation, the fault location identification often lands on the grid company.

eSmart´s Earth Fault module provides detailed information of the earth fault such as time of occurrence, duration, type of fault and size of the leakage current for further follow up.

Focus on Earth Fault 

Lie explains, the reason for focusing on earth faults is that the IT grid structure, can cause the earth faults to become a danger to life and property. Grid companies for example in Norway are responsible for earth faults occurring in the grid. If the error proves to be within the customer installation, the customer is liable to rectify the error.  
 
An eSmart customer said that one earth fault troubleshooting normally requires 2 resources during one full day, which results in high inspection cost. By using the module in Connected Grid, they have estimated their savings to be up to 2 MNOK.
